Ismertetés
Version TWIN
The switch has two actuating heads. They enable two movable guards to be secured at the same time.
Approach direction

Horizontal and vertical
Can be adjusted in 90° steps
Increased overtravel for horizontal approach direction
If increased play is required when the door is closed, an actuator with overtravel is available. With this actuator the door can move slightly in the actuating direction when closed. This is important, for example, if safety doors have a rubber end stop. Using an actuator with overtravel, the continuous pressure from the compressed rubber can be reduced. In this way the load is reduced on the switch head and the door mechanism.
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
2131 | Slow-action switching contact |
Contacts for guard locking: 2 positively driven contacts | |
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).
Auxiliary key release
Additional lock on the switch head. Same function as auxiliary release. The position of the mechanical key release is displayed in the viewing window.
Scope of delivery
Two keys for mechanical key release are included in the scope of delivery.
Accessories required
Actuator is not included.
