Non-Contact Potentiometer

P1.jpg

Non-Contact Potentiometer is made of photoelectric sensor, a new type optical sensor based on the non-friction magnetic induction principle to turn the mechanical rotation angle displacement of the shaft into an analog signal. It can measure the little change in angle and the angular displacement in 360°C continuous rotation. It is non-contact, has high sensitivity, reliability and extra long life.
