摘要： A distance measuring device with two magnetic field sensors and a permanent magnet and a semiconductor body is provided. The device includes a monolithically integrated evaluation circuit, and a difference signal can be determined by means of the magnetic field sensors and provides an output signal as a result of the determination. The value of the output signal based on the neutralization of a magnetic-flux-free region is a function of a distance of a ferromagnetic sensing element from the two magnetic field sensors. The semiconductor body is arranged between U-shaped pole shanks of the magnet, which is magnetized in the X direction, wherein the first magnetic field sensor is arranged in an area located between two opposing shanks of the first pole, and the second magnetic field sensor is arranged in an area located between two opposing shanks of the second pole.
