Omron F3SJ-A2105P20 Safety Light Curtain
Omron F3SJ-A2105P20 is a Safety Light Curtain designed for hand protection across a 2105 mm protective height. Its sensing field contains 140 beam axes arranged with a 15 mm beam gap to provide extensive optical coverage across the protected machine opening. The sensing distance 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 electrical integration with compatible safety equipment. Within the F3SJ Series, the F3SJ-A2105P20 provides more than two metres of hand-protection coverage.

The Omron F3SJ-A2105P20 Safety Light Curtain provides hand protection across a 2105 mm protective height. Its sensing field contains 140 beam axes arranged with a 15 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 PNP 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 rating.
When choosing the F3SJ-A2105P20, the 15 mm beam spacing, 2105 mm protective height, PNP output type, M12 connector, and sensing distance should be evaluated together. These parameters define a hand-protection field exceeding two metres in vertical coverage. Related models in the supplied data use wider beam spacing where the required protection category changes to leg and body detection. For an NPN leg and body protection configuration with a 50 mm beam gap and 570 mm protective height, see Omron F3SJ-A0570N55.
