Key Core Advantages
Clear Polarity & Type Identification
Standard color coding for sheath and insulation (blue for K/J, green for T) ensures easy identification of thermocouple type and polarity, reducing installation errors. Multi-core design supports multi-channel temperature measurement with individual pair shielding.
Excellent Anti-Interference Performance
Tinned copper braid shielding with ≥85% coverage effectively blocks EMI/RFI, ensuring stable signal transmission in high-noise industrial environments. Twisted pair conductor structure minimizes crosstalk between cores.
High-Temperature Resistance & Durability
FEP/PFA insulation withstands continuous operating temperatures up to 200℃, preventing insulation degradation. Robust outer sheath is oil-resistant, abrasion-resistant, and flame-retardant (VW-1).
Flexible Installation & Compatibility
Stranded conductors and thin insulation provide high flexibility for installation in tight spaces and cable trays. Compatible with all standard thermocouple sensors, temperature controllers, data loggers, and PLC systems.
Stable Thermoelectric Performance
Meets Class 1 accuracy for extension cables, ensuring minimal signal drift and accurate temperature measurement. High-purity alloy conductors ensure low electrical resistance, reducing signal loss over long distances.
