The Omron F3SJ-A1655P20 Safety Light Curtain provides 20 mm hand detection across a 1655 mm protective height for monitoring tall machine access points. A dense protective field of 110 infrared beams arranged with a 15 mm beam gap detects hand intrusion across the guarded opening. The light curtain operates from a 24 VDC power supply and connects through an M12 8-pin connector for integration with compatible machine safety equipment. Its 20 mm detection capability provides finer hand-level sensing than configurations intended for hand and arm or body protection, while the 1655 mm sensing height provides extensive vertical coverage. The F3SJ-A1655P20 identifies this configuration within the F3SJ Series and belongs to the extended-height hand protection light curtain range offered through Omron safety automation products.
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) 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.
