The Omron F3SJ-A1320P55 is a Type 4 safety light curtain from the F3SJ-A series, designed for leg and body protection on access points like press brakes, assembly stations, and robotic cells. Its 55 mm detection capability means it catches a full leg or torso entering the hazard zone — not fingers or hands — so it is sized for perimeter guarding rather than point-of-operation. The 1320 mm protective height, formed by 27 beams at 50 mm pitch, covers a standard doorway or machine access opening. Operating range spans 0.2 m to 9.0 m, which suits most cell layouts without requiring a mirror tower.
Runs on 24 VDC, which is the standard safety-circuit supply in most panels — no special power rail needed. Built-in blanking and muting functions let the curtain ignore fixed obstructions (conveyor frames, part fixtures) and automatically bypass during a workpiece pass-through — both configurable without an external safety PLC.
