Omron F3SJ-A2220N55 Safety Light Curtain
Omron F3SJ-A2220N55 is a Safety Light Curtain configured for 55 mm leg and body protection across a 2220 mm protective height. Its protective field contains 45 infrared beams positioned with a 50 mm beam gap to detect opaque objects entering a large guarded machine opening. The operating range extends from 0.2 to 7 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide the electrical interface. Within the F3SJ Series, the F3SJ-A2220N55 provides substantial body-level vertical coverage.

The Omron F3SJ-A2220N55 Safety Light Curtain provides 55 mm leg and body detection across a 2220 mm protective height. Its sensing field contains 45 infrared beams arranged with a 50 mm beam gap to detect opaque objects entering a tall guarded machine opening. The operating range extends from 0.2 to 7 m, while the unit operates from a 24 VDC ±20% supply. An M12 8-pin connector provides electrical connection. Two NPN transistor outputs support a maximum load current of 300 mA each. Output short-circuit and power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 rating.
For model selection, the F3SJ-A2220N55 should be evaluated by its 55 mm detection capability, 2220 mm protective height, 50 mm beam spacing, NPN output format, and available sensing distance. These specifications define an extensive leg and body protection field and its electrical interface. The supplied source does not list a specific related model for direct comparison, so selection should remain grounded in the stated detection category, beam count, protected height, output type, M12 connection, and operating range without adding an unsupported comparison model.
