Omron F3SJ-A1920P55 Safety Light Curtain
Omron F3SJ-A1920P55 is a Safety Light Curtain designed for 55 mm leg and body protection across a 1920 mm protective height. Its sensing field contains 39 infrared beams positioned with a 50 mm beam gap to monitor opaque objects entering a tall protected machine opening. The sensing range extends from 0.2 to 7 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and PNP transistor outputs provide connection with the safety system. Within the F3SJ Series, the F3SJ-A1920P55 combines larger-object detection with extensive vertical coverage. For tall guarded areas, compare extended-height body protection light curtains available within Omron machine safeguarding solutions.

The Omron F3SJ-A1920P55 Safety Light Curtain provides 55 mm leg and body detection across a 1920 mm protective height. Its protective field contains 39 infrared beams arranged with a 50 mm beam gap to detect opaque objects entering the guarded machine access area. The operating range extends from 0.2 to 7 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 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.
For installation planning, the F3SJ-A1920P55 should be evaluated by its 55 mm detection size, 1920 mm protective height, 50 mm beam spacing, PNP output format, and available sensing distance. These specifications define the large body-protection field and electrical requirements for the machine safety system. The supplied source does not identify a specific comparison model for this unit, so selection should remain based on the stated detection category, number of beams, protected height, output configuration, connector type, and sensing range rather than introducing an unsupported alternative.
