The hollow shaft encoder is also known as a hollow sensor and a hollow sensor. It is a very flexible encoder. It is characterised by its compactness and ease of adjustment and is suitable for a wide range of applications. Each rotary encoder must be connected to the load by means of a shaft, either as a detachable part or as a bearing connected to the housing. Regardless of the principle used in the encoder, the method of mounting the omron encoder(B&R X20IF1063 Communication Module, Allen Bradley 1769-OB16 Output Module, Siemens 6DD1600-0AJ0 CPU) is a factor that should not be overlooked.

The shaft diameter of the hollow shaft encoder applies to the extension shaft of the motor. The concentric shaft of the motor passes through the middle space of the encoder and the bottom clamping ring is tightened and attached. This means that the hollow shaft encoder does not have to be perfectly sized for the protruding shaft of the motor and no additional parts are required to increase the size during installation. The clamping method and mounting bracket construction of the hollow shaft encoder makes it very easy to adjust its position and absorb vibrations and shocks from the load, and also increases the service life of the hollow shaft encoder.
