What are Miniature Thermocouple Connectors?

Miniature thermocouple connectors are compact, two-pin plugs and jacks used to link temperature sensors to instrumentation. They feature two flat, polarized pins to prevent incorrect wiring, which are made of matching thermocouple alloys to prevent signal errors. To avoid confusion, connector bodies can withstand temperatures up to 392°F (200°C), are color-coded based on the calibration type to ensure the right connector is matched with the proper thermocouple. The miniature thermocouple connectors are smaller in size compared to standard thermocouple connectors to accommodate smaller wire sizes than 24 AWG.
