Omron F3SJ-A0570N55 Safety Light Curtain
The Omron F3SJ-A0570N55 Safety Light Curtain is designed for leg and body protection across a 570 mm protective height in industrial machine safety applications. Its protective field consists of 12 beam axes with a 50 mm beam gap and uses an infrared LED light source operating at 870 nm. An NPN output configuration provides the specified electrical output, while the 5 mm lens diameter forms part of the optical sensing design. The unit operates from a 24 VDC supply and uses an M12 8-pin connector for integration with compatible safety equipment. The F3SJ-A0570N55 belongs to the F3SJ Series and can be evaluated alongside other industrial body protection light curtains available within Omron machine safety products.

The Omron F3SJ-A0570N55 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-A1025N20 (Hand protection, 15 mm beam gap, 68 axis beams, 1025 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.
