Half turn vehicle sensor having segmented magnet

摘要

An arc magnet assembly with a virtual radial magnetization is established by placing a series of small trapezoidal-shaped magnet segments having axial magnetizations side by side to form an arc. The arc magnet assembly may be affixed to a rotating component in, e.g., a vehicle to yield a substantially linear magnetic sensor output that represents the speed and/or direction of rotation and/or position of the rotating component.
