Building the Right Foundation with a Hollow Shaft Encoder！

Every rotary encoder works by being mounted to a motor by a shaft. The encoder has a fixed housing with a rotor wheel (either a detached component or integrated within the housing with bearings) which revolves around the shaft. Those rotations are the basis for determining speed, positioning, and other motion information.

About the single most important thing that distinguishes between rotary encoder designs is the mounting configuration. The inner workings of the encoder may all be the same – absolute or incremental, optical or magnetic – but the simple decision on how to attach the encoder can make a major difference in the physical design of your application.

A hollow shaft encoder mount is one of the lowest-overhead, lowest-stress options for an encoder. This design offers simplicity because a hollow shaft encoder is compact, adjustable, and versatile.
