Açıklama

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

Power to unlock: On a guard with guard locking based on the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with power. Unlocking is by solenoid force. The term mechanical guard locking is also used.

Switching element

ETX B

Slow-action switching contact

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

Contacts for door monitoring: 1 NC contact

Auxiliary release

The auxiliary release on the front makes it possible to access the machine if there is a malfunction, e.g. a power failure. Unlocking is performed using a tool or a key. The auxiliary release must be protected against misuse (sealing, lacquer).

Unlocking under load

This switch possesses increased retention force. The retention force is the maximum force that is allowed to be applied to the actuator with the safety switch in the locked state so that the guard locking cannot be unlocked.

Accessories required

Actuator is not included.
