Omron F3SJ-E0545N25 Safety Light Curtain
Omron F3SJ-E0545N25 is a Safety Light Curtain designed for 25 mm hand protection across a 545 mm protective height. Its sensing field contains 26 infrared beams arranged with a 20 mm beam gap to detect opaque objects entering the monitored machine 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 specified electrical interface with the safety system. Within the F3SJ Series, the F3SJ-E0545N25 combines 25 mm detection with 545 mm vertical coverage.

The Omron F3SJ-E0545N25 Safety Light Curtain provides 25 mm hand detection across a 545 mm protective height. Its sensing field consists of 26 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the guarded machine area. 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-E0545N25 should be assessed by its 25 mm detection capability, 545 mm protective height, 20 mm beam spacing, NPN output configuration, and operating distance. These values define the hand-protection field and its electrical requirements. The supplied comparison models belong to different protection categories and use wider beam spacing, so detection class and protected height should be checked before comparison. For a 1020 mm leg and body protection configuration using 21 beams and a 50 mm beam gap, see Omron F3SJ-A1020N55.
