The Omron F3SJ-A2100P25-TS is a Type 4 safety light curtain from the F3SJ-A series, designed for hand protection per IEC 61496. Its 25 mm detection capability means it catches fingers reaching into a hazard zone — that's the spec that decides whether it fits your guarding application. With 105 beams at 20 mm pitch, it covers a 2100 mm protective height, so it's sized for tall access openings like conveyor in-feeds or robot cell gates. Operating range runs from 0.2 m to 7.0 m, giving you flexibility to mount the emitter and receiver across a work cell aisle or closer to the machine frame.
Deployment context
Rated IP65 — dust-tight and protected against water jets — so it holds up on washdown lines in food processing or in dusty assembly areas. The 24 VDC supply is standard for safety circuits; you can drop it into a 24 V safety relay or safety PLC output without a separate power supply. Blanking and muting functions are built in, which means you can teach out fixed obstructions (like a machine frame member crossing the beam) or let a pallet pass through without tripping the stop — useful on automated conveyor lines where product needs to interrupt the field temporarily.
