The Omron F3SG-4SRA0320-25 Safety Light Curtain provides 25 mm hand detection across a 320 mm protective height for monitoring access to hazardous machine areas. Its protective sensing field consists of 16 infrared beams arranged with a 20 mm beam gap, providing optical coverage across the guarded opening. Operating from a 24 VDC power supply, the light curtain provides PNP/NPN safety outputs for integration with compatible machine safety control systems. The combination of 25 mm detection capability and a compact 320 mm sensing height supports localized access points requiring hand-level protection. The F3SG-4SRA0320-25 belongs to the F3SG-SR Series and can be compared with other 25 mm hand protection light curtains offered through Omron industrial safety solutions.
The Omron F3SG-4SRA0320-25 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-4RA0350-30 (Hand and arm protection, 20 mm beam gap, 16 beams, 350 mm protective height), Omron F3SG-4SRB1200-25 (Hand protection, 20 mm beam gap, 60 beams, 1200 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-4SRA0320-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
