Automobile sensor manufacturing method uses successive molding steps for formation of pole shoe holder of coil former around pole shoe and formation of magnet holder and connector housing

摘要

The manufacturing method has a pole shoe holder (28) of a coil former (26) shaped around a pole shoe (34) in a first molding step, with the separation line between the mould halves lying outside the winding region of the coil former. The pole shoe is combined with a magnet (32) and the pole shoe holder, the pole shoe and the magnet are located in a further mould, used for forming a magnet holder (30) and a connector housing (42) about the pole shoe and the magnet. The coil former is then wound with a coil (38).
