Fukuden offers the “K-HVVF Series,” a line of flat sheathed thermocouple cables featuring heat-resistant vinyl insulation and a heat-resistant vinyl outer sheath. This product is a sheathed thermocouple designed for simple temperature measurement; by connecting it directly to a temperature controller, it enables straightforward temperature measurement using the sensor alone. As a general-purpose standard type with excellent moisture and water resistance, it is widely used for temperature measurement in fixed wiring applications.
This product has a continuous operating temperature of 80°C and is well-suited for environments where the measurement temperature is low and protection against moisture and humidity is required. Fukuden’s lineup of sheathing materials includes glass braiding (heat resistance: 200°C, no water resistance) and fluororesin (heat resistance: 200°C, water resistance), among others. Among these, the “K-HVVF”—a heat-resistant vinyl specification—excels in applications requiring reliable waterproofing and moisture resistance in the low- to medium-temperature range. Conductor specifications include four types with nominal cross-sectional areas of 0.03 SQ (1/0.2 mm), 0.08 SQ (1/0.32 mm), 0.33 SQ (1/0.65 mm), 0.75 SQ (1/1.0 mm), and the finished outer dimensions of the flat-shaped cables range from approximately 1.2 mm × 1.8 mm to approximately 2.8 mm × 4.6 mm. In terms of electrical characteristics, the insulation resistance is guaranteed to be 40 MΩ-km or higher (0.03 SQ) or 50 MΩ-km or higher, and the product passes a withstand voltage test of 500 V DC/min or 500 V AC/min. It also complies with JIS C 1602 and meets RoHS 2 (10 substances) requirements.
The primary applications include general temperature measurement and simple measurements in fixed wiring installations. For color identification, in addition to the old JIS color specification—with a blue sheath and red and white insulation—the new JIS color specification, featuring a green sheath and green and white insulation, is also available. Furthermore, for environments requiring noise countermeasures, we offer shielded versions manufactured to order.
Fukuden’s “K-HVVF Series” is a highly reliable sheathed thermocouple that offers stable electrical characteristics and a flexible selection range for low- to medium-temperature temperature measurement applications requiring moisture and water resistance. We sell them in lengths of 1 meter or more, in increments of 1 meter. The standard delivery time is approximately one week. The product shown in the image is the K-HVVF 1P×1/0.65 Blue.
