The Omron F3SJ-E0545N25 Safety Light Curtain combines 25 mm hand detection with a 545 mm protective height for monitoring personnel access around hazardous machinery. Its protective field consists of 26 infrared beams arranged with a 20 mm beam gap, creating optical sensing coverage across the guarded machine opening. Powered from 24 VDC, the unit uses an infrared LED light source to detect interruption of the protective field. The 545 mm protective height provides increased vertical coverage while maintaining the 25 mm detection capability intended for hand protection. The F3SJ-E0545N25 represents this configuration within the F3SJ Series and belongs to the 25 mm hand protection safety light curtain range available as part of Omron industrial safety products.

The Omron F3SJ-E0545N25 is a F3SJ Safety Light Curtain designed for use in machine guarding, access protection, and point-of-operation safety around conveyors, presses, and automated lines. It is usually evaluated together with related models such as Omron F3SJ-A1620P30 (Hand/arm protection, 25 mm beam gap, 65 beams, 1620 mm protective height, M12 Connector 8-pin), Omron F3SJ-A1020N55 (Leg/body protection, 50 mm beam gap, 21 beams, 1020 mm protective height, M12 Connector 8-pin) when engineers are matching safety light curtains to application risk levels and space constraints. Reviewing application type, beam gap, number of beams, protective height, and connection method makes it easier to select the right curtain for finger protection, hand detection, or body protection zones along the machine. The F3SJ-E0545N25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
