Omron F3SJ-A1025N20 Safety Light Curtain
Omron F3SJ-A1025N20 is a Safety Light Curtain configured for hand protection across a 1025 mm protective height. Its optical field consists of 68 beam axes positioned with a 15 mm beam gap to monitor opaque objects entering the protected opening. The sensing distance extends from 0.2 to 9 m, and the unit operates from a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide connection with compatible machine safety equipment. Within the F3SJ Series, the F3SJ-A1025N20 combines close beam spacing with extended vertical coverage.

The Omron F3SJ-A1025N20 Safety Light Curtain provides hand protection across a 1025 mm protective height. Its sensing field contains 68 beam axes arranged with a 15 mm beam gap and uses an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector provides electrical connection with the safety system. Two NPN transistor outputs support maximum load currents of 300 mA each. Output short-circuit and power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 rating.
When selecting the F3SJ-A1025N20, the 15 mm beam spacing, 1025 mm protective height, NPN output format, M12 connection, and sensing distance should be considered together. These specifications define the hand-protection field and its electrical requirements. Other F3SJ models use wider or narrower beam spacing when the protection category changes from hand detection to body or finger protection. For an NPN leg and body protection configuration with a 50 mm beam gap and 570 mm protective height, see Omron F3SJ-A0570N55.
