How Does an Encoder Work?

Answer

A mechanical encoder has a disc that turns while a row of sliding contacts wipes against the disc. A row of sliding contacts is fixed to a stationary object so that each contact wipes against the metal disc at a different distance from the shaft. As the disc rotates with the shaft, some of the contacts touch metal, while others fall in the gaps where the metal has been cut out. The metal sheet is associated to a source of electric current, and each contact is connected to a separate electrical sensor. The metal pattern is designed so that every possible situation of the axle creates a exclusive binary code in which some of the contacts are connected to the current source.

An encoder is a sensor that detects the change of position with accuracy. An example of an encoder would be a tachometer that detects the rpm of a car engine.
