Omron F3SJ-E0705N25 Safety Light Curtain
The Omron F3SJ-E0705N25 Safety Light Curtain provides 25 mm hand detection over a 705 mm protective height for industrial machine safeguarding applications. Its sensing field uses 34 infrared beams positioned with a 20 mm beam gap to monitor hand intrusion through the protected machine opening. The light curtain operates from a 24 VDC power source and uses an infrared LED light source to establish its optical protective field. Its 705 mm sensing height provides increased vertical coverage compared with shorter F3SJ-E configurations while maintaining 25 mm detection capability. The F3SJ-E0705N25 belongs to the F3SJ Series and is positioned among 25 mm machine safety light curtains offered through Omron machine safeguarding products.

The Omron F3SJ-E0705N25 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-A0875P20 (Hand protection, 15 mm beam gap, 58 beams, 875 mm protective height, M12 Connector 8-pin), Omron F3SJ-B0385N25 (Hand protection, 20 mm beam gap, 18 beams, 385 mm protective height), and Omron F3SJ-A0245P20 (Hand protection, 15 mm beam gap, 16 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-E0705N25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
