Allen-Bradley 845T-DZ22ACM-C Incremental Encoder

The Allen-Bradley 845T-DZ22ACM-C is an optical incremental encoder from Rockwell Automation designed for industrial environments. Housed in a Size 20 enclosure with a NEMA Type 4 rating and IP66 protection, it stands up to dust, moisture, and high-pressure washdown typical of automated production lines. It delivers 500 pulses per revolution (PPR) with a 100 kHz frequency response, enabling precise speed and position feedback for servo drives, conveyors, robotics, and other motion systems. The DZ22ACM-C variant is specified for 5 V DC operation with a maximum current draw of 150 mA, aligning with common control system power budgets. This encoder is a member of the 845T family and is used wherever robust incremental feedback and reliable enclosure protection are required in manufacturing settings.
