Product Description
KPX Type K Thermocouple Extension Wire – Silicone Rubber Insulated, 0.35mm² 23AWG
Product Overview
This KPX Type K thermocouple extension wire from Huona is a high-flexibility, wide-temperature signal transmission solution for industrial Type K temperature sensing systems, purpose-built for dynamic installation scenarios, high-vibration environments, and extreme temperature operating conditions. Constructed with KP (Chromel, Type K thermocouple positive leg) precision-calibrated alloy conductor, paired with matching KN (Alumel, negative leg) for complete circuit compatibility, and high-performance silicone rubber insulation, this wire delivers ultra-stable thermoelectric performance, exceptional mechanical flexibility, and industry-leading wide-temperature adaptability. It is engineered for use in moving equipment, high-temperature field wiring, and dynamic industrial applications where rigid insulated wires cannot meet performance requirements.

Key Differentiating Advantages
1. Ultra-High Flexibility for Dynamic Installation
The high-performance silicone rubber insulation offers exceptional flexibility, with a minimum bending radius as low as 2.5× cable diameter, making it ideal for applications requiring repeated flexing, movement in cable chains, or installation in tight, curved spaces. It resists cracking under thousands of flex cycles, ensuring consistent performance in dynamic industrial environments.
2. Wide-Temperature Performance for Extreme Environments
This wire maintains stable electrical and mechanical properties from cryogenic temperatures down to -65°C up to 260°C, outperforming PVC, XLPE, and even many fluoropolymer insulated wires in extreme temperature scenarios. It is perfectly suited for use in high-temperature industrial ovens, low-temperature refrigeration systems, and outdoor field installations with large temperature fluctuations.
3. Precision-Calibrated Conductor for Accurate Signal Transmission
The KP (Chromel) conductor is manufactured with strict alloy composition control, ensuring minimal thermoelectric drift and accurate temperature reading transmission over long distances. The wire is paired with matching KNX Alumel wire to form a perfectly matched Type K extension circuit, eliminating measurement errors caused by conductor mismatch.
4. Superior Resistance to Environmental Stress
The silicone rubber insulation provides excellent resistance to ozone, UV radiation, moisture, and mild chemical exposure, ensuring long-term reliability in outdoor and industrial environments. It also features high tear strength and abrasion resistance, withstanding mechanical stress during installation and operation.
5. High-Volume Production & Field-Friendly Design
The long spool length and flexible construction reduce material waste and installation time in high-volume projects, while the bright red insulation provides high visibility for easy identification in complex wiring systems. It is ideal for use in industrial machinery, mobile equipment, and field-installed temperature monitoring systems.
