Omron F3SJ-A1020N55 Safety Light Curtain
The Omron F3SJ-A1020N55 Safety Light Curtain provides 55 mm leg and body detection over a 1020 mm protective height for industrial machine safeguarding. Its protective field consists of 21 infrared beams positioned with a 50 mm beam gap to monitor personnel entry through the guarded machine opening. The unit operates from a 24 VDC supply and uses an M12 8-pin connector for integration with the associated machine safety system. The 55 mm detection capability is intended for larger personnel intrusion, while the 1020 mm sensing height provides more than one metre of vertical coverage. The F3SJ-A1020N55 belongs to the F3SJ Series and is positioned among body detection safety light curtains available within Omron industrial safety solutions.

The Omron F3SJ-A1020N55 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-A2495P30 (Hand/arm protection, 25 mm beam gap, 100 beams, 2495 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-A1020N55 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
