Omron F3SJ-A0945N30 Safety Light Curtain
Omron F3SJ-A0945N30 is a Safety Light Curtain configured for 30 mm hand and arm protection across a 945 mm protective height. Its sensing field contains 38 infrared beams arranged with a 25 mm beam gap to monitor opaque objects entering the guarded machine area. The operating range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide the electrical interface. Within the F3SJ Series, the F3SJ-A0945N30 provides extended hand and arm detection with NPN outputs.

The Omron F3SJ-A0945N30 Safety Light Curtain provides 30 mm hand and arm detection across a 945 mm protective height. Its sensing field contains 38 infrared beams arranged with a 25 mm beam gap to detect opaque objects entering the guarded machine opening. The operating range extends from 0.2 to 9 m, and the unit operates from a 24 VDC ±20% supply. An M12 8-pin connector provides the electrical interface. Two NPN transistor outputs support a maximum load current of 300 mA each. Output short-circuit and reverse-polarity protection are specified, while the enclosure carries an IP65 rating.
For selection, the F3SJ-A0945N30 should be evaluated by its 30 mm detection size, 945 mm protective height, 25 mm beam spacing, NPN output configuration, and operating distance. These values define the hand and arm protection field and electrical compatibility with the safety system. A similar model can provide almost the same protected height while changing the electrical output configuration from NPN to PNP. For a 920 mm hand and arm protection model with a 25 mm beam gap, see Omron F3SJ-A0920P30.
