How to distinguish potentiometers and encoders

      1. Potentiometer and encoder rotation angle is different

      Potentiometer and encoder, there is an essential difference, the most direct resolution method is: rotate a bit, if the rotation angle is less than one turn is the potentiometer, if it can rotate 360 ​​degrees infinitely is the encoder.

      2. Potentiometer and encoder work differently

      Potentiometer: The principle is to change the resistance output by rotation. Because there is a resistor inside the potentiometer, the resistor has an angle limit, so the rotation angle is less than 360 degrees.

       Encoder: The principle is to change the pulse output by rotation, because the inside of the encoder is a contact, the pulse is changed by turning on and off, so it can rotate infinitely 360 degrees.
