Ismertetés

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

LED indicator

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

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.

Switching element

ETX C

Slow-action switching contact

Contacts for guard locking: 2 positively driven, positively driven contacts 1 NO contact

Contacts for door monitoring: 1 NO contact

Auxiliary release

The auxiliary release on the front allows access to the machine in the event of a malfunction, e.g. a power failure. It is unlocked using a tool or a key. The auxiliary release must be secured against misuse (sealing, laking).

Escape release

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

Unlocking under load

This switch has an increased retention force. The retention force is the maximum force that may be applied to the actuator when the safety switch is locked so that the guard locking can still be unlocked.

Required accessories

Actuator is not included in the scope of delivery.
