The Omron F3SJ-A2405N20 Safety Light Curtain provides 20 mm hand detection across a 2405 mm protective height for safeguarding tall industrial machine access areas. Its sensing field consists of 160 infrared beams arranged with a 15 mm beam gap, creating extensive optical coverage across the guarded opening. The light curtain operates from a 24 VDC power supply and uses an M12 8-pin connector for integration with the associated machine safety circuit. Its fine hand detection combined with more than two metres of vertical sensing coverage supports large access points where intrusion needs to be monitored throughout a tall protected zone. The F3SJ-A2405N20 belongs to the F3SJ Series and forms part of the 20 mm hand protection light curtain range available within Omron machine safety products.
The Omron F3SJ-A2405N20 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-E0305N25 (Hand protection, 20 mm beam gap, 14 beams, 305 mm protective height) and Omron F3SJ-B0225P25 (Hand protection, 20 mm beam gap, 10 beams, 225 mm protective height) 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-A2405N20 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator.
