KPX Type K Thermocouple Extension Wire – High-Grade PVC Insulated, 0.5mm² 20AWG General-Purpose Grade


Product Overview


This KPX Type K thermocouple extension wire from Huona is a cost-effective, high-reliability signal transmission solution for general industrial Type K temperature sensing systems, purpose-built for bulk industrial projects, building automation, and standard equipment internal wiring. Constructed with KP (Chromel, Type K thermocouple positive leg) precision-calibrated alloy conductor, paired with matching KN (Alumel, negative leg) for complete circuit compatibility, and high-grade flame-retardant PVC insulation, this wire delivers consistent thermoelectric performance, excellent mechanical durability, and outstanding value for large-scale deployments. It is engineered for use in general industrial control systems, HVAC projects, and equipment manufacturing, where balanced performance and cost efficiency are critical.

Key Differentiating Advantages


1. Cost-Effective for Large-Scale Bulk Deployments


This general-purpose grade offers an optimal balance of performance and cost, making it ideal for large-scale industrial projects, building automation systems, and high-volume equipment manufacturing. The 1000m long spool length reduces material waste and lowers per-unit installation costs, perfect for bulk procurement.

2. Flame-Retardant PVC Insulation for Enhanced Safety


The high-grade flame-retardant PVC insulation meets general industrial safety standards, providing excellent flame resistance, self-extinguishing properties, and good resistance to abrasion, moisture, and mild chemical exposure. It ensures long-term reliability in general indoor and sheltered industrial environments.

3. Precision-Calibrated Conductor for Stable Signal Transmission


The KP (Chromel) conductor is manufactured with strict alloy composition control, ensuring consistent thermoelectric performance and accurate temperature reading transmission. The wire is paired with matching KNX Alumel wire to form a perfectly matched Type K extension circuit, eliminating measurement errors caused by conductor mismatch.

4. Easy Installation & High Visibility


The bright red insulation provides high visibility for easy identification in complex wiring systems, preventing connection errors during installation. The smooth PVC surface allows for fast, clean stripping and termination, reducing installation time and labor costs for large projects.

5. Wide Compatibility with Standard Systems


This wire is fully compatible with all standard Type K thermocouple sensors, connectors, and instrumentation, allowing seamless integration into new or existing temperature monitoring systems. It is suitable for a wide range of general-purpose applications, from HVAC systems to industrial machinery internal wiring.
