REV Robotics HD Hex Motors (REV-41-1291) and the Core Hex Motors (REV-41-1300) come with a magnetic quadrature encoder already installed and an appropriate cable for connecting the encoder output to the REV Robotics Control Hub (REV-31-1595) or Expansion Hub (REV-31-1153). See Table 1 and Table 2 for relevant encoder details.

The Core Hex Motor uses a 2-pin JST-VH Connector for motor power and a 4-pin JST-PH for sensor feedback from the built-in encoder. For more information on using the cables and connectors included with the Core Hex Motor, see the REV Control System - Cable and Connectors documentation. The image below has the pinout for the motor power and the encoder.
