摘要： A sensor according to the invention has a U-shaped magnet having a pair of opposing portions spaced apart from each other, forming a flux-free region between the pair of opposing portions. A Hall element varies an output voltage according to the density of passing flux. A spacer regulates the positional relationship between the Hall element and the U-shaped magnet such that the Hall element is positioned in the flux-free region of the U-shaped magnet and a housing covers the spacer.
