The Omron F3SJ-A0860P25-TS is a Type 4 safety light curtain from the F3SJ-A series, designed for hand protection with a 25 mm detection capability — that is the smallest object diameter the curtain reliably catches, making it suitable for finger-protection-class applications per IEC 61496-1 where a 14 mm pitch would be needed for actual fingers. The 20 mm beam pitch and 43 beams create a protective field 860 mm high, sized for a single hazard zone on a conveyor infeed or a small machine access point. Operating range spans 0.2 m to 9.0 m, so it fits both tight guarding near the emitter and longer spans across a work cell. Blank and muting functions are built in — blanking lets you optically mask fixed obstructions (a part fixture passing through the field) without disabling the entire curtain, while muting temporarily suspends the safety output during a defined material-handling sequence. These are configuration-level features, not hardware options, so the same unit handles both standard guarding and automated guided vehicle or pallet-handling zones.
Deployment context — where this light curtain lives
Supply is 24 VDC, standard for safety circuits; the emitter and receiver pair draw from a single safety-rated power supply, and the outputs (OSSDs) connect directly to a safety PLC or safety relay.
