Thermorex TK-AA-02

Hermetic bimetalic temperature sensitive switch or cyclic operation device with automatic reset control.

THERMOREX TK-AA-02

This is a cyclic operating temperature sensitive device, which is intended to control the temperature between two particular values under normal operating conditions, automatically switching on or off the electrical circuit.This is hermatic version dedicated to military aplication. This thermostat can be built to either open or close its electrical contacts as the temperature increases. Once the temperature of the bimetal disc has returned to the specified reset temperature, the contacts will automatically return to their original state. Besides its variety of standard configurations the thermostat can also be customized to the specific technical needs of the customer, assuring maximum design flexibility and usage in broad range of temperature control applications for military and aerospace.
