The Omron F3SJ-A1120P30 is a type-4 safety light curtain from the F3SJ-A series, rated for hand and arm protection with a 30mm detection capability. That 30mm figure means it catches fingers and hands reaching into the hazard zone — finger-protection class per IEC 61496-1. The 1120mm protective height and 45 beams at 25mm pitch cover a wide vertical access area typical of machine loading stations or robot cells.
Range and environment
Operating range spans 0.2m to 9.0m, so it works for both tight reach-in guarding and wider perimeter setups. IP65 rating means the housing and optics withstand washdown and dust — suitable for food-and-bev lines or machining areas where coolant mist is present.
Integration features
Built-in blanking and muting functions let you configure fixed obstructions (like a conveyor frame passing through the curtain) and automatic bypass for material flow. That saves adding external logic modules for common machine-guarding layouts. Runs on 24VDC supply — standard for safety circuits.
