The Omron F3SG-4SRB2280-25 is a Type 4 safety light curtain from the F3SG-SR series, built 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 — so it suits press brakes, assembly stations, and robotic cells where operators reach close to the danger point. The 2280 mm protective height and 114 beams at 20 mm pitch cover a tall access opening in a single emitter-receiver pair, eliminating the need to stack multiple curtains. Operating range spans 0.3 m to 20.0 m, which gives flexibility for both tight machine guarding and wider perimeter setups. Runs on 24 VDC, rated for -30°C to 55°C ambient, so it works in unheated factory bays or cold-chain packaging lines without derating. The IP65/IP67/IP67G ingress rating means the sensor body and optics withstand washdown — suitable for food-and-bev lines where high-pressure spray cleaning is routine.
Integration notes
Blanking and muting functions are built in — no separate controller module required for those features. Blanking lets you optically mask fixed obstructions (like a machine frame) within the field; muting temporarily suspends the curtain during a material pass, which is standard for conveyor-fed presses. The 114-beam count and 20 mm pitch mean the controller processes a high-resolution field. Verify that your safety PLC or relay has the I/O count and response time to handle the OSSD outputs at the required SIL/PL level. The 24 VDC supply should be a dedicated safety-rated power source, not the general control bus.
