Omron F3SJ-B0305N25 Safety Light Curtain
Omron F3SJ-B0305N25 is a Safety Light Curtain configured for hand protection across a 305 mm protective height. Its sensing field consists of 14 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 electrical integration with compatible machine safety equipment. Within the F3SJ Series, the F3SJ-B0305N25 provides compact hand-detection coverage with NPN outputs.

The Omron F3SJ-B0305N25 Safety Light Curtain provides hand protection across a 305 mm protective height. Its sensing field contains 14 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 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-B0305N25, the 20 mm beam spacing, 305 mm protective height, NPN output configuration, M12 connector, and sensing distance should be considered together. These values define the compact hand-protection field and control-system interface. A PNP version with the same beam count and protective height is available where the required output configuration differs. For the corresponding 305 mm PNP model using 14 beam axes and the same 20 mm beam gap, see Omron F3SJ-B0305P25.
