1/2″ switches (R25 series)

Data sheet

You will receive a complete overview of all variations in connection with all the technical data in the following data sheet:

R25, R26, R35, R36

Switches of the R series are extremely robust switches with universal characteristics: they can be used as temperature monitors and controllers, current-capable up to 16 A, specifically adjustable hysteresis and low tolerances up to ± 3K.

The plastic housing, the floor and the fastening are tension-free. The heat is applied directly to the thermo-bimetallic snap-disc via the contact surface (bottom), and thus allows a very rapid reaction. The connections vary in dimensions and mounting angles (0 - 90°).

Types R25 and R26 are automatically resetting, whereas types R35 and R36 are manual-resetting switches.
