Omron F3SJ-A1955P20 Safety Light Curtain
Omron F3SJ-A1955P20 is a Safety Light Curtain configured for hand protection across a 1955 mm protective height. Its optical field uses 130 beam axes arranged with a 15 mm beam gap, providing closely spaced sensing coverage across a tall 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 and PNP transistor outputs provide the electrical interface. Within the F3SJ Series, the F3SJ-A1955P20 combines fine hand detection with extensive vertical coverage.

The Omron F3SJ-A1955P20 Safety Light Curtain provides hand protection across a 1955 mm protective height. Its optical field consists of 130 beam axes positioned with a 15 mm beam gap and uses an 870 nm infrared LED light source. The sensing range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector provides electrical integration with compatible safety equipment. Two PNP 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 protection rating.
For selection, the F3SJ-A1955P20 should be assessed by its 15 mm beam spacing, 1955 mm protective height, PNP output configuration, M12 connection, and operating distance. These values define the extensive hand-protection field and its safety-system interface. Related models in the supplied data belong to different protection categories with either finer or wider beam spacing. For a PNP finger-protection configuration with a 9 mm beam gap and 263 mm protective height, see Omron F3SJ-A0263P14.
