Basic Knowledge of Rotary Position Sensors
- Principle -

The output voltage of contact type rotary position sensor is proportional to the rotational angle of a rotor in potentiometer fashion.
Output voltage fluctuates from change in resistance due to the rotation of the rotor.The rotational angle can be easily derived by measureing this voltage.
