Allen-Bradley 845H-SJHZ14CJY1C Rotary Encoder

Allen-Bradley 845H-SJHZ14CJY1C is an incremental optical encoder from Rockwell Automation's 845H family, designed to deliver reliable rotational position feedback for automated motion systems in manufacturing environments. This variant operates from a 5 V DC supply, aligning with common low-voltage encoder configurations used in servo axes, CNCs, and PLC-controlled equipment. As part of the 845H line, it provides encoder position signals that enable closed-loop control when paired with Allen-Bradley servo drives and controllers, helping to regulate speed, positioning, and synchronization on conveyors, packaging lines, and machining centers. Availability and exact electrical interface (A/B/Z outputs, connector type, and pulses per revolution) vary by sub-model; confirm the CJY1C variant with the supplier to ensure compatibility with your drive or controller.
