The Omron F3SJ-B0385N25 Safety Light Curtain combines 25 mm hand detection with a 385 mm protective height for monitoring access to industrial machine areas. Its sensing field uses 18 infrared beams separated by a 20 mm beam gap, establishing optical protection across the guarded opening. Powered from a 24 VDC supply, this model provides hand-level intrusion monitoring across a relatively compact vertical access zone. The relationship between its 25 mm detection capability, 18-beam arrangement, and 385 mm sensing height defines the protective field for this configuration. The F3SJ-B0385N25 identifies this model within the F3SJ Series and forms part of the 25 mm hand protection safety light curtain range available within Omron machine safety products.

The Omron F3SJ-B0385N25 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-A0635P20 (Hand protection, 15 mm beam gap, 42 beams, 635 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-B0385N25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light.
