Omron F3SG-4SRA1200-25 Safety Light Curtain
The Omron F3SG-4SRA1200-25 Safety Light Curtain provides 25 mm hand detection across a 1200 mm protective height for safeguarding access to hazardous machine areas. Its protective sensing field consists of 60 infrared beams arranged with a 20 mm beam gap to monitor hand intrusion through 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 1200 mm protective height provides extended vertical coverage while maintaining the specified hand-level detection capability. The F3SG-4SRA1200-25 belongs to the F3SG-SR Series and forms part of the 25 mm hand protection light curtain range available within Omron machine safety products.

The Omron F3SG-4SRA1200-25 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-4RA1070-30 (Hand and arm protection, 20 mm beam gap, 52 beams, 1070 mm protective height), Omron F3SG-4SRB0760-25-F (Hand protection, 20 mm beam gap, 38 beams, 760 mm protective height), and Omron F3SG-4RA1550-30 (Hand and arm protection, 20 mm beam gap, 76 beams, 1550 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-4SRA1200-25 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
