The Omron F3SJ-A0950P20-01TS is a type-4 safety light curtain from the F3SJ-A series, rated for finger and hand detection with a 20 mm detection capability. That 20 mm figure means the curtain catches a finger reaching into the hazard zone — finger-protection class per IEC 61496 — so it is suitable for guarding access to presses, assembly stations, or robotic cells where an operator's hands could enter the danger area. The 63 beams at a 15 mm pitch cover a 950 mm protective height, giving a detection plane that spans typical small-parts machine openings. Built-in blanking and muting functions allow the curtain to ignore fixed obstructions (like a fixture jig) and automatically bypass during a workpiece pass-through, respectively. These are configurable features that reduce false trips on automated lines without compromising safety integrity.
Runs on 24 VDC supply, so it integrates directly into standard control-panel power without a separate transformer. The IP65 rating means the emitter and receiver housings are dust-tight and protected against water jets — suitable for washdown environments in food processing or automotive machining lines where coolant mist and hose-down cleaning are routine. Operating range spans 0.2 m to 9.0 m, covering both close-proximity guarding and longer reach across a conveyor or machine throat.
