KNX Type K Thermocouple Extension Wire – XLPE Insulated, 0.3mm² 24AWG

Product Overview

This KNX Type K thermocouple extension wire from Huona is a high-reliability, flame-retardant signal transmission solution for industrial Type K temperature sensing systems, purpose-built for high-density wiring, long-distance signal transmission, and harsh industrial environments. Constructed with KN (Alumel, negative leg) precision-calibrated thermocouple alloy conductor, paired with matching KP (Chromel, positive leg) for complete circuit compatibility, and high-performance XLPE (Cross-Linked Polyethylene) insulation, this wire delivers ultra-stable thermoelectric performance, excellent electrical insulation, and superior environmental resistance. It is optimized for use in industrial control cabinets, long-distance field wiring, and equipment internal wiring, where signal stability and flame safety are critical.

Key Differentiating Advantages

1. XLPE Insulation for Enhanced Safety & Performance

XLPE insulation offers superior high-temperature resistance, mechanical strength, and flame retardancy compared to standard PVC insulation. It maintains stable electrical performance up to 125°C, with excellent resistance to thermal aging, abrasion, and chemical corrosion, ensuring long-term reliability in industrial environments.

2. Ultra-Stable Signal Transmission for Long-Distance Runs

The precision-calibrated KN (Alumel) conductor ensures minimal signal deviation and accurate temperature reading transmission, even in long-distance installations up to several hundred meters. The consistent conductor resistance across the entire length eliminates measurement errors caused by signal attenuation.

3. High-Density Wiring Compatibility

The compact outer diameter allows for high-density wiring in control cabinets, cable trays, and tight spaces, making it ideal for use in complex industrial control systems. The flexible construction allows for easy routing around obstacles and tight bends, reducing installation time.

4. Excellent Environmental Resistance

XLPE insulation provides excellent resistance to moisture, ozone, and UV radiation, making it suitable for both indoor and outdoor installations. It also offers low smoke and zero halogen properties, making it compliant with industrial safety standards for enclosed spaces.

5. Cost-Effective for Bulk Industrial Deployments

The high roll length and durable construction make it ideal for large-scale industrial projects, reducing material waste and replacement costs. It is fully compatible with all standard Type K thermocouple sensors, connectors, and instrumentation, allowing seamless integration into existing systems.
