Omron F3SJ-A0545N20 Safety Light Curtain
The Omron F3SJ-A0545N20 Safety Light Curtain creates a protective sensing field for 20 mm hand detection across a 545 mm protective height. Its optical arrangement uses 36 infrared beams with a 15 mm beam gap to monitor intrusion through the protected machine opening. The light curtain operates from a 24 VDC power supply and connects through an M12 8-pin connector for integration with compatible machine safety equipment. Its 545 mm sensing height provides greater vertical coverage than compact models while retaining the finer hand-detection capability of this configuration. The F3SJ-A0545N20 belongs to the F3SJ Series and sits within the 20 mm hand detection safety light curtain range offered through Omron machine safeguarding products.

The Omron F3SJ-A0545N20 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-A0245P30 (Hand/arm protection, 25 mm beam gap, 10 beams, 245 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-A0545N20 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
