Description
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
| OD | ON when the door is closed | 
| OT | Bolt tongue inserted into the evaluation module | 
| OL | Guard locking solenoid in locked position | 
| OI | Diagnostics; there is a fault | 
Emergency stop device
| S1 | 2 positively driven contacts and 1 NO contact (e.g. monitoring contact), emergency stop with turn-to-reset, not illuminated | 
Pushbuttons
| S2 | 1 NO contact, illuminated | 
| S3 | 1 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)
Adhesive labels
Devices with adhesive labels have pre-formed recesses. The adhesive labels enclosed (standard size 12.5 x 27 mm) can be affixed in these recesses.
