Description
xThe Euchner MGBS-P-L1-AR-U-R-AEE-SH is a safety guard locking switch module incorporating two illuminated pushbuttons and an emergency stop function, operating on the closed-circuit current principle whereby guard locking is actuated by spring force and released when power is applied. It is designed for installation on hinged safety doors (DIN right configuration) and connects via an M23, 19-pin plug connector. With a locking force of up to 3900 N and an IP65 degree of protection when inserted and secured, it is suited to machine guarding applications where controlled access and reliable interlocking are required.
Key specifications
- Connection: 1 plug connector M23, 19-pin, RC18
- Operating temperature: with UB = 24 V DC -20 to 55 °C
- Material: Safety switch housing: Reinforced thermoplastic, Switch bracket: Die-cast zinc

| MGBS-L1 | Guard locking actuated by spring force and power-ON released (closed-circuit current principle). |
Lens Set
The color of the pushbuttons can be selected using the color cover set included (5 colors).
Escape Release
It is used for manual release of the guard locking without tools in an emergency. The inner door handle permits escape from the danger zone.
