The Omron F3SJ-B1265P25 is a Type 4 safety light curtain from the F3SJ-B series, designed for hand protection with a 25 mm detection capability. Its 1265 mm protective height and 62 beams at a 20 mm pitch cover a vertical zone that catches a hand or arm reaching into a hazard area before the machine can cycle — that is the finger-protection class per IEC 61496-1, though here sized for hand-level guarding. The unit operates on a 24 VDC supply and has an operating range of 0.2 m to 7.0 m, so it works both for close-in access guarding and for longer perimeter setups up to 7 meters between emitter and receiver.
Key features for the guarding application
The F3SJ-B1265P25 includes blanking and muting functions, which means you can program fixed or floating blanking to ignore stationary objects (like a fixture or conveyor frame) within the field, and muting to temporarily bypass the curtain during a material pass-through cycle. These are not gimmicks — they are what let you use a single light curtain on a station with both manual access and automated material flow without false trips. The IP65 rating (dust tight and protected against water jets) means the emitter and receiver housings tolerate washdown environments, so this curtain is suitable for food-and-bev lines or any area that gets hosed down between shifts.
