2.3.2 Automatic centering potentiometer

The potentiometer fixed on the steering gear box output shaft should be a 5K
conductive plastic potentiometer. A multi-turn potentiometer is suggested to ensure
negligible mechanical play.
The feedback angle potentiometer should rotate approximately ensure 80% of its total
travel, corresponding to 180 degrees of steering angle. The greater the travel, the
better the resolution and accuracy.
