In this paper, a multiturn absolute serial encoder is designed for a space limited application such as robots using magnetic sensor instead of optical encoder. It is developed by integrating the ultra small magnetic detecting technique, interpolation technique, and serial communication technique so that the sensor can have minimum size. The usefulness of the sensor is verified with various tests.
