In one illustrative example, a magnetic storage device includes a three terminal magnetic sensor having a collector region made of a semiconductor material, a base region, and an emitter region. A traveler adjustably coupled to the applicator is moveable along a magnetized flexible guide track in order to control direction of the paint applicator as an annular paint carrying surface of the striping wheel is rolled against the surface being pinstriped. The feed-through conductor is directed around the capacitor.
