When any object interrupts the beams, the curtain sends a stop signal to the machine safety circuit, protecting personnel from injury.
As a safety light curtain, the key rating is the detection capability and resolution, which determines what size object the curtain catches. The F3SJ-A1265P20-01TS is designed for point-of-operation guarding where a hand or finger entering the hazard zone must trigger an immediate stop. The 1265 mm protected height and 20 mm resolution mean it detects objects as small as 20 mm — sufficient for hand detection per IEC 61496-1 finger-protection class. The P20 suffix indicates the beam pitch and resolution configuration. Mounting brackets and alignment aids are typically required for installation; the curtain connects to a safety controller or safety relay via its M12 connector.
Deployment Context
This safety light curtain is deployed on assembly lines, packaging machines, press brakes, and robotic cells where personnel access to the hazard zone must be monitored. The emitter and receiver mount on opposing sides of the guarded opening, creating a protective field. The Bulk package indicates the unit ships as a single component without accessory kits — order mounting brackets, cables, and alignment tools separately if not already in the BOM.
