Omron F3SJ-A1870P30 Safety Light Curtain
Omron F3SJ-A1870P30 is a Safety Light Curtain designed for hand and arm protection across an 1870 mm protective height. Its sensing field contains 75 beam axes positioned with a 25 mm beam gap and uses an 870 nm infrared LED light source. The sensing distance 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 machine safety interface. Within the F3SJ Series, the F3SJ-A1870P30 provides extensive vertical hand and arm coverage.

The Omron F3SJ-A1870P30 Safety Light Curtain provides hand and arm protection across an 1870 mm protective height. Its sensing field contains 75 beam axes arranged with a 25 mm beam gap and uses an 870 nm infrared LED source. 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 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 rating.
For model selection, the F3SJ-A1870P30 should be assessed by its 25 mm beam spacing, 1870 mm protective height, PNP output configuration, M12 connector, and available sensing distance. These characteristics define an extended hand and arm protection field and the required control-system interface. A related hand-protection model uses closer 15 mm beam spacing and a shorter vertical field, so the protection requirement should be checked before comparison. For an NPN hand-protection configuration with a 1025 mm protective height, see Omron F3SJ-A1025N20.
