— Technical Comparison and Practical Engineering Guidance —

As industrial automation continues to evolve, the reliability requirements for cables used in moving parts have become increasingly demanding. In robot arms, transfer systems, and cable carrier applications, power cables are subjected to continuous bending, sliding, and torsional stress. In such environments, general-purpose fixed-installation cables are not sufficient. Dedicated robot power cables are essential to ensure long-term operational stability.

This column provides a comprehensive technical overview of selection criteria, including electrical capacity, mechanical durability, and a comparative review of three major Japanese products: OKI Electric Cable ORP-D, Hanshin Cable MRC UL2501, and Dyden Robotop DP6.

Operating Environments and Application Scope

Robot power cables for moving applications are typically installed in:

• Industrial robot arms (internal routing)

• Transfer and inspection systems with reciprocating motion

• Cable carriers (energy chains)

• Power supply lines for three-phase motors and servo drives

These applications involve repeated bending cycles that may reach tens of millions or even exceed one hundred million cycles. Mechanical stress is often the primary failure factor, making conductor structure, insulation material, and sheath durability critical design elements.

---

Why Dedicated Robot Power Cables Are Required

Mechanical Durability Under Repeated Motion

Robot cables use finely stranded conductors and optimized internal structures to resist bending fatigue. Compared to standard power cables, they are engineered to withstand long-term dynamic operation.

UL Compliance for Global Equipment

All three products discussed in this article are rated at 600V and 105°C in accordance with UL758 standards. For equipment exported to North America or used in globally standardized production lines, UL compliance is often mandatory.

Shielded and Unshielded Variants

In inverter-driven systems or installations where power and signal cables are routed together, electromagnetic noise becomes a design consideration. Shielded models reduce noise interference, while unshielded versions provide improved flexibility and reduced cable weight.

Although all three products share the same 600V and 105°C rating, their design focus and lineup breadth differ significantly.

---

Allowable Current and Conductor Selection

Allowable current depends primarily on conductor size (AWG) and installation conditions.

As general engineering references:

• AWG12 class: approximately 20A

• AWG10 class: approximately 30A

• Larger conductors (e.g., AWG4): suitable for higher current motor applications

When selecting conductor size, engineers must consider:

• Continuous load current

• Inrush or peak current

• Ambient temperature

• Cable bundling conditions

• Installation method and heat dissipation

Proper derating calculations are necessary, especially in enclosed cable carriers or high-temperature environments.

---

Recommended Minimum Bending Radius

For dynamic applications, a commonly accepted engineering guideline is:

• 6 to 8 times the overall cable diameter

Designing below this limit accelerates conductor fatigue and insulation degradation. In robot arm design, sufficient routing space must be secured at the mechanical design stage to prevent premature failure.

Engineering Selection Checklist

When selecting a robot power cable for moving applications, engineers should verify:

1. Continuous and peak current requirements

2. Required bending cycle life and motion speed

3. Stroke length and routing constraints

4. Noise environment and shielding necessity

5. Compliance requirements (UL, CSA, etc.)

A robot power cable in a moving system functions not only as an electrical component but also as a mechanical element under continuous stress. Electrical capacity alone is not sufficient for proper selection; mechanical endurance must be evaluated with equal importance.

Conclusion

In automated systems, long-term reliability is often determined by components that are not visible—such as internal power cabling. Selecting an appropriate robot power cable directly impacts equipment durability, maintenance frequency, and operational safety.

A careful balance of electrical performance, mechanical flexibility, environmental resistance, and installation constraints ensures stable operation throughout the lifecycle of the equipment.

Curl cords have been around for a long time, but their essential value remains unchanged. Their spiral structure combines flexibility and durability, and their ability to automatically absorb excess length is a feature essential for any device with moving parts. While primarily associated with telephones, they are actually used in a wide range of fields, including industrial equipment, factory automation (FA) systems, medical equipment, retail facilities, and movable furniture. Even in an age of widespread AI and robotics, this structural value may be reevaluated.

Our product lineup includes Nagaoka Electric Wire's general-purpose curl cords, as well as highly flexible custom curl cords based on Oki Electric Cable's robot cables. This positioning us as a leader in addressing changing market conditions. While general-purpose products enjoy stable demand for retail facilities, office automation equipment, and light-load applications, it is high-durability and application-specific custom products that offer greater potential for future growth. This is because, as devices become more sophisticated, the operating conditions of moving parts become increasingly stringent, limiting the number of situations in which standard products are no longer suitable.

The widespread adoption of collaborative robots and compact automated equipment is a prime example. Labor shortages are driving investments in automation, even in small and medium-sized manufacturing companies. However, not all moving parts have strokes or loads large enough to warrant the use of cable carriers. For short reciprocating motions or limited ranges of motion, lightweight and flexible coiled cords offer design flexibility and cost advantages. Furthermore, as equipment becomes more compact, wiring space becomes more limited. A structure that naturally absorbs excess cable length is highly compatible with space-saving designs, contributing to internal organization and improved safety. Thus, the dual trends of equipment miniaturization and increasing functionality are supporting the adoption of coiled cords.

The medical and nursing care fields are also areas where stable demand is expected. Due to the aging population, the number of devices with moving mechanisms, such as height-adjustable medical chairs, rehabilitation support equipment, and home medical equipment, is on the rise. In these fields, safety and reliability are prioritized over wireless technology. For equipment requiring high power output or long periods of continuous operation, the reliability of wired power supply remains important. Furthermore, eliminating excess cords on the floor helps prevent falls and is a rational safety measure in medical facilities. A structure that can absorb excess cords using an extension mechanism offers clear advantages in terms of maintaining aesthetics while ensuring safety.

EV and battery-related equipment is also an area of ​​interest. With the advancement of electrification, demand for maintenance equipment, inspection equipment, and evaluation equipment is expanding. These equipment often handle relatively high currents, making fully wireless deployment impractical from both a technical and safety standpoint. For equipment that repeatedly connects and moves over short distances, custom coiled cords with their elasticity and flexibility are potentially applicable. Robot cable-based specifications, in particular, offer increased design flexibility while ensuring durability against repeated bending and twisting.

Height-adjustable desks and adjustable furniture are becoming increasingly common in offices and homes. While electric lifting mechanisms have become commonplace since the spread of telework, wiring management remains a challenge. The degradation of aesthetics and the risk of wire breakage due to sagging wires directly impact product value. Curl cords, with their elasticity that naturally accommodates excess length, are a rational choice in terms of both design and functionality. While this market is not experiencing explosive growth, it is likely to remain stable at a certain scale.

Looking to the long term, the market is expected to move toward qualitative differentiation rather than quantitative expansion. While improvements in wireless technology and battery performance may replace some applications, wired power supplies remain essential for high-current applications, safety-standard compliant equipment, and long-term continuous operation in industrial applications. Furthermore, as AI advances, the number of sensors and small actuators will increase, resulting in an increase in the amount of wiring in moving parts. In other words, we expect a polarization to continue, with wireless advances advancing while high-reliability wired applications remain.

Amid this structural change, custom specifications optimized for each application will become increasingly important. Demand is likely to continue to grow, including hybrid specifications that combine power and signaling, high-reliability shielded types, and special-environment compatibility such as oil and chemical resistance and low dust generation. As equipment becomes more sophisticated, the need for specifications that cannot be met with standard products will expand. The idea of ​​curling robot cables is a proposal that simultaneously satisfies the requirements for mobility and flexibility, and is an effective differentiating factor.

While curled cords are not eye-catching products, they are essential components that will be necessary as long as machines move in physical space. The possibility of a completely wireless society is limited, and wired devices will continue to play a role from the perspective of high output, safety, and reliability. Going forward, the market is likely to shift away from the mass supply of general-purpose products and instead become more focused on application-specific, high-value-added products. Having a system that can handle both general-purpose products and highly durable custom products will be a major advantage in adapting to this change. Being a niche market does not mean shrinking; rather, it is important to consider it as a market where expertise can be utilized when considering future developments.

Nisho Electronics is a trading company that sells cables and electronic components, and was established in Tokyo, Japan in 1967.In 1976, we became an authorised dealer of Oki Electric Industry, and in 1993, we became an authorised dealer of Oki Electric Cable.In 1996, we became an authorised dealer of OKI Sensor Device (now Standex Electronics Japan).In 2010, we became a distributor of ROHM.In 2010, we opened our own online store, and in 2013, we opened an online store for overseas customers.

When we first started, we sold semiconductors, switches and wires from Japanese manufacturers domestically, but in recent years we have also sold wiring harnesses and parts from Taiwanese manufacturers in Japan. We also focus on exporting and selling products from Japanese manufacturers overseas.

As a supplier in Japan, we also focus on promoting the products of overseas manufacturers in Japan, and we support the promotional activities of overseas manufacturers by posting their products on our own website and on Japanese manufacturing industry websites free of charge.

In the world of electronic components, new technologies emerge one after another, centered on miniaturization and high performance. Meanwhile, there are wiring components that have built up a proven track record and continue to be used in the field. While jumper cables fall into this category of "old technology," there are good reasons why they continue to be selected.

In recent years, major Japanese manufacturers, including Sumitomo Electric Industries, have ceased production of jumper leads one after another. While this movement suggests a shrinking market, in reality, demand for jumper cables has not disappeared due to the continued use of design assets and the existence of industrial equipment still in operation. Rather, stable demand remains, primarily for replacing existing products and maintaining legacy equipment whose specifications are difficult to change.

Amid this market environment, Taiwanese specialized manufacturer YEH CHI (Yeh Chi Electronics) is making its presence known. YEH CHI's main product is jumper cables, supporting a wide range of pitches from 1.27mm to 3.96mm, and specializes in custom manufacturing to customer-specified dimensions. Not only have they become an alternative supplier after domestic manufacturers withdrew from the market, but they are also increasingly being adopted as mounted components for new design projects.

One of the reasons YEH CHI's jumper cables are so highly rated is their on-site design. The terminals are solder-coated, allowing for stable soldering while suppressing oxidation. Their compatibility with through-hole PCBs and the ease of forming solder fillets ensures both connection strength and electrical reliability. Furthermore, the ability to visually inspect the soldered condition is a major advantage in terms of quality control.

Direct wiring to PCBs using jumper cables has a simpler structure than connector connections and is also more reliable over long-term use. By avoiding the risks of disconnection due to vibration or poor contact due to micro-friction wear on the contact surfaces, they are ideal for applications requiring stable operation, such as industrial and infrastructure-related equipment.

Jumper cables are also a cost-effective option. Compared to connectors and harnesses, they not only reduce the number of components but also occupy less board space. YEH CHI offers a variety of pitches, including 3.96mm, 2.54mm, 2.5mm, 2.0mm, 1.5mm, and 1.27mm, and allows you to customize the insulation and strip lengths, optimizing costs without sacrificing design flexibility.

YEH CHI jumper cables are also effective in new development projects. Flexibility to accommodate design changes and quick delivery are particularly important during the early prototyping and evaluation stages of development. Custom jumper cables, with a minimum order of approximately 1,000 units and a delivery time of approximately one month, are ideal for prototype development, compared to FPCs, which require expensive molds and long lead times.

YEH CHI products are UL-certified and can withstand temperatures ranging from -20°C to 105°C and voltages up to 300V. As a result, jumper cables have been adopted in a wide range of applications, from home appliances to industrial equipment. They are a reliable option not only for replacing discontinued products from domestic manufacturers, but also for new designs.

As electronic devices become increasingly denser and more compact, the overall jumper cable market may gradually shrink. However, jumper cables will continue to play a vital role in the maintenance and repair of legacy systems, projects requiring custom specifications, and areas where stable signal quality is important.

YEH CHI (Yeh Chi Electronics) continues to meet this undeniable demand with its long-cultivated manufacturing know-how and flexible response capabilities. For companies that prioritize quality, responsiveness, and supply stability in a seemingly simple product like jumper cables, YEH CHI will remain a valuable partner.

---

Technical Explanation — Why This Structure is Suited for Moving Parts

1. Flexibility from the 49/0.05 Multi-Stranded Conductor

Using many extremely fine strands distributes bending stress along the wire length and greatly improves fatigue life during repeated flexing. Even at the same AWG28 cross-section, “more strands = higher flexibility” is a well-established principle in dynamic cable design (okidensen.co.jp).

2. Benefits of Polyester Elastomer Insulation

Polyester elastomers exhibit strong elastic recovery, preventing deformation and abrasion during repeated bending. When combined with the robust design used in ORP-30F series cables, the insulation provides excellent heat and oil resistance—an advantage in industrial environments (okidensen.co.jp).

3. Design Freedom from Ultra-Thin Ø0.60 mm Insulation

Such a small diameter eases cable routing in narrow spaces, compact joints, miniature mechanisms, and dense connector housings. Designers can benefit from easier wiring paths and reduced mass for moving modules, enhancing motion response (okidensen.co.jp).

UL11527 AWG28 Thin Diameter φ0.60mm White 300m Bobbin

UL11527 AWG28 Thin Diameter φ0.60mm Black 300m Bobbin

--A Comprehensive Analysis of Commercial and Passenger Vehicles, Industrial Structure, and Social Impact-

The Japanese government has set a goal of deploying 10,000 Level 4 autonomous commercial vehicles by fiscal year 2030. This is an important initiative to address social issues such as the growing driver shortage, maintaining logistics infrastructure, and ensuring local transportation. While fewer than 1,000 vehicles are expected to be deployed by fiscal year 2027, a plan has been put in place to rapidly promote deployment from that point toward fiscal year 2030. Support measures for local governments and development companies are also expected to be strengthened, accelerating policies toward the societal implementation of autonomous driving.

Overseas, the United States and China have progressed from the demonstration phase to the commercial phase, and in China, autonomous taxis are already operating in several cities. Japan has taken a cautious approach, but advances in policy and technological development are expected to significantly expand commercial services over the next five to ten years. Demand for autonomous trucks is particularly likely to increase in the logistics sector, and autonomous buses are expected to play an important role as a regional transportation provider in depopulated areas.

In the passenger car sector, the Honda Legend is currently the only commercially available vehicle with Level 3 technology. Going forward, it is expected that Japanese manufacturers will gradually add Level 3 technology to their lineup. In five years, Level 3 will be available on multiple vehicle models, and in ten years, it is likely to become widespread, primarily in flagship and luxury models from major manufacturers. However, Level 4 will require significant regulatory and social acceptance, as well as infrastructure development, and widespread adoption in passenger vehicles will require a longer timeframe.

The key factors in determining whether Level 3 or higher autonomous driving will become commonplace in private vehicles will be its compatibility with the living environment and cost. Five years from now, it is expected to be limited to a limited number of high-priced models, expanding to mid-range models in ten years. In 30 years, highly automated driving may become a common option, with autonomous vehicles likely to become a primary means of transportation in urban areas. However, the rate of adoption in rural areas may vary due to differences in road conditions and population density.

In terms of the relationship between autonomous driving and powertrains, EVs are considered to be the most compatible with autonomous driving due to their compatibility with software control. While hybrid vehicles will continue to play a role, the future widespread adoption of autonomous driving is expected to increase the proportion of EVs due to the integration of control and ease of maintenance. Gasoline-powered vehicles will gradually decline in the future, and the industry as a whole will see significant increases in demand in areas such as electrical and software development, sensors, and semiconductors, potentially significantly restructuring the entire automotive industry.

The slow progress of autonomous driving in Japan is due to factors such as high societal demand for safety, complex road environments, cautious legal system development, and infrastructure disparities between rural and urban areas. Additionally, clarifying the scope of responsibility in the event of an accident, improving communication infrastructure, and establishing a system for continuous data collection and improvement are also essential. Progress in autonomous driving could help alleviate labor shortages in the logistics and transportation sectors, but replacing everything with autonomous driving is difficult. Therefore, autonomous driving will likely play a complementary role in specific areas, particularly long-distance transportation and nighttime delivery.

The benefits of introducing autonomous driving include fewer traffic accidents, improved logistics efficiency, maintaining regional transportation, and expanding mobility opportunities for people with mobility restrictions. On the other hand, there are also anticipated disadvantages, such as risks in the event of system malfunction, cybersecurity issues, changes to employment in driving-related occupations, and disparities in adoption due to high costs. Given these factors, the introduction of autonomous driving is not just a technical challenge; it is a theme that will have an impact on the entire social structure, making gradual and sustained efforts essential.

Japan's autonomous driving market is expected to expand steadily in the future, backed by policy support and technological innovation. As adoption progresses from the commercial sector and spreads to passenger cars, the automotive industry is predicted to shift from being centered on hardware to being a multi-disciplinary industry that includes software and services. Advances in autonomous driving are expected to contribute to resolving social issues while shaping a new direction for Japan's mobility industry.

1. Introduction

In environments like aerospace, where space, weight, and thermal loads are unforgiving, conventional hardware solutions are often inadequate. This briefing analyzes two advanced board-level technologies—Flexible Printed Circuits (FPCs) and Copper Coin Printed Wiring Boards (PWBs)—engineered to provide robust performance, three-dimensional wiring, and superior thermal management under these extreme operational constraints.

2. Flexible Printed Circuit Boards (FPCs) for High-Reliability Applications

2.1. Overview and Core Characteristics

A Flexible Printed Circuit Board (FPC) is a circuit board made by applying a copper wire pattern to a thin, flexible insulating material. Unlike traditional rigid boards, FPCs offer distinct advantages in form factor and application.

The three primary characteristics of FPCs are:

• Flexibility and 3D Wiring: FPCs can be bent and folded, which allows for free arrangement within confined areas and enables complex three-dimensional wiring configurations.
• Thin and Lightweight: FPCs are extremely thin, typically 0.1 to 0.2 mm, and lightweight, weighing approximately one-fifth as much as traditional cables. This contributes directly to the miniaturization and weight reduction of electronic devices.
• Dynamic Movement: FPCs can be formed into specific shapes, such as a bellows, to accommodate dynamic movement, including repeated bending and extension. For applications involving simple, repeated flexion, they can be engineered to withstand over 100 million cycles.

2.2. Suitability for Harsh Environments

FPCs are highly suitable for use in harsh environments, such as space and aviation, where high reliability is a critical requirement. Their material composition is key to this durability. FPCs use a thin insulating material like polyimide, which provides excellent heat resistance (above 120°C), radiation resistance, and superior electrical insulation properties, making them robust enough for the rigors of space.

2.3. Case Study: The Ikaros Solar Sail

The history of FPCs dates back to the late 1960s, following the mass production of polyimide film, which led to their adoption by NASA for aerospace applications. The same fundamental material properties that made FPCs valuable for early space missions—namely polyimide's resilience—are precisely what enabled the success of ambitious modern missions decades later, demonstrating the technology's enduring relevance.

A significant application of this technology was the use of OKI's FPCs in the JAXA "Ikaros" small solar power sail demonstrator, launched in 2010. The FPC was chosen for this mission after being evaluated for its key attributes: being lightweight, heat-resistant, and radiation-resistant. In the Ikaros craft, a continuous 14-meter FPC was used as the wiring for thin-film solar cells and various sensors attached to the sail's surface. The mission was a success, marking the world's first successful demonstration of a solar power sail.

3. Copper Coin Printed Wiring Boards (PWBs) for Enhanced Thermal Management

3.1. Functional Principle

A Copper Coin Printed Wiring Board (PWB) is a product where a solid copper coin is embedded directly into the board to conduct heat away from electronic components. The primary function of the coin is to transfer thermal energy from a component on one side of the PWB to the backside, where it can be dissipated through direct contact with a chassis or heat sink. This method is particularly advantageous for components where heat cannot be dissipated from the top surface.

3.2. Innovation: The Convex Copper Coin

To improve thermal performance, a convex (凸型, totsugata) copper coin was developed. The purpose of this design is to increase the surface area on the heat dissipation side of the board, thereby improving the efficiency of heat transfer away from the component and into the chassis.

3.3. Manufacturing Challenge and Solution

The Challenge: The introduction of the convex coin presented a manufacturing challenge. The traditional method—using pressure to deform a cylindrical coin into a through-hole—is unsuitable for convex coins. The varying diameters of the convex shape result in uneven deformation under pressure. This non-uniform deformation prevents the formation of a secure mechanical interlock, compromising the coin's stability and thermal interface within the board.

The Developed Method: A new manufacturing process was developed to reliably secure the convex coins. This method involves the following steps:

1. Create two separate multi-layer board sections (e.g., layers L1-L4 and L5-L8).
2. Drill holes in each board section that correspond to the different diameters of the convex coin.
3. Stack the board sections with a layer of prepreg material placed between them.
4. Insert the convex copper coin into the aligned holes.
5. Laminate the entire assembly. During this process, the prepreg material's resin melts and flows into the gaps, encapsulating the coin. As the thermosetting resin cures during lamination, it forms a robust, void-free bond that mechanically locks the coin in place and ensures a stable thermal pathway.

This new method has been validated through reliability evaluations, including heat cycle tests, confirming sufficient durability for demanding applications. Its true ingenuity lies in its use of existing, space-qualified materials and processes—namely multi-layer lamination and prepreg resin—to solve a novel mechanical problem. This approach minimizes qualification risk by leveraging proven manufacturing infrastructure.

Laser processing is one method for cutting out (processing) the outer shape of an FPC. This laser processing has two main advantages compared to using a mold.

The cost of preparation (initial cost) is low
To process the outer shape of an FPC, there are two methods: using a dedicated mold called a "mold" and using a laser processing machine. When using a mold, it is necessary to create a special mold that matches the shape of the product. It costs money to create this mold (this is part of the initial cost). On the other hand, with laser processing, there is no need to prepare such a mold. You can simply prepare the shape you want to process as data on a computer. Therefore, there is a great advantage in that you can keep the initial preparation cost (initial cost) for making the product low because there is no cost to make a mold.

Easy to respond when you want to change the shape
In the initial stage of product development (prototype stage), it is often necessary to change the specifications, such as "I want to change the shape of this part a little more" after using the actual FPC. If you use a mold for processing, you must create a new mold from scratch to fit the new shape in order to change the shape. This takes time and money again. However, with laser processing, even if you want to change the shape, you can do so simply by editing the processing data on a computer. This has the advantage of being able to respond flexibly to specification changes quickly and without incurring large additional costs.

Because of these advantages, laser processing is a very effective method, especially when prototyping FPCs, as it reduces initial costs and also makes it easy to change the shape later. Laser processing takes longer to process than using a mold, so it is mainly used for small-scale production such as prototyping. Please choose the optimal processing method depending on the final specifications of the FPC and the quantity to be made.
