Omron F3SJ-A1805N20 Safety Light Curtain
The Omron F3SJ-A1805N20 Safety Light Curtain combines hand protection with an 1805 mm protective height for industrial machines requiring extended vertical safeguarding. Its sensing field uses 120 beam axes separated by a 15 mm beam gap to monitor intrusion through the guarded machine opening. The optical system uses an infrared LED operating at 870 nm and a 5 mm lens, while the NPN output provides the specified electrical configuration for compatible safety equipment. Operating from 24 VDC, the unit connects through an M12 8-pin connector for machine integration. The F3SJ-A1805N20 belongs to the F3SJ Series and is positioned within the extended-height hand protection light curtain range available as part of Omron machine safety solutions.

The Omron F3SJ-A1805N20 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-A0803P14 (Finger protection, 9 mm beam gap, 88 axis beams, 803 mm protective height, PNP output, M12 Connector 8-pin), Omron F3SJ-A1195N30 (Hand/arm protection, 25 mm beam gap, 48 axis beams, 1195 mm protective height, NPN output, M12 Connector 8-pin), and Omron F3SJ-A1055N14 (Finger protection, 9 mm beam gap, 116 axis beams, 1055 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.
