Its 62 beams create a 935 mm protective height, covering access openings on automated machinery, conveyor infeed/outfeed, and palletizing cells where an operator could reach into a hazard zone. The 0.2 m to 9.0 m operating range gives flexibility to guard wide or narrow gaps without repositioning the emitter and receiver pair. A 20 mm detection capability and 15 mm beam pitch classify this as finger-protection class per IEC 61496-1/2 — it catches fingers reaching past the light plane, not just a hand or torso. The 935 mm protective height means it guards a vertical zone just under a meter tall; for taller openings you stack multiple units or move to a longer model in the same series. The 0.2 m minimum range is short enough to fit tight machine frames, while the 9.0 m maximum covers most single-aisle guarding layouts without needing a second pair. IP65 rating means the emitter and receiver housings are dust-tight and withstand hose-directed water — suitable for washdown areas in food processing or general manufacturing where coolant mist and wash cycles are routine. The 24 VDC supply is standard for safety circuits tied to a safety PLC or safety relay; no separate power supply module is needed if the control cabinet already provides 24 VDC. ## Built-in flexibility for production lines Blanking and muting functions are included onboard. Blanking lets the light curtain ignore fixed obstructions (e.g., a conveyor frame passing through the detection zone) without disabling the entire safety function. Muting temporarily suspends the safety output during a defined material pass cycle — common on palletizing cells where a pallet load must break the light plane without triggering a stop. Both functions are configurable without an external controller, reducing wiring and panel space.","metaTitle":"Omron F3SJ-A0935P20 Light Curtain, Finger/Hand 20mm, 935mm","metaDescription":"Omron F3SJ-A0935P20 safety light curtain, 20mm detection capability, 935mm protective height, 0.2-9.0m range, 24VDC, IP65.
