What is encoder?

In general an encoder is a device that converts data from one format to another.

Linear vs. rotary encoders

We classify linear and rotary encoders according to the type of movement.

Incremental vs. absolute encoders

The difference between incremental and absolute encoders can be seen as the difference between stopwatch and clock.

Encoder resolution, accuracy and repeatability: What's the difference?

The resolution is the smallest movement detected by the encoder. It is measured differently depending on the type of encoder.

The accuracy is a measure of how close the output is to where it should be.

Repeatability is the maximum difference between different measurements taken at the same actual position.
