What this light curtain does on the line
The Omron F3SJ-B0225P25 is a Type 4 safety light curtain from the F3SJ-B series, built for hand protection at the hazard zone. The 25 mm detection capability and 20 mm beam pitch mean it catches fingers reaching into danger — that's finger-protection class per IEC 61496-1, so it's the right call for guarding press brakes, assembly stations, or robot cells where an operator's hands need to stay clear. With 10 beams spread across a 225 mm protective height, this curtain covers a compact vertical zone. The 0.2 m to 7.0 m operating range gives you flexibility to mount it close to the hazard or back a few meters, depending on the machine layout.
Tough enough for the route
Rated IP65 — dust-tight and protected against water jets — so it'll survive washdown cycles and the grit you find out on the plant floor. Runs on 24 VDC, which is standard for safety circuits. The blanking and muting functions built into this model let you program out fixed obstructions (like a machine frame) or temporarily bypass the curtain during a material feed cycle — both handled internally without needing an external controller.
