What this light curtain covers
The Omron F3SJ-A1500P25-TS is a 1500mm protective-height safety light curtain from the F3SJ-A series, designed for hand protection with a 25mm detection capability. It uses 75 beams spaced at 20mm pitch to create a sensing field that catches fingers and hands reaching into a hazard zone — the 25mm detection capability is the finger-protection class per IEC 61496-1, meaning it reliably detects objects that size or larger.
Where it goes and what it handles
Rated IP65 (dust-tight and water-resistant), this curtain stands up to washdown environments in food-and-beverage or packaging lines — the emitter and receiver housings seal against hose-directed water. Operating range spans 0.2m to 9.0m, so it fits guarding applications from compact assembly stations up to wider conveyor access points. Supply is 24VDC, standard for safety circuits.
Built-in flexibility
Blanking and muting functions are built in — blanking lets you disable selected beams to allow fixed objects (like a fixture or part) to pass through the field without tripping the safety output, while muting temporarily overrides the curtain during a controlled material pass (e.g., a pallet entering a machine zone). These are programmed via the controller, not hard-wired, which simplifies panel wiring.
