Omron F3SJ-A2405P20 Safety Light Curtain
Omron F3SJ-A2405P20 is a Safety Light Curtain designed for 20 mm hand protection across a 2405 mm protective height. Its sensing field contains 160 infrared beams arranged with a 15 mm beam gap to detect opaque objects entering a tall guarded machine opening. The sensing range extends from 0.2 to 7 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-A2405P20 combines fine hand detection with extensive vertical coverage.

The Omron F3SJ-A2405P20 Safety Light Curtain provides 20 mm hand detection across a 2405 mm protective height. Its sensing field contains 160 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 7 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-A2405P20 should be evaluated by its 20 mm detection capability, 2405 mm protective height, 15 mm beam spacing, PNP output configuration, and available sensing distance. These values define an extensive hand-protection field exceeding two metres in height and its electrical requirements. A substantially shorter hand and arm model can be considered where less vertical coverage and wider beam spacing are appropriate. For a 920 mm hand and arm configuration with a 25 mm beam gap, see Omron F3SJ-A0920P30.
