The Omron F3SJ-A0620N55 Safety Light Curtain provides 55 mm leg and body detection across a 620 mm protective height for monitoring access to hazardous industrial machine areas. Its sensing field consists of 13 infrared beams positioned with a 50 mm beam gap, creating optical coverage across the guarded opening. The unit operates from a 24 VDC power supply and uses an M12 8-pin connector for electrical integration with the machine safety architecture. Compared with finer hand or finger detection models, this configuration is intended for detecting larger body or leg intrusion into the protected area. The F3SJ-A0620N55 belongs to the F3SJ Series and is positioned within the 55 mm body protection light curtain range from Omron machine safety products.
The Omron F3SJ-A0620N55 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-A2470P55 (Leg/body protection, 50 mm beam gap, 50 beams, 2470 mm protective height, M12 Connector 8-pin) and Omron F3SJ-A1020N55 (Leg/body protection, 50 mm beam gap, 21 beams, 1020 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-A0620N55 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
