The Omron F3SJ-A0620P25-TS is a Type 4 safety light curtain from the F3SJ-A series, rated for hand protection with a 25 mm detection capability. That 25 mm figure means it catches fingers and hands reaching into a hazard zone — the standard finger-protection class per IEC 61496-1. The 20 mm beam pitch and 31 beams give it a 620 mm protective height, covering a typical vertical access point on a machine guard. Operating range spans 0.2 m to 9.0 m, so it works both in tight spaces near the hazard and across wider access openings. The 24 VDC supply and IP65 rating mean it handles washdown environments — suitable for food-and-bev lines or assembly areas where hosing down the guard is routine.
Built-in blanking and muting
This unit includes blanking and muting function as standard features. Blanking lets you disable specific beams to allow fixed obstructions (like a machine frame) in the field without triggering a stop. Muting temporarily suspends the safety output during a defined material pass cycle — common on conveyor infeed stations where a pallet needs to break the beam without stopping the line.
The IP65 and 25 mm detection specs confirm fit for most point-of-operation guarding applications that call for hand protection in wet environments.
