Omron F3SJ-A0620N55 Safety Light Curtain
Omron F3SJ-A0620N55 is a Safety Light Curtain configured for leg and body protection with 55 mm detection capability. Its sensing field consists of 13 infrared beams arranged with a 50 mm beam gap across a 620 mm protective height. The unit detects opaque objects within a 0.2 to 9 m sensing range and 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-A0620N55 provides a 620 mm body-detection configuration.

The Omron F3SJ-A0620N55 Safety Light Curtain provides 55 mm leg and body detection using 13 infrared beams positioned with a 50 mm beam gap. This arrangement creates a 620 mm protective height while supporting a sensing distance of 0.2 to 9 m. The unit operates from 24 VDC and uses an M12 8-pin connector. Two NPN transistor outputs are rated for a maximum load current of 300 mA each. The enclosure is rated IP65 and operates from -10 to 55°C without icing.
The F3SJ-A0620N55 should be selected according to its 55 mm detection size, 620 mm protective height, 50 mm beam spacing, NPN output format, and operating range. These specifications distinguish it from finer hand- and finger-protection models. For greater vertical coverage while retaining the same 50 mm beam gap and leg/body protection, see Omron F3SJ-A1020N55.
