Encoder definition

In general an encoder is a device or process that converts data from one format to another. In position sensing, an encoder is a device which can detect and convert mechanical motion to an analog or digital coded output signal. More specifically, it measures the position, while velocity, acceleration and direction can be derivated from the position in either linear or rotary movement.

Different functionality of encoders comes from different physical principles of operation, outputs, communication protocols etc.
