Tankii Hot Sale Type K Extension Wire PVC Insulated 2×0.5mm Green Thermocouple Wire
Type K Thermocouple Extension Wire
PVC Insulated, 2×0.5mm Green Thermocouple Wire for reliable temperature signal transmission in industrial and laboratory applications.
Product Overview
Type K thermocouple extension wire from Tankii Alloy Material is a flexible, general-purpose signal transmission cable featuring Type K (Chromel/Alumel) conductors and green PVC insulation. Designed for low-to-medium temperature environments, it delivers stable thermoelectric performance up to 105℃ continuous / 120℃ short-term. Ideal for industrial control systems, HVAC, laboratory testing, and general-purpose temperature sensing.

- Conductor: 2×0.5mm diameter (tolerance: ±0.02mm)
- Insulation: PVC (green, IEC color for Type K)
- Chemical Composition: Positive (KP): Ni 89%/Cr 10%/Fe 1%; Negative (KN): Ni 95%/Al 2%/Mn 2%/Si 1%
- Insulation Material: Polyvinyl Chloride (PVC, 105℃ rating)
- Compliant Standards: IEC 60584-3, GB/T 4989-2013, ASTM E230, RoHS 2.0
- Manufacturer: Tankii Alloy Material, certified to ISO 9001 and IATF 16949
Key Advantages
Flexible & Easy Installation
High flexibility with minimum bending radius ≥5× cable diameter, suitable for tight installation spaces. Lightweight design ideal for portable testing equipment and long-distance signal extension.
