Omron F3SJ-A0245P20 Safety Light Curtain
Omron F3SJ-A0245P20 is a Safety Light Curtain designed for 20 mm hand protection across a 245 mm protective height. Its sensing field contains 16 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 supply. An M12 8-pin connector and PNP transistor outputs provide the electrical connection with the machine safety system. Within the F3SJ Series, the F3SJ-A0245P20 provides compact hand-detection coverage.

The Omron F3SJ-A0245P20 Safety Light Curtain provides 20 mm hand detection across a 245 mm protective height. Its optical field contains 16 infrared beams arranged with a 15 mm beam gap to detect opaque objects entering the protected opening. The sensing 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 model selection, the F3SJ-A0245P20 should be evaluated by its 20 mm detection capability, 245 mm protective height, 15 mm beam spacing, PNP output type, and sensing distance. These characteristics determine the size of the protected hand-detection field and required safety-system interface. A taller hand-protection configuration can be chosen where the guarded opening requires greater vertical coverage. For a 465 mm protective height with a 20 mm beam gap, see Omron F3SJ-E0465N25.
