Omron F3SJ-E1025N25 Safety Light Curtain
Omron F3SJ-E1025N25 is a Safety Light Curtain configured for 25 mm hand protection across a 1025 mm protective height. Its protective field contains 50 infrared beams positioned with a 20 mm beam gap to detect opaque objects entering the monitored 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 two outputs supporting 200 mA maximum load current. Within the F3SJ Series, the F3SJ-E1025N25 combines hand detection with more than one metre of vertical coverage.

The Omron F3SJ-E1025N25 Safety Light Curtain provides 25 mm hand detection across a 1025 mm protective height. Its protective field contains 50 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 ±20% supply. Two NPN transistor outputs support maximum load currents of 200 mA each, with a residual voltage of 2 V maximum and leakage current of 1 mA maximum. Output short-circuit and power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 rating. The emitter current is specified at 63 mA maximum and the receiver current at 48 mA maximum.
When selecting the F3SJ-E1025N25, the 25 mm detection capability, 1025 mm protective height, 20 mm beam spacing, NPN output format, and sensing distance should be considered together. These values define the hand-protection field and its electrical interface. The supplied comparison model belongs to the leg and body protection category and uses a 50 mm beam gap with 24 beams across a 1170 mm protective height. Because the detection category differs, the beam arrangement and protection requirement should be checked before selection. For that leg and body configuration, see Omron F3SJ-A1170N55.
