The Omron F3SG-4SRB0320-25 Safety Light Curtain combines 25 mm hand detection with a 320 mm protective height for monitoring smaller industrial machine access areas. Its protective sensing field consists of 16 infrared beams arranged with a 20 mm beam gap to monitor intrusion through the guarded opening. The unit operates from a 24 VDC supply and provides PNP/NPN safety outputs for integration with compatible machine safety architectures. Its compact protective height provides localized vertical coverage, while the 25 mm detection capability supports hand-level safeguarding around hazardous machine zones. The F3SG-4SRB0320-25 belongs to the F3SG-SR Series and can be compared with other compact hand protection light curtains available through Omron machine safeguarding products.
The Omron F3SG-4SRB0320-25 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-4SRB0480-25 (Hand protection, 20 mm beam gap, 24 beams, 480 mm protective height), and Omron F3SG-4RA0400-14 (Finger protection, 10 mm beam gap, 39 beams, 400 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-4SRB0320-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety and comply.
