Allen-Bradley 847H-DN2D-RE00500 Incremental Encoder

Allen-Bradley 847H-DN2D-RE00500 is a 2.5-inch housing incremental optical encoder that delivers precise rotary feedback for industrial automation. It provides a 500 pulses-per-revolution (PPR) quadrature output with an index (Z) signal and operates from a supply range of 8 to 30 V DC using open-collector A, B, and Z outputs. The unit features a 3/8-inch diameter shaft with a flat for secure coupling, a standard square mounting flange, and a radial exit MS-style 7-pin connector with a mating cable for straightforward integration with servo drives and motion controllers. Typical applications include servo feedback for CNC machines, packaging lines, and other automated systems that require reliable speed and position sensing.
