The Omron F3SG-4SRB1520-25 Safety Light Curtain combines 25 mm hand detection with a 1520 mm protective height for monitoring access around industrial machinery. Its protective sensing field consists of 76 infrared beams arranged with a 20 mm beam gap, providing extended optical coverage across the guarded machine opening. Operating from a 24 VDC supply, the light curtain provides PNP/NPN safety outputs for integration with compatible safety control equipment. The 1520 mm protective height supports taller access areas where hand intrusion needs to be detected across an extended vertical zone. The F3SG-4SRB1520-25 belongs to the F3SG-SR Series and forms part of the extended-height hand protection light curtain range available within Omron industrial safety products.
The Omron F3SG-4SRB1520-25 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-4RA0590-30 (Hand and arm protection, 20 mm beam gap, 28 beams, 590 mm protective height), Omron F3SG-4SRB0640-25 (Hand protection, 20 mm beam gap, 32 beams, 640 mm protective height), and Omron F3SG-4SRB0560-25 (Hand protection, 20 mm beam gap, 28 beams, 560 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-4SRB1520-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
