What This Light Curtain Covers
The Omron F3SJ-A0295P30 is a 30 mm detection-capability safety light curtain from the F3SJ-A series, rated for hand and arm protection. Its 295 mm protective height and 12 beams at 25 mm pitch create a sensing field that catches a hand or arm reaching through the guarded opening before contact with moving machinery. The 30 mm detection capability means a 30 mm-diameter object triggers the output — that is the finger and hand protection threshold per IEC 61496-2, not a coarse presence sensor. Operating range spans 0.2 m to 9.0 m, so it fits both tight machine guarding and wider access zones on a production line.
Runs on 24 VDC, the standard safety-circuit supply in most panels, so no separate power rail is needed. IP65 rating — dust-tight and protected against water jets — means the sensor head and housing withstand washdown on food, beverage, or packaging lines without needing an additional enclosure. The blanking and muting functions built into this unit allow fixed or floating blanking to ignore stationary objects (like a fixture or conveyor frame) in the field, and muting to temporarily bypass the curtain during material pass-through without cycling power. These are hardware-configurable features on the F3SJ-A series, not add-on modules.
Deployment Context
Mounts to machine frames or stands via the standard F3SJ-A brackets; the slim 295 mm column fits into tight guarding envelopes on assembly stations, packaging machines, and robotic cells. IP65 lets it sit in the hazard zone without a separate enclosure, and the 24 VDC supply integrates directly with a safety PLC or safety relay. The 30 mm detection capability means it is certified for hand and arm protection per IEC 61496 — not for finger detection (14 mm) or body presence (50 mm+), so match it to the risk assessment accordingly.
