The Omron F3SG-4SRB1040-25 Safety Light Curtain creates a protective sensing field for 25 mm hand detection across a 1040 mm protective height. Its sensing arrangement uses 52 infrared beams positioned with a 20 mm beam gap to monitor personnel access through the protected machine opening. The unit operates from 24 VDC and provides PNP/NPN safety outputs for connection with compatible machine safety control systems. Its protective height exceeding one metre provides extended vertical coverage while the 25 mm detection capability supports hand-level safeguarding around hazardous machine areas. The F3SG-4SRB1040-25 represents this configuration within the F3SG-SR Series and can be compared with other industrial hand detection light curtains available through Omron safety automation products.
The Omron F3SG-4SRB1040-25 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-4RA1950-30 (Hand and arm protection, 20 mm beam gap, 96 beams, 1950 mm protective height), Omron F3SG-4SRB0800-25 (Hand protection, 20 mm beam gap, 40 beams, 800 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-4SRB1040-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
