The Omron F3SG-4RA0270-30 Safety Light Curtain combines 30 mm hand and arm detection with a 270 mm protective height for industrial machine safeguarding applications. Its sensing field uses 12 infrared beams positioned with a 20 mm beam gap to monitor access through the protected machine opening. Operating from a 24 VDC supply, the unit provides PNP/NPN safety outputs for connection with compatible safety control equipment. The relationship between its detection capability, beam arrangement, and compact protective height defines the vertical access area monitored by this configuration. The F3SG-4RA0270-30 identifies this model within the F3SG-R Series and can be compared with other compact hand and arm protection light curtains available through Omron industrial safety solutions.
The Omron F3SG-4RA0270-30 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-4RA0640-14 (Finger protection, 10 mm beam gap, 63 beams, 640 mm protective height), Omron F3SG-4SRB1600-25 (Hand protection, 20 mm beam gap, 80 beams, 1600 mm protective height), and Omron F3SG-4RA0350-30 (Hand and arm protection, 20 mm beam gap, 16 beams, 350 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-4RA0270-30 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required to maintain operator safety.
