Easy Installation
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.
