Description
Type K Thermocouple Wire (Solid, 20AWG/21SWG, Fiberglass Insulation, 800℃)
Type K thermocouple wire from Huona New Material is a high-temperature sensor wire designed for direct connection to Type K thermocouple sensors. Featuring solid 20AWG/21SWG conductors, braided fiberglass insulation, and excellent thermal stability, it delivers reliable thermoelectric performance up to 800℃. Ideal for industrial furnaces, kilns, and high-temperature process monitoring.
Standard Designations & Core Specifications
  • Model: K Type (Thermocouple Grade)
  • Conductor Structure: 2-core solid (single solid wire per core, twisted pair)
  • Conductor Gauge: 20AWG (equivalent to 21SWG)
  • Conductor Diameter: ~0.81mm (20AWG solid)
  • Conductor Material: Positive (KP): Chromel (Ni 90% / Cr 10%); Negative (KN): Alumel (Ni 95% / Al 2% / Mn 2% / Si 1%)
  • Insulation Material: High-temperature braided fiberglass (rated to 800℃)
  • Color Coding: ANSI standard - Yellow (KP) / Red (KN)
  • Compliant Standards: IEC 60584-2, ASTM E230, ANSI MC96.1, GB/T 4989, RoHS 2.0
Key Advantages
Ultra-High Temperature Resistance
Braided fiberglass insulation withstands continuous operating temperatures up to 800℃, with short-term tolerance to 850℃. Insulation does not melt or degrade at high temperatures, ensuring long-term reliability in extreme heat environments.
Stable Thermoelectric Performance
Meets Class 1 accuracy standards with minimal signal drift. 20AWG solid conductors provide low electrical resistance and consistent signal transmission, reducing signal loss over distances.
ANSI-Standard Polarity Identification
ANSI-standard yellow (positive) / red (negative) color coding ensures clear polarity identification, eliminating installation errors and simplifying maintenance.
Robust Mechanical Strength
Braided fiberglass construction provides excellent abrasion resistance and mechanical protection. Twisted pair design minimizes electromagnetic interference and enhances signal integrity.
Flexible Installation & Compatibility
Highly flexible design suitable for routing in tight spaces. Compatible with all Type K thermocouple sensors and standard high-temperature temperature controllers.
