The 1920 mm protective height and 39 beams at a 50 mm pitch cover a full standing-height opening, so a single unit guards a doorway or conveyor access point up to that height. Operating range spans 0.2 m to 7.0 m, which suits most machine-guarding distances from the hazard point back to the mounting standoff. The 24 VDC supply is standard for safety circuits tied to a safety PLC or relay module. IP65 rating means the emitter and receiver housings tolerate washdown from hoses and dust ingress — fit for food-processing lines, packaging floors, or outdoor-adjacent positions where water spray is routine. ## Blanking and Muting — When the Curtain Needs to Ignore a Fixed Obstruction Built-in blanking and muting functions let the F3SJ-A1920P55 ignore a stationary object (like a conveyor frame or pallet) passing through the field, or temporarily suspend the safety output during a defined material-handling cycle. This avoids nuisance trips that stop production when a workpiece or fixture breaks the beam. The blanking zone is programmable via the controller — no separate bypass module needed. ## Integration Checklist — What to Verify Before Mounting Mount the emitter and receiver on opposite sides of the guarded opening, aligned within the specified beam pitch tolerance. The 50 mm beam pitch means a 55 mm detection object is caught between two adjacent beams — ensure the mounting height covers the full 1920 mm protective height with no gap at the bottom or top.","metaTitle":"Omron F3SJ-A1920P55 Safety Light Curtain, 55 mm Detection","metaDescription":"Omron F3SJ-A1920P55 safety light curtain, 55 mm detection capability, 1920 mm protective height, 39 beams at 50 mm pitch, IP65, 24 VDC.
