The 15mm beam pitch and 18 beams create a 275mm protective height — sized for small assembly stations, pick-and-place cells, or conveyor infeed zones where a compact curtain covers the opening without overshooting the guarded area. Operating range spans 0.2m to 9.0m, so it fits both tight machine apertures and wider access points up to 9 meters between emitter and receiver. The 20mm detection capability (minimum object the curtain reliably sees) sets the minimum safe distance from the hazard per ISO 13855 — tighter detection lets you mount the curtain closer to the pinch point, saving floor space. The 275mm protective height defines the vertical zone covered; stack multiple curtains if your opening is taller. Blanking and muting functions are built in, so you can program fixed obstructions (a part fixture) or bypass the curtain during a non-hazardous material pass without an external safety controller. Runs on 24VDC, which is standard for safety circuits in modern panels — no separate power supply needed if your safety relay or PLC already provides 24V. ## Integration notes Mount the emitter and receiver on rigid brackets, aligned within the beam pitch tolerance. IP65 means no additional enclosure needed for washdown zones — just gland the cable entry. The 0.2m minimum range means you cannot use it for presence sensing inside a machine frame shorter than 200mm; plan your mounting distance accordingly.","metaTitle":"Omron F3SJ-A0275P20 Safety Light Curtain, 20mm Detection, 27","metaDescription":"Omron F3SJ-A0275P20 safety light curtain with 20mm detection capability, 275mm protective height, 15mm beam pitch, IP65.
