Omron F3SJ-A0420P55 Safety Light Curtain
The Omron F3SJ-A0420P55 Safety Light Curtain provides leg and body protection across a 420 mm protective height for industrial machine safeguarding applications. Its protective sensing field consists of 9 beam axes arranged with a 50 mm beam gap and uses an infrared LED light source operating at 870 nm. The model provides a PNP output configuration and uses a 5 mm lens diameter within its optical sensing arrangement. It operates from 24 VDC and connects through an M12 8-pin connector for electrical integration with compatible machine safety equipment. The F3SJ-A0420P55 represents this configuration within the F3SJ Series and forms part of the leg and body protection light curtain range connected with Omron industrial safety solutions.
