The Omron F3SG-4RA1550-30 Safety Light Curtain provides 30 mm hand and arm detection across a 1550 mm protective height for safeguarding tall industrial machine openings. Its protective sensing field consists of 76 infrared beams arranged with a 20 mm beam gap, providing extended optical coverage across the guarded access area. Operating from 24 VDC, the light curtain provides PNP/NPN safety outputs for connection with compatible machine safety equipment. The 1550 mm protective height makes this configuration relevant where hand and arm protection must extend across a substantial vertical access zone. The F3SG-4RA1550-30 identifies this model within the F3SG-R Series and forms part of the extended-height machine safety light curtain range associated with Omron industrial safety equipment.
The Omron F3SG-4RA1550-30 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-4RA0160-14 (Finger protection, 10 mm beam gap, 15 beams, 160 mm protective height), Omron F3SG-4RA0830-30 (Hand and arm protection, 20 mm beam gap, 40 beams, 830 mm protective height), and Omron F3SG-4RA0510-30 (Hand and arm protection, 20 mm beam gap, 24 beams, 510 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-4RA1550-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain.
