Guard locking type

MGB-L1…The locking arm is held in the locked position by spring force and is unlocked by solenoid force (closed-circuit current principle, mechanically locked).

Door hinge

A mechanical door stop is permanently integrated into the evaluation module of the MGB. A marking on the stop makes adjustment easier.

LED indicator

The LED indicator indicates all important system and status information.

Monitoring outputs

ODON when the door is closed
OTBolt tongue inserted into the evaluation module
OLGuard locking solenoid in locked position
OIDiagnostics; there is a fault


S11 NO contact, illuminated

Lens set

The color of the pushbuttons can be selected using the color cover set included (5 colors). Item no.: 120344 (see Accessories)
