The Omron F3SJ-A0570P30 is a Type 4 safety light curtain from the F3SJ-A series, rated for hand and arm protection with a 30 mm detection capability. That 30 mm figure means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it's suitable for guarding access points where operators might reach into a machine cycle. The 570 mm protective height, built from 23 beams at a 25 mm pitch, defines the vertical zone it covers. For a typical machine loading station, that height covers a mid-torso reach zone; pair it with a second curtain if the opening is taller. Operating range spans 0.2 m to 9.0 m, so it works in both tight cell entries and across wider conveyor access points.
Deployment context
Mount this light curtain at the hazard zone boundary — typically on a machine frame or standoff brackets — with the emitter and receiver aligned across the opening. The blanking and muting functions let it ignore fixed obstructions (like a fixture arm) and automatically bypass during a workpiece pass-through, which is common on palletized assembly lines.
The bulk packaging means it ships as a single unit with the emitter and receiver pair.
