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.
Key Ratings and What They Mean for Fit
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. Operating temperature from -10°C to 55°C covers heated plants and unconditioned warehouse environments. 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.
