The safety switch is available in different models. The following is an overview of
unique features of the models:
• One cable with M12 plug connector (5-pin)
• One cable with M12 plug connector (8-pin)
Locking Principle
Power to Lock Principle
• Lock locking device: voltage at locking device input
• Unlock locking function: no voltage at locking device input
If voltage is interrupted, the locking device is unlocked and the protective device
can be opened immediately.
The locking device is not monitored, which means that the safety switch does not
check whether the anchor plate is applied to the solenoid.
Item Description
1 Anchor plate
2 Protective cap
3 Actuator surface
ATTENTION: Hazard due to lack of effectiveness of the protective device.
If a voltage drop occurs, the locking device unlocks regardless of whether the
dangerous state of the machine has ended.
• Do not use the safety switch in applications where the dangerous state cannot
be ended immediately (stopping/run-down time).
