Thermocouple Connectors


Flat-Pin Mini Male Connector	Flat-Pin Mini Female Connector	Round-Pin Male Connector	Round-Pin Female Connector

Simplify connecting your thermocouple to thermometers and control panels—these connectors give your thermocouple a plug-in connection. To attach them to your thermocouple, first remove the panel on these connectors to expose the terminals. Then insert your thermocouple wire leads, tighten the terminals, and reattach the panel.

Quick-Wire Thermocouple Connectors


	Male Connector	Female Connector

No need to take these connectors apart to wire them—just insert your wire leads and tighten the terminals to quickly give your thermocouple a plug-in connection. Choose a connector with the same thermocouple type as the thermocouple you’re attaching. You should also make sure the equipment you’re plugging these connectors into is also compatible with the same thermocouple type.
