Type K Thermocouple Connectors

Type K Thermocouple Connectors
K Type Thermocouple Connectors are the most utilized design throughout industry, they accurately and securely transfer the wide temperature range of −330°F to 2460°F (−200°C to 1350°C) from Type K thermocouple probes and wire. Type K Miniature Male and Female Thermocouple Connector Set - Mating Pair
  • Temperature Accuracy is ensured with the contact pins being made from matching thermocouple alloys with nickel-chrome for the positive and nickel aluminum for the negative.
  • Temperature Operating range of the connector bodies is  -40 to 1200°F (-40 C to 650°C) although the specific range is significantly influenced by the connector body material selected. 
  • The Filter Search Tool on the Left of this page can quickly help find specific designs, or simply scroll down to browse the extensive offering of connectors.
  • Connector Body materials are typically thermoplastics, thermosets or ceramics
    • Thermoplastics are the most utilized design with temperature range of approximately -40 to 400°F plus (-40 to 200°C) and have a good level of mechanical durability. 
    • Thermoset materials are an excellent choice where the connector itself would be exposed to a continuous 500°F to 800°F (260°F to 425°Crange. Thermosets typically have a higher level of impact resistance than ceramics although lower than most thermoplastics.
    • Ceramics provide a -20 to 1200 °F (-29 to 650 °C) range and also provide the opportunity to be utilized in Vacuum applications. Ceramics are more susceptible to mechanical damage as compared to thermoplastic or thermoset designs. 
    • Sizes and Designs - the 2 basic sizes are male and female miniature connector utilizing flat pins and the larger standard round pin connector with with both using a rectangular body.
      • Specific Functional designs include connector with the ability to mount in control panels, on electronic circuit board, and within protections heads.
      • Other Unique applications include a 3 pin design minimizing electrical interference, 4 pins to support 2 thermocouple circuits and round connector bodies. 
    • Colored Coding - the most utilized connector color code for is Yellow for Type K ANSI (American National Standard Institute) and Green for IEC (International Electrotechnical Commission)
