Standard Size Thermocouple Connectors

Standard Size Thermocouple Connectors are approximately 2 times the length, width and thickness of miniature thermocouple connectors along with having round thermocouple pins as compared to the flat pins utilized on the mini connectors. 

• 9 Types of Thermocouple Connector Calibrations or thermocouple types
• J, K, T, E, and N calibrations represent the most commonly used designs, sometimes referred as Base Metal Thermocouples.
• Type C, R/S, U (B) thermocouples are utilized in much more specific, and many times higher temperature ranges or applications
• Connector Bodies are available in 4 different materials providing a range from -40 F to 1200 F (-40 C to 650 C)
• Thermoplastics - Most utilized material and a temperature range of -40 to 400°F plus (-40 to 200°C)  with a good level of mechanical durability.
• Thermosets - for a continuous 500°F to 800°F (260°F to 425°C) range. Some connectors made from thermosets can crack more readily then the thermoplastic connector design, although the thermoset has a higher level of impact resistance as compared to ceramics.
• High Temperature Thermosets - can operate at 800°F (425°C) continuously with intermittent temperature capabilities to 1000°F (540°C). 
• Ceramics with capabilities in the -20 to 1200 °F (-29 to 650 °C) range. Can be utilized in Vacuum applications with very limited potential of outgassing or contamination. Ceramic connectors are more susceptible to mechanical damage as compared to thermoplastic or thermoset designs.
• Connector Designs include male plugs and female jacks or sockets in 2, 3 and 4 Pin configurations. 
• 2 Pins is the most commonly used design and support 1 thermocouple circuit.
• A 3 Pin design is 1 thermocouple circuit with the 3rd pin providing a Grounding Capability to minimize electrical interference
• Dual or 4 pin thermocouple connectors supports 2 thermocouple circuits
