The Omron F3SJ-A1260P25-TS is a type-4 safety light curtain from the F3SJ-A series, rated for hand protection with a 25 mm detection capability. That 25 mm figure means it catches a hand or finger reaching into the hazard zone — not just a full arm — so it meets the finger-protection class per IEC 61496 for point-of-operation guarding on presses, assembly stations, and packaging machines. The protective height spans 1260 mm, delivered by 63 beams at a 20 mm pitch. The operating range stretches from 0.2 m out to 9.0 m, which covers most reach-in guarding distances on a production line without needing a secondary set of emitters.
Blanking and muting — what that buys you
This unit carries blanking and muting function onboard. Blanking lets you disable specific beams so a fixed fixture or workpiece can pass through the curtain without tripping the safety output — useful on a conveyor where a product carrier breaks the beam intentionally. Muting temporarily suspends the safety function during a non-hazardous part of the cycle, like when a pallet enters a robot cell under slow speed. Both features are configurable, not hardwired, so you can adjust them per application without swapping optics.
Integration notes
Mounting this on a machine frame or stand: the 1260 mm protective height and 63-beam array mean the emitter and receiver columns need alignment within the specified tolerance. The IP65 rating lets you hose it down, but the M12 connectors (standard on the F3SJ-A series) should be oriented downward or capped to avoid pooling. The blanking and muting logic is set via the controller, not dip switches on the bar, so plan for a teach pendant or software connection during commissioning.
