The Omron F3SG-4RA0640-14 Safety Light Curtain provides 14 mm finger detection across a 640 mm protective height for industrial machine areas requiring fine intrusion monitoring. Its protective field consists of 63 infrared beams positioned with a 10 mm beam gap, creating closely spaced sensing coverage across 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 640 mm protective height combines extended vertical coverage with fine finger-level detection around hazardous access areas. The F3SG-4RA0640-14 belongs to the F3SG-R Series and is categorized among 14 mm finger protection light curtains offered within Omron machine safety solutions.
The Omron F3SG-4RA0640-14 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-4RA0590-30 (Hand and arm protection, 20 mm beam gap, 28 beams, 590 mm protective height), Omron F3SG-4RA0990-30 (Hand and arm protection, 20 mm beam gap, 48 beams, 990 mm protective height), and Omron F3SG-4RA0160-14 (Finger protection, 10 mm beam gap, 15 beams, 160 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-4RA0640-14 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
