Potentiometer or Encoder – What is the difference?

A potentiometer and an encoder are both electromechanical devices used to measure position; however, the potentiometer outputs analog signals while the encoder outputs digital signals. Generally, the potentiometer has a shorter life and lower accuracy than the encoder but output more continuous analogue output.
