Mechanical temperature switch NC20-2 series

Principle structure

The NC20-2 series adopts the principle of bimetallic strips. When the temperature reaches the set value, the end of the bimetallic strip wound into a circular bending shape is heated and expanded to trigger the built-in mechanical device, and the switch is activated.

Product Features

All parts of NC20-2 in contact with the medium are made of brass material
There are three types of interface threads available: G1/4, G1/2, and M20 × 1.5
