Omron F3SJ-B0385N25 Safety Light Curtain
Omron F3SJ-B0385N25 is a Safety Light Curtain configured for 25 mm hand protection across a 385 mm protective height. Its sensing field contains 18 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the guarded access area. The operating range extends from 0.2 to 7 m, while the unit operates from a SELV/PELV 24 VDC supply. NPN transistor outputs provide the specified electrical interface with the machine safety system. Within the F3SJ Series, the F3SJ-B0385N25 provides compact hand detection with NPN outputs.

The Omron F3SJ-B0385N25 Safety Light Curtain provides 25 mm hand detection across a 385 mm protective height. Its sensing field consists of 18 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the monitored opening. The operating range extends from 0.2 to 7 m, while the unit operates from a SELV/PELV 24 VDC ±20% supply. 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 rating.
For installation planning, the F3SJ-B0385N25 should be assessed by its 25 mm detection capability, 385 mm protective height, 20 mm beam spacing, NPN output format, and available sensing distance. These specifications define the compact hand-protection field and safety-system interface. A related hand-protection model in the supplied comparison data uses closer 15 mm beam spacing and greater vertical coverage, so beam arrangement and height should be checked carefully. For a 635 mm hand-protection configuration with 42 beams, see Omron F3SJ-A0635P20.
