The Omron F3SJ-A1920N55 Safety Light Curtain monitors personnel access with 55 mm leg and body detection across a 1920 mm protective height. Its protective sensing field consists of 39 infrared beams positioned with a 50 mm beam gap, providing substantial vertical coverage across the guarded machine opening. The light curtain operates from a 24 VDC supply and uses an M12 8-pin connector for electrical connection with the machine safety circuit. Its combination of larger-object detection and a protective field approaching two metres supports body-level monitoring across tall hazardous access zones. The F3SJ-A1920N55 represents this configuration within the F3SJ Series and can be evaluated alongside other leg and body protection safety light curtains available through Omron machine safety equipment.
The Omron F3SJ-A1920N55 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-E0945P25 (Hand protection, 20 mm beam gap, 46 beams, 945 mm protective height), Omron F3SJ-A0395P30 (Hand/arm protection, 25 mm beam gap, 16 beams, 395 mm protective height, M12 Connector 8-pin), and Omron F3SJ-A2405N20 (Hand protection, 15 mm beam gap, 160 beams, 2405 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-A1920N55 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
