Allen-Bradley 845H-Sjhz24Cny1C Incremental Encoder

The Allen-Bradley 845H-SJHZ24CNY1C is a size-25 optical incremental encoder from Rockwell Automation that provides high-resolution shaft-position feedback for precision motion control in industrial automation lines. Designed for industrial environments, its enclosure carries a NEMA 4/Type 13 rating, guarding the optics and electronics from dust, moisture, and incidental splashes while maintaining reliable operation at speed. Key performance figures commonly associated with this 845H variant include a 210 kHz frequency response and 1000 pulses per revolution, enabling stable counting and synchronization with PLCs and servo drives across moderate-speed applications. The unit is part of the 845H family, aligning with Rockwell catalog conventions and supporting installation in standard 25mm-size mounting footprints. The kit is delivered with installation instructions to simplify mounting, alignment, and electrical hookup, ensuring proper integration into existing Rockwell Automation configurations and predictable performance in industrial motion systems.
