The Omron F3SG-4RA0320-14 Safety Light Curtain is configured for 14 mm finger detection across a 320 mm protective height in machine areas requiring fine intrusion monitoring. Its sensing field consists of 31 infrared beams arranged with a 10 mm beam gap, creating closely spaced optical coverage across the guarded opening. The unit operates from a 24 VDC supply and provides PNP/NPN safety outputs for integration with compatible machine safety architectures. Its fine detection capability combined with the compact sensing height supports localized access points where finger-level safeguarding is required. The F3SG-4RA0320-14 represents this configuration within the F3SG-R Series and belongs to the 14 mm finger protection light curtain range associated with Omron machine safeguarding products.
The Omron F3SG-4RA0320-14 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-4SRB0800-25 (Hand protection, 20 mm beam gap, 40 beams, 800 mm protective height), Omron F3SG-4RA1550-30 (Hand and arm protection, 20 mm beam gap, 76 beams, 1550 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-4RA0320-14 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
