The Omron F3SG-4RA1230-30 Safety Light Curtain provides 30 mm hand and arm detection across a 1230 mm protective height for industrial machine safeguarding. Its protective sensing field consists of 60 infrared beams arranged with a 20 mm beam gap to monitor personnel access through the guarded machine opening. Operating from a 24 VDC power supply, the light curtain provides PNP/NPN safety outputs for integration with compatible safety control architectures. Its 1230 mm protective height provides extended vertical coverage, while the 30 mm detection capability supports hand and arm protection around hazardous access areas. The F3SG-4RA1230-30 belongs to the F3SG-R Series and can be compared with other 30 mm hand and arm light curtains available within Omron machine safety products.
The Omron F3SG-4RA1230-30 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-4RA0190-30 (Hand and arm protection, 20 mm beam gap, 8 beams, 190 mm protective height), Omron F3SG-4SRA0320-25 (Hand protection, 20 mm beam gap, 16 beams, 320 mm protective height), and Omron F3SG-4RA0910-30 (Hand and arm protection, 20 mm beam gap, 44 beams, 910 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-4RA1230-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
