ABSTRACT:
A position sensing device is disclosed including an assembly of a Hall effect generator element shiftably supported relatively to a permanently magnetizable element. Each such Hall effect generator element being randomly chosen from an inventory of parts having wide tolerance limits of Hall effect output under like magnetic flux influence; and each magnetizable element from an inventory having a widely varying magnetic capability after exposure to like magnetizing influence. The magnetization of the magnetizable element of each such assembly being imparted thereto under control of the Hall effect output of the specific Hall effect generator in the assembly with the result that every position sensing device so assembled can be made to produce substantially identical Hall effect output in each relative position of said elements.
