The Omron F3SG-4SRB0400-25 Safety Light Curtain provides 25 mm hand detection across a 400 mm protective height for safeguarding industrial machine access points. Its optical field uses 20 infrared beams positioned with a 20 mm beam gap to monitor hand intrusion across the guarded opening. Operating from a 24 VDC power supply, the light curtain provides PNP/NPN safety outputs for electrical integration with compatible safety control systems. The 400 mm protective height provides compact vertical coverage while retaining the hand-detection characteristics of this F3SG-SR configuration. The F3SG-4SRB0400-25 represents this model within the F3SG-SR Series and forms part of the 25 mm hand protection safety light curtain range available within Omron industrial safety products.
The Omron F3SG-4SRB0400-25 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-4SRB1600-25 (Hand protection, 20 mm beam gap, 80 beams, 1600 mm protective height), Omron F3SG-4RA0480-14 (Finger protection, 10 mm beam gap, 47 beams, 480 mm protective height), and Omron F3SG-4RA0750-30 (Hand and arm protection, 20 mm beam gap, 36 beams, 750 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-4SRB0400-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
