Allen-Bradley 845D-SJDZ24AGFW4 is a 1-turn optical absolute encoder that provides direct shaft-position feedback for industrial automation. The unit comes in a size 25 package with a NEMA 4 enclosure, suited for damp or dusty environments, and delivers 1024 counts per revolution in binary output for precise position sensing. This single-turn encoder from the 845D family typically operates from an unregulated 8–24 V DC supply, making it compatible with standard factory power rails and Rockwell Automation control systems.
