Omron F3SJ-A0720N30 Safety Light Curtain
Omron F3SJ-A0720N30 is a Safety Light Curtain designed for hand and arm protection across a 720 mm protective height. Its sensing field uses 29 beam axes arranged with a 25 mm beam gap and an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, while electrical operation is based on a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide the machine safety interface. Within the F3SJ Series, the F3SJ-A0720N30 provides 720 mm hand and arm coverage.

The Omron F3SJ-A0720N30 Safety Light Curtain provides hand and arm protection across a 720 mm protective height. Its optical field consists of 29 beam axes arranged with a 25 mm beam gap and uses an 870 nm infrared LED source. The sensing range extends from 0.2 to 9 m, and the unit operates from a 24 VDC supply. An M12 8-pin connector provides the electrical interface. Two NPN transistor outputs support maximum load currents of 300 mA each. Output short-circuit and reverse-polarity protection are specified, while the enclosure carries an IP65 protection rating and supports operation from -10 to 55°C without icing.
For model selection, the F3SJ-A0720N30 should be assessed by its 25 mm beam spacing, 720 mm protective height, NPN output configuration, M12 connector, and operating range. These specifications determine the hand and arm protection field and required electrical interface. The supplied source does not identify a specific comparison model for this unit, so selection should remain based on the stated protection category, beam count, vertical coverage, output type, connection method, and sensing distance rather than assuming equivalence with another F3SJ model.
