Arnold is prepared to supply the full range of magnetic products into this marketplace. Contact us to find out how we can assist you.
Click to enlarge	Most automotive devices fall into three catagories: sensors, motors, and actuators. The computor that controls automotive functions uses the sensors as its ears, eyes and sense of touch. When input information is processed, output is directed to motors and actuators.
