Omron F3SJ-E0785N25 Safety Light Curtain
The Omron F3SJ-E0785N25 Safety Light Curtain creates a protective sensing field for 25 mm hand detection across a 785 mm protective height. Its optical arrangement consists of 38 infrared beams separated by a 20 mm beam gap, providing sensing coverage across the guarded access area. Powered from 24 VDC, the unit uses an infrared LED light source for detecting intrusion into the protective field. The 785 mm protective height supports hand-level monitoring across a medium-sized vertical machine opening. The F3SJ-E0785N25 represents this configuration within the F3SJ Series and forms part of the hand detection safety light curtain range associated with Omron industrial safety products.

The Omron F3SJ-E0785N25 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-A0245P14 (Finger protection, 9 mm beam gap, 26 beams, 245 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-E0785N25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
