Omron F3SG-4SRB0640-25 Safety Light Curtain
The Omron F3SG-4SRB0640-25 Safety Light Curtain creates a protective sensing field for 25 mm hand detection across a 640 mm protective height. Its optical arrangement consists of 32 infrared beams positioned with a 20 mm beam gap to monitor personnel access through the guarded machine area. Powered from 24 VDC, the unit provides PNP/NPN safety outputs for connection with compatible machine safety control equipment. The 640 mm protective height extends hand-level monitoring across a larger vertical access zone while maintaining the specified detection capability. The F3SG-4SRB0640-25 belongs to the F3SG-SR Series and is positioned among 25 mm machine safety light curtains available as part of Omron industrial safety products.

The Omron F3SG-4SRB0640-25 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-4RA0720-14 (Finger protection, 10 mm beam gap, 71 beams, 720 mm protective height), Omron F3SG-4SRA0320-25 (Hand protection, 20 mm beam gap, 16 beams, 320 mm protective height), and Omron F3SG-4RA0830-30 (Hand and arm protection, 20 mm beam gap, 40 beams, 830 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-4SRB0640-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
