Allen-Bradley 845N-SJDN3-CRN1 Optical Incremental Encoder

Allen-Bradley 845N-SJDN3-CRN1 is a Series C optical incremental encoder from Rockwell Automation designed to provide precise position feedback in industrial automation. This model is used with servo and motion-control systems to generate reliable pulse information for speed and position monitoring on conveyors, packaging lines, robotics, and machine tools. The SJDN3-CRN1 suffix denotes the specific connector and mounting variant within the 845N family, aligning with Rockwell automation interface standards for straightforward integration with compatible drives and PLCs. This encoder is designed for use in demanding industrial environments where accurate incremental feedback supports closed-loop control and improved process performance.
