The Omron F3SJ-A1655P20 is a F3SJ 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 F3SJ-A0920P30 (Hand/arm protection, 25 mm beam gap, 37 beams, 920 mm protective height, M12 Connector 8-pin), Omron F3SJ-A0470P55 (Leg/body protection, 50 mm beam gap, 10 beams, 470 mm protective height, M12 Connector 8-pin), and Omron F3SJ-E0385N25 (Hand protection, 20 mm beam gap, 18 beams, 385 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 F3SJ-A1655P20 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
