Omron F3SJ-A1805N20 Safety Light Curtain
Omron F3SJ-A1805N20 is a Safety Light Curtain configured for hand protection across an 1805 mm protective height. Its optical field uses 120 beam axes arranged with a 15 mm beam gap and an 870 nm infrared LED light source to monitor the guarded 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 NPN transistor outputs provide connection with compatible machine safety equipment. Within the F3SJ Series, the F3SJ-A1805N20 combines close beam spacing with tall vertical coverage.

The Omron F3SJ-A1805N20 Safety Light Curtain provides hand protection across an 1805 mm protective height. Its optical field contains 120 beam axes arranged with a 15 mm beam gap and uses an 870 nm infrared LED light source. The sensing range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector provides electrical connection with compatible safety equipment. 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 selecting the F3SJ-A1805N20, its 15 mm beam spacing, 1805 mm protective height, NPN output format, M12 connection, and operating distance should be considered together. These parameters define the tall hand-protection field and its electrical requirements. Related models in the supplied data use different beam spacing where the protection category changes from hand detection to hand and arm or finger protection. For an NPN hand and arm model with a 25 mm beam gap and 1195 mm protective height, see Omron F3SJ-A1195N30.
