Omron F3SJ-B0945N25 Safety Light Curtain
Omron F3SJ-B0945N25 is a Safety Light Curtain designed for hand protection across a 945 mm protective height. Its optical sensing field contains 46 beam axes arranged with a 20 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 and NPN transistor outputs provide the electrical interface with compatible safety equipment. Within the F3SJ Series, the F3SJ-B0945N25 provides extended hand-protection coverage with NPN outputs.

The Omron F3SJ-B0945N25 Safety Light Curtain provides hand protection across a 945 mm protective height. Its sensing field contains 46 beam axes positioned with a 20 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 electrical connection. Two NPN transistor outputs support maximum load currents of 200 mA each. Output short-circuit and power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 protection rating.
When evaluating the F3SJ-B0945N25, the 20 mm beam spacing, 945 mm protective height, NPN output format, M12 connection, and sensing distance should be considered together. These specifications define the hand-protection field and machine safety interface. A corresponding PNP configuration provides the same beam count, beam spacing, and protective height where a different output format is required. For the 945 mm PNP version using 46 beam axes, see Omron F3SJ-B0945P25.
