Safety switch STM

Actuating head made of plastic
Auxiliary release on the front

Description

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Solenoid operating voltage

AC/DC 24 V +10%, -15%

Guard locking type

STM1	Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid.

Switching element
