Anderson Electric Controls 845H-NXC7938-CR1 Encoder

Allen-Bradley / Rockwell Automation 845H-NXC7938-CR1 is an incremental encoder in the 845H family, designed for industrial motion-control feedback. The Size 25 form factor integrates with 8–24 V DC supplies and draws up to 150 mA, delivering signals on the typical A and B channels for quadrature position feedback to servo drives and PLC-based controllers. The CR1 suffix identifies this specific electrical/configuration variant within the 845H line, commonly used for replacement or retrofit in systems that share the 845H footprint. This encoder provides incremental position and speed information by generating pulses as the shaft rotates, enabling precise control of machinery in automated environments. The 845H family is a long-standing Rockwell Automation solution for feedback in diverse applications, and this model's compatibility with standard 845H mounting and electrical formats facilitates integration into conveyors, packaging lines, and machine tools. For exact connectivity, mounting details, and any ancillary options, refer to Rockwell’s product literature and the 845H documentation to ensure the CR1 configuration aligns with your existing control architecture.
