The Omron F3SG-4RA0190-30 Safety Light Curtain provides 30 mm hand and arm detection across a 190 mm protective height for safeguarding compact machine access areas. Its protective sensing field consists of 8 infrared beams arranged with a 20 mm beam gap to monitor intrusion through the guarded opening. The light curtain operates from a 24 VDC power supply and provides PNP/NPN safety outputs for integration with compatible machine safety systems. Its compact protective height supports localized hazardous access areas where hand and arm intrusion needs to be detected across a limited vertical zone. The F3SG-4RA0190-30 belongs to the F3SG-R Series and forms part of the 30 mm hand and arm light curtain range available within Omron machine safety products.
The Omron F3SG-4RA0190-30 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-4RA0990-30 (Hand and arm protection, 20 mm beam gap, 48 beams, 990 mm protective height), Omron F3SG-4RA0670-30 (Hand and arm protection, 20 mm beam gap, 32 beams, 670 mm protective height), and Omron F3SG-4RA0590-30 (Hand and arm protection, 20 mm beam gap, 28 beams, 590 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-4RA0190-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
