• Locking module (order handle module separately)
• Adjustable door hinge, factory setting: right
• Series connection possible (up to 20 AR devices in series)
• Short circuit monitoring
• Two safety outputs (semiconductor outputs)
• Up to category 4/PL e according to EN ISO 13849-1

Door hinge The door hinge can be changed. Each handle module is unique. The locking module detects only handle modules that have been taught in. Additional handle modules can be taught in. Only the last handle module taught in is detected. Guard locking type

MGBS-L1

Guard locking actuated by spring force applied and power-ON released (closed-circuit current principle)

Lens set The color of the pushbutton can be selected using the lens set included (five colors). Escape release Is used for the manual release of the guard locking without tools. The inner door handle permits escape from the danger zone. Connector assignment
