Description

Approach direction

Horizontal

Can be adjusted in 90° steps

Guard locking principle

closed-circuit current (power to unlock): In a safety guard with guard locking according to the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with current. The guard is unlocked by means of magnetic force. This is also referred to as mechanical guard locking.

Protective plate for switch head

Makes tampering with the switch more difficult.

LED indicator

The switch has two freely assignable LED indicators (red and green).

Switching element

SK

2131

Slow-action switching contact

Contacts for door monitoring: 2 positively driven, positively driven contacts 1 NO contact

ÜK

3131

Slow-action switching contact

Contacts for guard locking: 2 positively driven, positively driven contacts 2 NO contacts

Escape release

This is used for manual release of guard locking from the danger zone without tools.

Emergency release

The emergency unlocking on the front is used to unlock the guard locking without tools in the event of danger. Unblocking and restoring readiness for operation requires an effort comparable to a repair. A sealing can be attached to prevent tampering.

Required accessories

Actuator is not included in the scope of delivery.
