Omron F3SJ-E0185N25 Safety Light Curtain
Omron F3SJ-E0185N25 is a Safety Light Curtain designed for 25 mm hand protection across a 185 mm protective height. Its optical sensing field contains 8 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the protected opening. 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 electrical interface for the machine safety system. Within the F3SJ Series, the F3SJ-E0185N25 provides compact hand-detection coverage.

The Omron F3SJ-E0185N25 Safety Light Curtain provides 25 mm hand detection across a 185 mm protective height. Its sensing field contains 8 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the protected 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 and supports operation from -10 to 55°C.
For model selection, the F3SJ-E0185N25 should be assessed by its 25 mm detection capability, 185 mm protective height, 20 mm beam spacing, NPN output configuration, and available sensing distance. These parameters define a compact hand-protection field and its electrical requirements. The supplied comparison model retains hand protection but uses a 15 mm beam gap, 160 beams, and a much greater protective height, so beam spacing, protected area, and output configuration should all be checked before comparison. For a 2405 mm hand-protection configuration using 160 beams, see Omron F3SJ-A2405P20.
