The Omron F3SG-4RA0400-14 Safety Light Curtain provides 14 mm finger detection across a 400 mm protective height for safeguarding access to hazardous machine zones. Its sensing field uses 39 infrared beams arranged with a 10 mm beam gap to provide closely spaced optical coverage across the protected opening. Powered from 24 VDC, the light curtain provides PNP/NPN safety outputs for connection with compatible machine safety systems. The combination of fine detection, close beam spacing, and 400 mm protective height supports finger-level intrusion monitoring across a compact vertical access area. The F3SG-4RA0400-14 identifies this configuration within the F3SG-R Series and forms part of the finger protection safety light curtain range offered through Omron machine safety solutions.
The Omron F3SG-4RA0400-14 is a F3SG 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 F3SG-4RA1550-30 (Hand and arm protection, 20 mm beam gap, 76 beams, 1550 mm protective height), Omron F3SG-4RA0160-14 (Finger protection, 10 mm beam gap, 15 beams, 160 mm protective height), and Omron F3SG-4RA0320-14 (Finger protection, 10 mm beam gap, 31 beams, 320 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 F3SG-4RA0400-14 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
