Product Description
Type K Thermocouple Mini Connector (Plug & Socket Set, Green, 200°C)
Product Overview
Type K thermocouple mini connector (as shown) from Huona New Material is a precision-molded plug-and-socket assembly designed for Type K (Chromel/Alumel) thermocouple signal connection. Featuring a heat-resistant green thermoset plastic housing and nickel-chromium/nickel-aluminum alloy contact pins, it ensures stable, low-resistance signal transmission up to 200℃ continuous / 220℃ short-term. Ideal for industrial temperature testing, HVAC, food processing, and laboratory use, it offers secure screw termination, IEC color coding, and reliable mating performance.
Standard Designations & Core Material Foundation
- Thermocouple Type: Type K (Chromel/Alumel; IEC 60584-2)
- Connector Type: Mini plug (male) + socket (female) set
- Housing Material: Heat-resistant thermoset plastic (green, IEC color for Type K)
- Contact Pins: Nickel-chromium (KP) / Nickel-aluminum (KN) alloy (matching Type K thermocouple material)
- Termination: Screw clamp (for 0.35–1.0mm diameter conductors)
- Operating Temperature: -20℃ to +200℃ (continuous); up to 220℃ (short-term)
- Compliant Standards: IEC 60584-3, ASTM E230, RoHS 2.0
- Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949
Key Core Advantages (Centered on Type K & Mini Design)
1. Material-Matched Signal Integrity
- Alloy Contact Pins: Nickel-chromium/nickel-aluminum pins match Type K thermocouple composition, minimizing thermal EMF error and ensuring accurate signal transmission.
- Low Contact Resistance: Precision-machined pins provide stable, low-resistance connection (<5mΩ), critical for reliable temperature measurement.
2. High-Temperature Housing & Durability
- Heat-Resistant Plastic: Green thermoset housing withstands 200℃ continuous operation, with no deformation or insulation breakdown in high-temperature industrial environments.
- Secure Mating: Positive locking design prevents accidental disconnection, ensuring reliable performance in vibration-prone applications (e.g., furnaces, automotive testing).
3. Easy Termination & Compatibility
- Screw Clamp Termination: Tool-free screw terminals accommodate 0.35–1.0mm diameter thermocouple wires, enabling fast, secure field termination.
- IEC Color Coding: Green housing (Type K) eliminates wiring errors, ensuring universal compatibility with Type K thermocouple probes and instruments.
