The Omron F3SJ-A1955P20 Safety Light Curtain is designed for hand protection across a 1955 mm protective height, providing extensive sensing coverage for tall industrial machine access areas. Its protective field consists of 130 beam axes arranged with a 15 mm beam gap to monitor intrusion through the guarded opening. An infrared LED operating at 870 nm together with a 5 mm lens forms the optical sensing arrangement, while the PNP output supports connection with compatible machine safety equipment. Powered from 24 VDC, the light curtain uses an M12 8-pin connector for electrical integration. The F3SJ-A1955P20 belongs to the F3SJ Series and sits within the industrial hand protection light curtain range associated with Omron machine safety equipment.
The Omron F3SJ-A1955P20 is a F3SJ 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-A0263P14 (Finger protection, 9 mm beam gap, 28 axis beams, 263 mm protective height, PNP output, M12 Connector 8-pin), Omron F3SJ-A0870N55 (Leg/body protection, 50 mm beam gap, 18 axis beams, 870 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.
