No special tooling is required for installation. Just drill or punch a round hole in your panel and tighten the supplied nut. Ideal for single-circuit applications where the connector must blend with existing instrumentation. Thermocouple circuits can be added to existing panels with only minimal interruption of operations. A choice of either square or round face is available to match the design lines of your installation. Thermocouple grade alloys used to form the contacts preserve the accuracy of the circuit even in changing ambient temperatures. An optional Front Mount Kit is also available to mount the connectors to a panel from the front. It includes screws, bushings and a Dust Plug.

Examples of pricing for popular models is referenced in the 'To Order' box. Use the 'Part Number Builder' below to get pricing for all available models.

Square face RMJ & RSJ connectors will not be available after December 31st, 2018. Please consider buying our round face RMJ & RSJ, or contact sales or our Temperature Engineering department for a suitable replacement.
