Omron F3SJ-A2245N30 Safety Light Curtain
Omron F3SJ-A2245N30 is a Safety Light Curtain designed for 30 mm hand and arm protection across a 2245 mm protective height. Its sensing field contains 90 infrared beams arranged with a 25 mm beam gap to detect opaque objects entering a tall guarded machine opening. The operating range extends from 0.2 to 7 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide the safety-system interface. Within the F3SJ Series, the F3SJ-A2245N30 provides more than two metres of vertical protection.

The Omron F3SJ-A2245N30 Safety Light Curtain provides 30 mm hand and arm detection across a 2245 mm protective height. Its sensing field consists of 90 infrared beams arranged with a 25 mm beam gap to detect opaque objects entering the guarded machine area. The sensing distance extends from 0.2 to 7 m, while the unit operates from a 24 VDC ±20% supply. An M12 8-pin connector provides the electrical interface. 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.
For selection, the F3SJ-A2245N30 should be assessed by its 30 mm detection capability, 2245 mm protective height, 25 mm beam spacing, NPN output configuration, and sensing distance. These values define a tall hand and arm protection field exceeding two metres. A shorter model with the same listed hand and arm protection class and beam spacing can be considered where less vertical coverage is required, although the output configuration also differs. For a 1270 mm model using 51 beams, see Omron F3SJ-A1270P30.
