Device for magnetic detection of moving component, has bias magnet arranged on magnetic field sensor/sensor housing, where volume design and molding of magnet is carried out by dosage and if necessary at sides by flow restriction

摘要

The device has a magnetic field sensor/sensor housing (2) with a magnetic field-sensitive sensor element (3). A bias magnet (1) is designed in the form of a dosed volume of casting compound or adhesive filled with magnetic particles and is arranged on the magnetic field sensor/sensor housing. Volume design and molding of the bias magnet is carried out by dosage and if necessary at sides by flow restriction. A depression or recess is provided in the magnetic field sensor/sensor housing for receiving the casting compound or adhesive filled with the magnetic particles.
