When any beam is interrupted, the controller signals a stop to the guarded machine's hazardous motion. This is the core component for point-of-operation safeguarding on presses, assembly stations, and robotic cells where an operator needs access but must be protected from reaching into a hazard zone.
Deployment Context
As a safety light curtain, this part mounts at the point of entry to a guarded zone — typically on a machine frame or standoff brackets. The emitter and receiver columns align across the opening; the control unit (sold separately) handles the OSSD outputs and interface to the safety relay or safety PLC. Bulk packaging means the unit ships as a single item, not in a multi-pack or reel. For panel integration, the controller mounts on DIN rail inside the control cabinet; the light curtain columns themselves are field-mounted and cabled back.
