The Omron F3SJ-A1620P30 is a type-4 safety light curtain from the F3SJ-A series, rated for hand and arm detection. Its 30 mm detection capability means it resolves a 30 mm object anywhere in the protected field — the standard finger/hand-protection threshold per IEC 61496-2. The 1620 mm protective height and 65 beams at 25 mm pitch cover a full reach zone for a standing operator, with an operating range of 0.2 m to 9.0 m, so it fits both tight machine guarding and wider access areas.
Deployment context
IP65 rating means the emitter and receiver housings tolerate washdown and airborne dust — suitable for food processing, packaging lines, or machining cells where coolant mist and hose-down cleaning are routine. The 24 VDC supply is standard for safety circuits; blanking and muting functions let the curtain ignore fixed obstructions (e.g., a conveyor frame) and automatically suspend guarding during a pallet pass-through, which avoids nuisance trips that slow production.
