Omron F3SJ-A1055N14 Safety Light Curtain
Omron F3SJ-A1055N14 is a Safety Light Curtain designed for finger protection across a 1055 mm protective height. Its protective field contains 116 beam axes arranged with a 9 mm beam gap, providing dense optical coverage across a tall guarded machine opening. The operating range extends from 0.2 to 9 m, while the unit operates from 24 VDC. An M12 8-pin connector and NPN transistor outputs provide the electrical interface with the safety system. Within the F3SJ Series, the F3SJ-A1055N14 provides fine finger-level detection beyond one metre in height.

The Omron F3SJ-A1055N14 Safety Light Curtain provides finger protection across a 1055 mm protective height. Its optical field contains 116 beam axes arranged with a 9 mm beam gap to provide dense sensing coverage across the guarded machine opening. 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 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 model selection, the F3SJ-A1055N14 should be assessed by its 9 mm beam spacing, 1055 mm protective height, NPN output configuration, M12 connector, and available sensing distance. These parameters define the fine finger-protection field and distinguish the model from wider-spaced hand and body configurations. Related models may provide different protection categories or substantially different vertical coverage, so beam spacing and output format should be checked before selection. For a 620 mm leg and body protection configuration with a 50 mm beam gap, see Omron F3SJ-A0620P55.
