Sensor Pro SIN M Safety Switches (0849.1)

FUNCTION of SAFETY SWITCHES

The mechanical safety switches in the SIN series are suitable for the secure locking (guard locking) of safety doors until a hazardous machine process has ended.
The safety switches have two independent contact blocks which reflect the position of the actuator on the one hand and the
position of the guard locking on the other.  The release of the entry or the shutdown of the machine in case of danger is done by the evaluation of the contact blocks by means of a suitable basic device of the safe RELAY series or one of the safety systems samos® or samos® PRO.

SPRING-ACTUATED LOCKING

The safety switch on the guard is locked automatically when the actuator reaches its end position.
The guard is unlocked by applying a current to the internal electromagnets in the safety switch.

MAGNET-ACTUATED LOCKING

The safety switch on the safety guard is locked by energizing the internal electromagnet when the actuator reaches its end position.
If the internal electromagnet is de-energized, the guard control is unlocked and the guard can be opened
