The Omron F3SG-4RA0990-30 Safety Light Curtain is designed for 30 mm hand and arm detection across a 990 mm protective height in industrial machine safeguarding systems. A protective field of 48 infrared beams with a 20 mm beam gap monitors personnel access through the guarded machine opening. Operating from 24 VDC, the light curtain provides PNP/NPN safety outputs for connection with compatible safety control architectures. Its protective field approaches one metre in height, providing substantial vertical coverage while retaining the specified hand and arm detection capability. The F3SG-4RA0990-30 belongs to the F3SG-R Series and sits within the hand and arm machine safety light curtain range associated with Omron safety automation products.
The Omron F3SG-4RA0990-30 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-4RA0480-14 (Finger protection, 10 mm beam gap, 47 beams, 480 mm protective height), Omron F3SG-4RA0350-30 (Hand and arm protection, 20 mm beam gap, 16 beams, 350 mm protective height), and Omron F3SG-4SRB0720-25 (Hand protection, 20 mm beam gap, 36 beams, 720 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-4RA0990-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
