Omron F3SJ-A0470N55 Safety Light Curtain
The Omron F3SJ-A0470N55 Safety Light Curtain provides leg and body protection across a 470 mm protective height for monitoring access to hazardous machine areas. Its sensing field uses 10 beam axes separated by a 50 mm beam gap, with an infrared LED operating at 870 nm as the optical light source. The model incorporates an NPN output configuration and a 5 mm lens diameter as part of its sensing arrangement. Operating from 24 VDC, it uses an M12 8-pin connector for electrical connection with compatible machine safety equipment. The F3SJ-A0470N55 identifies this configuration within the F3SJ Series and is positioned among body protection machine safety light curtains offered within Omron safety automation products.

The Omron F3SJ-A0470N55 is a F3SJ Safety Light Curtain commonly used in guarding, access detection, and protected-zone monitoring around automated machinery, conveyors, assembly modules, and packaging lines. It is often evaluated together with related models such as Omron F3SJ-A0695N14 (Finger protection, 9 mm beam gap, 76 axis beams, 695 mm protective height, NPN output, M12 Connector 8-pin) when engineers compare optical resolution, protective height, and wiring compatibility for specific machine layouts. Considering application type, beam gap, number of beams, protective height, output configuration, and connection method helps ensure proper selection for finger, hand, or body protection categories.
