The Omron F3SG-4SRB0720-25 Safety Light Curtain is designed for 25 mm hand detection across a 720 mm protective height in industrial machine safeguarding systems. A protective sensing field of 36 infrared beams arranged with a 20 mm beam gap monitors hand intrusion through the guarded access area. The unit operates from a 24 VDC power source and provides PNP/NPN safety outputs for integration with compatible machine safety control equipment. Its 720 mm protective height provides greater vertical sensing coverage than compact configurations while maintaining hand-level detection across the protected opening. The F3SG-4SRB0720-25 belongs to the F3SG-SR Series and is positioned among 25 mm hand protection light curtains available through Omron industrial safeguarding products.
The Omron F3SG-4SRB0720-25 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-4RA0990-30 (Hand and arm protection, 20 mm beam gap, 48 beams, 990 mm protective height), Omron F3SG-4SRB0960-25 (Hand protection, 20 mm beam gap, 48 beams, 960 mm protective height), and Omron F3SG-4SRB0320-14 (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-4SRB0720-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
