Ismertetés

Approach direction

Horizontal and vertical

Can be adjusted in 90° steps

Guard locking principle

Operating current (power to lock): In the case of a safety guard with guard locking according to the open-circuit current principle, the safety guard is locked until the power supply to the guard locking solenoid is break-before-make. The guard is unlocked by spring force. This is also referred to as electrical guard locking.

LED indicator

The LED indicator illuminates when voltage is applied to the guard locking solenoid.

Switching element

2422

Slow-action switching contact

Contacts for guard locking: 2 positively driven, positively driven contacts

Contacts for door monitoring: 1 positively driven, positively driven contact 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).

Scope of delivery

Cable gland included in the scope of delivery.
