The Omron F3SJ-A1170N55 Safety Light Curtain monitors hazardous machine access with 55 mm detection capability for leg and body protection. Its sensing arrangement includes 24 infrared beams separated by a 50 mm beam gap, producing a 1170 mm protective height across the guarded area. The unit operates from a 24 VDC power supply and uses an M12 8-pin connector for electrical integration with the machine safety system. Its 1170 mm protective height provides extended vertical coverage, while the 55 mm detection specification is intended for larger personnel intrusion rather than fine hand or finger access. The F3SJ-A1170N55 belongs to the F3SJ Series and is categorized among 55 mm body protection light curtains available through Omron machine safety equipment.
The Omron F3SJ-A1170N55 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-A0620P30 (Hand/arm protection, 25 mm beam gap, 25 beams, 620 mm protective height, M12 Connector 8-pin), Omron F3SJ-E0225N25 (Hand protection, 20 mm beam gap, 10 beams, 225 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-A1170N55 integrates cleanly with safety relays, controllers, and emergency circuits where a reliable Omron Safety Light Curtain is required.
