Type K Thermocouple Extension Wire – PFA Insulated, 20AWG

Product Overview

This PFA-insulated Type K thermocouple extension wire from Huona is a dedicated signal transmission solution for Type K temperature sensors, designed to accurately transmit low-level thermoelectric signals from the sensing point to the control or measurement instrument. Manufactured with precision-matched KP/KN thermocouple alloy conductors and high-performance PFA fluoropolymer insulation, this wire offers excellent high-temperature resistance, electrical insulation, and chemical stability. It maintains consistent thermoelectric performance over long transmission distances, minimizing signal loss and measurement error, making it ideal for industrial process control, laboratory testing, and HVAC system temperature monitoring.

Core Specifications

Product Name: Type K Thermocouple Extension Wire
Conductor Material: KP (Chromel, positive leg, red) / KN (Alumel, negative leg, white)

Standard Conductor Size: 20AWG (0.519mm² cross-section)
Wire Configuration: 2-core twisted pair (red + white)
Standard Outer Diameter: 2.2mm
Standard Length: 100m/roll (custom cut lengths available)
Thermoelectric Performance:
- Accuracy Class: IEC Extension Grade
- Thermoelectric Power: Matched to Type K thermocouple standards
Operating Temperature Range: -60°C ~ 260°C (continuous use)
Standards Compliance: IEC 60584-3, GB/T 4989, RoHS 2.0, REACH

Key Differentiating Advantages

1. High-Precision Signal Transmission

The KP/KN conductor alloy is strictly calibrated to match Type K thermocouple standards, ensuring minimal signal deviation and accurate temperature reading transmission. The twisted pair design reduces electromagnetic interference (EMI), maintaining measurement accuracy even in industrial environments with electrical noise.

2. Superior PFA Insulation Performance

PFA insulation offers excellent high-temperature resistance (up to 260°C continuous use), far outperforming PVC or polyethylene insulations. It also features outstanding chemical resistance to acids, alkalis, and organic solvents, as well as low smoke and zero halogen properties, making it suitable for harsh industrial environments.

3. Excellent Mechanical Durability & Flexibility

The PFA insulation provides high tensile strength and abrasion resistance, while maintaining good flexibility for easy installation in tight spaces, conduits, or around complex geometries. It resists cracking under repeated bending and thermal cycling, ensuring long-term reliability.

4. Wide Operating Temperature Range

The wire operates reliably from cryogenic temperatures down to -60°C up to 260°C, covering a wide range of application scenarios from low-temperature refrigeration systems to high-temperature industrial ovens.

5. Easy Identification & Installation

The red/white color-coded insulation provides clear polarity identification, preventing connection errors during installation. The smooth PFA surface allows for easy stripping and termination, reducing installation time and improving work efficiency.
