Omron F3SJ-E0785N25 Safety Light Curtain
Omron F3SJ-E0785N25 is a Safety Light Curtain configured for 25 mm hand protection across a 785 mm protective height. Its protective field contains 38 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the guarded machine opening. The sensing 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 with the safety system. Within the F3SJ Series, the F3SJ-E0785N25 provides 785 mm vertical hand-protection coverage.

The Omron F3SJ-E0785N25 Safety Light Curtain provides 25 mm hand detection across a 785 mm protective height. Its optical field consists of 38 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the guarded access area. The sensing 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.
When selecting the F3SJ-E0785N25, the 25 mm detection capability, 785 mm protective height, 20 mm beam spacing, NPN output configuration, and operating distance should be considered together. These specifications define the hand-protection field and electrical requirements. The supplied comparison model belongs to the finger-protection category and uses a much closer 9 mm beam gap, so it represents a different detection requirement rather than a direct equivalent. For a 245 mm finger-protection configuration using 26 beams, see Omron F3SJ-A0245P14.
