The 25 mm resolution means it catches a hand or finger reaching into the hazard zone (finger-protection class per IEC 61496-1), not just a full body. It ships in a Bulk package, which for this class usually means the emitter and receiver pair, cabling, and mounting brackets are packed separately for field assembly.
Deployment context
This light curtain guards a hazard zone — typically a press brake, robot cell, or packaging machine entry point. The 25 mm resolution and 1105 mm height suit it for hand and finger detection at a reach-in opening. Mount the emitter and receiver on rigid uprights, aligned within the specified optical window; the control unit (sold separately) handles the OSSD outputs to the safety PLC or safety relay. Cable routing should keep the sensor leads away from VFD and motor power cables — is the signal clean? That depends on the shield termination at the control end.
