What is the purpose of a shaft encoder?

The primary purpose of a shaft encoder is to convert the mechanical rotational or linear motion of a shaft into electrical signals that a controller or computer can understand. This enables the system to track information such as the shaft's position, speed, and direction—key data for the precise control of many machines.

For instance, in a CNC (Computer Numerical Control) machine tool, the shaft encoder on the spindle informs the system about the spindle's rotational speed and position, allowing the machine to cut materials with high precision. In robots, encoders mounted on motor shafts assist the robot's arms in moving to the correct positions.

Here, the shaft encoders from Shanghai Hengxiang stand out due to their durability. They feature a sealed design, which prevents dust and moisture—common in factory environments—from easily entering and damaging internal components. Additionally, Hengxiang's shaft encoders come with a wide range of torque and speed ratings, so you can find encoders suitable for various machines, from small household appliances to large industrial equipment.

Tip: When selecting a shaft encoder, ensure that the shaft diameter matches your machine. Hengxiang provides detailed specifications on their website.
