Omron F3SJ-A0470N55 Safety Light Curtain
Omron F3SJ-A0470N55 is a Safety Light Curtain configured for leg and body protection across a 470 mm protective height. Its optical field uses 10 beam axes arranged with a 50 mm beam gap and an 870 nm infrared LED light source. The sensing distance extends from 0.2 to 9 m, while electrical operation is based on a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide connection with the safety system. Within the F3SJ Series, the F3SJ-A0470N55 provides wider-spaced body detection with NPN outputs.

The Omron F3SJ-A0470N55 Safety Light Curtain provides leg and body protection across a 470 mm protective height. Its optical field contains 10 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 electrical operation is based on a 24 VDC supply. An M12 8-pin connector provides the interface with the safety circuit. 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 rating.
When evaluating the F3SJ-A0470N55, its 50 mm beam spacing, 470 mm protective height, NPN output format, connector type, and sensing range are the main parameters to consider. These values define a leg and body protection field rather than fine finger or hand detection. A model with much closer beam spacing can be selected where the protection requirement changes to finger-level detection. For an NPN finger-protection configuration with a 9 mm beam gap and 695 mm protective height, see Omron F3SJ-A0695N14.
