With 45 beams at 50 mm pitch, it creates a 2220 mm protective curtain, covering the full height of a typical access area around a press, robot cell, or conveyor infeed. The operating range spans 0.2 m to 7.0 m, so it fits both short-reach guarding near the hazard and longer spans across a wider access point. Powered by 24 VDC, it integrates into standard safety circuits without a separate power supply. Built-in blanking and muting functions give flexibility to handle fixed obstructions (like a machine frame passing through the field) or temporary interruptions during material feed cycles, without tripping the safety output. These are configurable features that reduce nuisance downtime on automated lines. Because this is a safety device, the documentation package — including the declaration of conformity, wiring diagram, and configuration manual — is essential for the machine's safety file. The F3SJ-A series is a mature, widely deployed platform, so compliance records (CE, UL, etc.) are well established and available through the Omron support network. ## Installation Fit Mounting columns and brackets for the F3SJ-A series are standard Omron accessories; the 2220 mm column height requires a rigid mount to maintain alignment over the full 7.0 m range. The emitter and receiver are wired separately back to a safety controller or relay — the 24 VDC supply is common, but the outputs (OSSD pairs) must go to a safety-rated input card or safety PLC. Blanking and muting require configuration via the Omron setup tool or DIP switches on the control box, depending on the variant. The IP65 enclosure means the connector end caps and cable glands are sealed; no additional panel-side protection is needed for washdown zones.","metaTitle":"Omron F3SJ-A2220P55 Safety Light Curtain, 55mm Detection, 22","metaDescription":"Omron F3SJ-A2220P55 safety light curtain. 55mm detection capability, 2220mm protective height, 7.0m range, IP65, 24VDC.

It will reliably detect a leg or torso entering the field, but it will not detect a hand or finger — for hand protection you would need a curtain with a smaller beam pitch, typically 14 mm or 30 mm."},{"question":"What is the protective height and how many beams does it use?","answer":"The protective height is 2220 mm, achieved with 45 beams spaced at 50 mm pitch. This covers the full height of a typical standing-person access area."},{"question":"Can this light curtain be used in washdown environments?","answer":"Yes, the IP65 rating makes it dust-tight and protected against water jets, so it is suitable for washdown in food processing or wet machining areas. It is not rated for continuous immersion."},{"question":"What features does the F3SJ-A2220P55 support?","answer":"It supports blanking (to ignore fixed obstructions in the field) and muting (to temporarily bypass the curtain during material feed cycles).
