Omron F3SJ-A0545P20 Safety Light Curtain
Omron F3SJ-A0545P20 is a Safety Light Curtain designed for 20 mm hand protection across a 545 mm protective height. Its sensing field uses 36 infrared beams with a 15 mm beam gap to detect opaque objects within a 0.2 to 9 m operating range. Power is supplied at 24 VDC, while an M12 8-pin connector and PNP transistor outputs provide the electrical connection. Within the F3SJ Series, the F3SJ-A0545P20 provides a PNP-output configuration with 545 mm coverage.

The Omron F3SJ-A0545P20 Safety Light Curtain provides 20 mm hand detection using 36 infrared beams arranged with a 15 mm beam gap. The sensing field covers a 545 mm protective height and operates across a distance of 0.2 to 9 m. The unit operates from 24 VDC and uses an M12 8-pin connector. 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.
The F3SJ-A0545P20 should be selected by considering its 20 mm detection capability, 545 mm protected height, 15 mm beam spacing, PNP output format, and sensing distance. These parameters determine the size and vertical extent of the protected field. For greater protective height with hand detection, see Omron F3SJ-E0705N25, which provides a 705 mm protective height.
