Omron F3SJ-A0635P20 Safety Light Curtain
Omron F3SJ-A0635P20 is a Safety Light Curtain designed for 20 mm hand protection across a 635 mm protective height. Its sensing field contains 42 infrared beams arranged with a 15 mm beam gap to detect opaque objects entering the guarded 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-A0635P20 combines fine hand detection with extended vertical coverage.

The Omron F3SJ-A0635P20 Safety Light Curtain provides 20 mm hand detection across a 635 mm protective height. Its optical field contains 42 infrared beams arranged with a 15 mm beam gap to detect opaque objects entering the guarded machine opening. The operating range extends from 0.2 to 9 m, while the unit operates from a 24 VDC ±20% supply. An M12 8-pin connector provides the electrical interface. Two PNP 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.
For selection, the F3SJ-A0635P20 should be evaluated by its 20 mm detection capability, 635 mm protective height, 15 mm beam spacing, PNP output type, and available sensing distance. These specifications define the hand-protection field and its electrical connection requirements. A model from another protection category may use wider beam spacing and substantially greater vertical coverage, so detection purpose should be checked before comparison. For a leg and body protection configuration with a 1920 mm protective height and 50 mm beam gap, see Omron F3SJ-A1920N55.
