What the ratings mean for fit
The Omron F3SJ-B0945P25 is a Type 4 safety light curtain from the F3SJ-B series, rated for hand protection with a 25 mm detection capability. That 25 mm figure means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1, not just hand or body detection. The 20 mm beam pitch and 46 beams give it a 945 mm protective height, sized for guarding a vertical opening on a packaging machine or assembly station. Operating range spans 0.2 m to 7.0 m, so it works both in tight reach-in applications and across wider access points. The 24 VDC supply is standard for safety circuits, and the IP65 rating means the sensor body and optics withstand washdown — suitable for food-and-bev lines where hose-down cleaning is routine.
Deployment context
Mounts with standard brackets to machine frames or guarding structures. The blanking and muting functions let it ignore fixed obstructions (like a conveyor frame) or temporarily bypass during a material pass-through — both essential for production lines that can't stop for every cycle. Rated for -10°C to 55°C operating temperature, so it handles unheated plant floors in temperate climates.
