The Omron F3SG-4RA0240-14 is a F3SG Safety Light Curtain commonly used in guarding, access detection, and protected-zone monitoring around automated machinery, conveyors, assembly modules, and packaging lines. It is often evaluated together with related models such as Omron F3SJ-B0185P25 (Hand protection, 20 mm beam gap, 8 axis beams, 185 mm protective height, PNP output, M12 Connector 8-pin), Omron F3SJ-B0625P25 (Hand protection, 20 mm beam gap, 30 axis beams, 625 mm protective height, PNP output, M12 Connector 8-pin), and Omron F3SJ-B0305N25 (Hand protection, 20 mm beam gap, 14 axis beams, 305 mm protective height, NPN output, M12 Connector 8-pin) when engineers compare optical resolution, protective height, and wiring compatibility for specific machine layouts. Considering application type, beam gap, number of beams, protective height, output configuration, and connection method helps ensure proper selection for finger, hand, or body protection categories.
