KNX Type K Thermocouple Extension Wire – FEP Insulated, 0.2mm² 26AWG Ultra-Thin Grade

Product Overview

This KNX Type K thermocouple extension wire from Huona is a space-optimized, high-performance signal transmission solution for Type K temperature sensing systems, purpose-built for ultra-tight installation scenarios, high-density control cabinets, and miniature sensor assemblies. Constructed with KN (Alumel, Type K thermocouple negative leg) precision-calibrated alloy conductor, paired with matching KP (Chromel, positive leg) for complete circuit compatibility, and high-performance FEP fluoropolymer insulation, this wire delivers ultra-stable thermoelectric performance, exceptional chemical resistance, and industry-leading space efficiency. It is engineered for use in compact industrial equipment, embedded temperature monitoring, and high-density wiring layouts where traditional insulated wires cannot meet size requirements.

Core Specifications

Product Name: KNX Type K Thermocouple Extension Wire
Conductor Material: KN (Alumel, Type K thermocouple negative leg)
Insulation Material: FEP (Fluorinated Ethylene Propylene, black finish)
Standard Conductor Size: 26AWG (0.2mm² cross-section)
Wire Configuration: Single-conductor (KNX Alumel leg, matching KPX Chromel leg available as a matched pair)
Standard Outer Diameter: 1.2mm
Standard Length: 1000m/spool (custom cut lengths available)
Thermoelectric Performance:
- Accuracy Class: IEC Extension Grade 1
- Thermoelectric Power: Strictly calibrated to IEC Type K thermocouple standards
Operating Temperature Range: -50°C ~ 205°C (continuous use)
Standards Compliance: IEC 60584-3, GB/T 4989, RoHS 2.0, REACH

Key Differentiating Advantages

1. Ultra-Thin Design for High-Density Wiring

The 1.2mm outer diameter and 26AWG conductor enable 50% more wiring in the same space compared to standard 24AWG wires, making it ideal for high-density control cabinets, miniature thermocouple probes, and embedded sensor installations. It allows for more compact equipment design without compromising signal performance.

2. FEP Insulation for Balanced Performance & Processability

FEP insulation offers a perfect balance of high-temperature resistance, chemical inertness, and excellent processability. It maintains stable electrical performance from cryogenic temperatures down to -50°C up to 205°C, with excellent resistance to acids, alkalis, organic solvents, and ozone. It also features low smoke and zero halogen properties, making it suitable for enclosed industrial spaces.

3. Precision-Calibrated Conductor for Consistent Signal Transmission

The KN (Alumel) 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 KPX Chromel wire to form a complete, perfectly matched Type K extension circuit.

4. Superior Mechanical Durability & Flexibility

FEP insulation provides high tensile strength, abrasion resistance, and resistance to cracking under repeated bending. The wire maintains excellent flexibility for easy routing in tight spaces, around complex geometries, and in dynamic applications with constant movement.

5. High-Volume Production-Friendly Design

The long spool length and thin form factor reduce material waste in high-volume sensor manufacturing, while the FEP insulation allows for fast, clean stripping and termination. It is ideal for mass production of miniature thermocouple probes and compact temperature sensing equipment.
