That 20 mm figure means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits guarding around assembly stations, pick-and-place cells, and small-part presses where hand access must be blocked without a physical barrier. The curtain projects 52 beams at a 15 mm pitch across a 785 mm protective height, covering a 0.2 m to 9.0 m operating range. The 52-beam count and 15 mm pitch are what deliver that 20 mm detection capability — no gaps larger than the rated object size. ## Deployment context and environment Suitable for food-and-bev lines, packaging floors, and other wet or dusty environments where a standard IP54 curtain would fog or fail. Supply is 24 VDC, standard for safety circuits. Operating temperature spans -10°C to 55°C, covering most factory-floor conditions without derating. ## Built-in logic for production flexibility Includes blanking and muting functions onboard. Blanking lets you disable selected beams for a fixed obstruction (e.g., a fixture or conveyor rail) without disabling the whole curtain. Muting temporarily suspends the safety output during a defined material pass — useful when a workpiece enters the guarded area on a conveyor and the cycle needs to continue without a trip.","metaTitle":"Omron F3SJ-A0785P20 Light Curtain, 20mm Detection, 785mm Hei","metaDescription":"Omron F3SJ-A0785P20 safety light curtain with 20mm finger/hand detection, 785mm protective height, 52 beams, 15mm pitch, IP65.
