Allen-Bradley 845T-DZ32ECN Rotary Encoder

The Allen-Bradley 845T-DZ32ECN is a rugged incremental rotary encoder that provides precise rotational feedback for industrial motion systems. It operates from an 11-24 VDC supply and delivers 1000 pulses per revolution, offering high-resolution feedback for speed measurement, position tracking, and closed-loop control when connected to compatible Rockwell Automation controllers. As a member of the 845T family, the DZ32ECN designation identifies a specific model variant within this legacy lineup, designed for integration with Allen-Bradley hardware and Rockwell PLCs and motion controllers. In practice, technicians attach it to a motor or driven shaft to supply reliable incremental data used by motion controllers to regulate speed, torque, and positioning in applications such as packaging lines, conveyors, automated manufacturing cells, and robotic systems. The 1000 PPR resolution supports finer control loops and smoother operation in medium- to high-speed applications, while the 11–24 VDC input range keeps the device compatible with standard industrial power rails and control cabinet wiring.
