The Omron F3SG-4RA0720-14 Safety Light Curtain is configured for 14 mm finger detection across a 720 mm protective height in industrial machine safeguarding applications. Its sensing field uses 71 infrared beams positioned with a 10 mm beam gap, creating closely spaced optical coverage for monitoring finger-level intrusion through the protected opening. Operating from 24 VDC, the unit provides PNP/NPN safety outputs for connection with compatible safety control equipment. The combination of fine 14 mm detection and 720 mm vertical coverage supports hazardous access areas requiring finger protection across an extended sensing field. The F3SG-4RA0720-14 identifies this configuration within the F3SG-R Series and belongs to the 14 mm finger protection light curtain range associated with Omron industrial safety solutions.
The Omron F3SG-4RA0720-14 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-4SRB1040-25 (Hand protection, 20 mm beam gap, 52 beams, 1040 mm protective height), and Omron F3SG-4SRA1200-25 (Hand protection, 20 mm beam gap, 60 beams, 1200 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-4RA0720-14 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety and comply.
