Omron F3SJ-A0420P55 Safety Light Curtain
Omron F3SJ-A0420P55 is a Safety Light Curtain configured for leg and body protection across a 420 mm protective height. Its sensing field uses 9 beam axes arranged with a 50 mm beam gap and an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and PNP transistor outputs provide the electrical connection with the safety system. Within the F3SJ Series, the F3SJ-A0420P55 provides wider-spaced body detection.

The Omron F3SJ-A0420P55 Safety Light Curtain provides leg and body protection across a 420 mm protective height. Its optical field contains 9 beam axes arranged with a 50 mm beam gap and uses an 870 nm infrared LED source. The sensing range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector provides the electrical interface, and two PNP transistor outputs support maximum load currents of 300 mA each. Output short-circuit and power-supply reverse-polarity protection are specified. The enclosure carries an IP65 rating.
For installation, the F3SJ-A0420P55 should be selected according to its 50 mm beam spacing, 420 mm protected height, PNP output format, M12 connection, and operating range. These characteristics define a leg and body protection field rather than the finer finger or hand protection provided by closer beam spacing. The supplied data does not identify a specific comparison model for this unit, so selection should be based directly on its application category, beam count, protective height, output type, connector, and sensing distance.
