Allen-Bradley 845H-SJHZ25DNY1 is a size-25 optical incremental encoder from Rockwell Automation, providing precise rotary feedback for servo and motion-control systems. Designed for harsh industrial environments with a NEMA 4/13 enclosure, this encoder delivers 2000 pulses per revolution (PPR) and supports a 210 kHz frequency response for fast, accurate position signaling. Used in applications such as high-speed conveyors, packaging lines, and automated machining, it integrates with Rockwell/Allen-Bradley controllers to enable reliable motion control and repeatable positioning.
