The Omron F3SJ-B1505P25 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 reliably detects a human finger or hand entering the protected zone — the standard threshold for hand safeguarding per IEC 61496. With 74 beams on a 20 mm pitch spanning a 1505 mm protective height, it guards a vertical area roughly 1.5 meters tall, suitable for press brakes, assembly stations, or robot cells where an operator reaches into the hazard zone. Operating range runs from 0.2 m to 7.0 m, so it works both in tight spaces near the machine frame and across wider access points.
Built-in production flexibility
Blanking and muting functions are built in. Blanking lets you disable specific beams to allow a fixed obstruction (like a fixture or conveyor rail) through the field without triggering a stop. Muting temporarily suspends the curtain during a non-hazardous part of the cycle — for example, when a pallet passes through the guarded opening. These are configurable via the controller, not a separate module, which keeps the wiring simple.
