Omron F3SJ-A0870N55 Safety Light Curtain
Omron F3SJ-A0870N55 is a Safety Light Curtain designed for leg and body protection across an 870 mm protective height. Its sensing field contains 18 beam axes arranged with a 50 mm beam gap and uses an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, while the unit operates from 24 VDC. An M12 8-pin connector and NPN transistor outputs provide the electrical interface with compatible safety equipment. Within the F3SJ Series, the F3SJ-A0870N55 provides wider-spaced body protection across an extended area.

The Omron F3SJ-A0870N55 Safety Light Curtain provides leg and body protection across an 870 mm protective height. Its sensing field consists of 18 beam axes arranged with a 50 mm beam gap and uses 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 provides the electrical interface. Two NPN transistor outputs support maximum load currents of 300 mA each. Output short-circuit and reverse-polarity protection are specified, while the enclosure carries an IP65 protection rating.
When choosing the F3SJ-A0870N55, the 50 mm beam spacing, 870 mm protective height, NPN output configuration, M12 connector, and operating distance are the main parameters to compare. These specifications define a leg and body protection field rather than a fine hand or finger detection zone. The supplied source does not identify a specific comparison model for this unit, so model selection should rely on the stated protection category, number of beam axes, protected height, output format, connection method, and sensing range without adding an unsupported alternative.
