Omron F3SJ-A0461N14 Safety Light Curtain
Omron F3SJ-A0461N14 is a Safety Light Curtain designed for finger protection across a 461 mm protective height. Its optical field consists of 50 beam axes arranged with a 9 mm beam gap, using an 870 nm infrared LED light source for fine intrusion detection. The sensing range extends from 0.2 to 9 m, and the unit operates from 24 VDC. An M12 8-pin connector and NPN transistor outputs provide the electrical interface with the machine safety system. Within the F3SJ Series, the F3SJ-A0461N14 combines close beam spacing with extended finger-level coverage.

The Omron F3SJ-A0461N14 Safety Light Curtain provides finger protection across a 461 mm protective height. Its sensing field consists of 50 beam axes positioned with a 9 mm beam gap and uses an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, and 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 a maximum load current 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-A0461N14, the 9 mm beam spacing, 461 mm protective height, NPN output configuration, M12 connection, and sensing range should be evaluated together. These parameters define the fine protective field and electrical requirements of the machine safety circuit. A model with larger beam spacing should only be considered when the required protection category changes from finger detection to hand or arm detection. For an NPN hand and arm model with a 25 mm beam gap and 1395 mm protective height, see Omron F3SJ-A1395N30.
