The 420 mm protective height and 9 beams at 50 mm pitch define the guarded area; the operating range spans 0.2 m to 9.0 m, so it handles both close-in and across-the-aisle guarding. ## Deployment context Rated IP65 — dust-tight and protected against water jets — so it holds up on washdown lines, outdoor conveyor transfers, or anywhere hose-down cleaning is routine. The 24 VDC supply is standard for safety circuits; it mates directly to a safety relay or safety PLC input without a separate power supply in most panels. Blanking and muting functions are built in, which lets the curtain ignore fixed obstructions (blanking) or temporarily suspend guarding during a material pass-through (muting) — useful on palletizing cells or automated guided vehicle interfaces.","metaTitle":"Omron F3SJ-A0420P55 Safety Light Curtain, 55mm Detection, 42","metaDescription":"Omron F3SJ-A0420P55 safety light curtain, 55mm detection capability for leg/body protection, 420mm protective height, 50mm beam pitch, 9 beams, 0.2-9.0m range, IP65, 24VDC.
