That 25 mm rating means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it's the right choice for point-of-operation guarding where smaller gaps aren't needed. The 1345 mm protective height covers a wide vertical zone, and with 66 beams at a 20 mm pitch, the resolution is fine enough to detect a hand but not so dense that alignment becomes a headache on longer runs. ## Where it fits on the line Operating range runs from 0.2 m up to 7.0 m, so it works for both tight machine guarding and wider access zones. The IP65 rating means the housings and optics withstand washdown — suitable for food-and-bev lines or any area where hoses are used. Blanking and muting functions are built in, which lets you configure fixed or floating blanking for workpiece pass-through and muting for conveyor-fed stations without an external controller. Listed as Active in production, so this isn't an obsolete or NRND part you'd need to chase through surplus channels.","metaTitle":"Omron F3SJ-B1345N25 Light Curtain, 25mm Hand Protection, 134","metaDescription":"Omron F3SJ-B1345N25 safety light curtain with 25mm detection capability, 1345mm protective height, 66 beams at 20mm pitch.
