The Omron F3SG-4RA0590-30 Safety Light Curtain provides 30 mm hand and arm detection across a 590 mm protective height for safeguarding hazardous machine access points. Its sensing field consists of 28 infrared beams separated by a 20 mm beam gap to establish optical coverage across the protected opening. Powered by 24 VDC, the unit provides PNP/NPN safety outputs for connection with compatible machine safety equipment. Its 590 mm protective height provides greater vertical sensing coverage than smaller F3SG-R configurations while maintaining the specified hand and arm detection capability. The F3SG-4RA0590-30 identifies this model within the F3SG-R Series and forms part of the hand and arm protection light curtain range available through Omron industrial safety products.
The Omron F3SG-4RA0590-30 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-4SRB0320-14 (Finger protection, 10 mm beam gap, 31 beams, 320 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-4RA0590-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
