Omron F3SJ-A0970N55 Safety Light Curtain
Omron F3SJ-A0970N55 is a Safety Light Curtain configured for leg and body protection across a 970 mm protective height. Its sensing field contains 20 beam axes positioned with a 50 mm beam gap and uses 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 connection with compatible safety equipment. Within the F3SJ Series, the F3SJ-A0970N55 provides nearly one metre of body-protection coverage.

The Omron F3SJ-A0970N55 Safety Light Curtain provides leg and body protection across a 970 mm protective height. Its sensing field contains 20 beam axes arranged with a 50 mm beam gap and uses an 870 nm infrared LED light source. The operating range extends from 0.2 to 9 m, while 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 power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 protection rating.
When choosing the F3SJ-A0970N55, the 50 mm beam spacing, 970 mm protective height, NPN output format, M12 connection, and sensing distance should be evaluated together. These specifications define a body-protection field rather than fine hand or finger detection. Related NPN configurations with closer beam spacing are available when the required protection category changes to hand and arm detection. For a 1195 mm hand and arm model with a 25 mm beam gap and NPN outputs, see Omron F3SJ-A1195N30.
