Allen-Bradley 847H-DN2D-AF01000 Incremental Optical Encoder

Allen-Bradley 847H-DN2D-AF01000 Incremental Optical Encoder delivers high-resolution position feedback with 1000 pulses per revolution in a compact, rugged package. It features a standard square flange and a 3/8-inch diameter shaft with a flat for secure mounting to motors or drives. The encoder provides open-collector A, B, and Z (index) outputs at 8–30 V DC through a 7-pin MS-style connector, enabling straightforward integration with Rockwell Automation controllers. Rated with a 1000 PPR resolution and built for Rockwell ecosystems, this model is listed as Active by the manufacturer, with an estimated lead time of 5 days and a 1-year standard warranty. The unit is manufactured in the United States and is designed to deliver reliable incremental feedback for precise speed and position sensing in automation and motion-control applications.
