Abstract:
1. A measuring device for contactless detection of a ferromagnetic object, comprising at least one magnet; a magnetic field-sensitive element arranged so that an air gap is provided between the magnetic field-sensitive element and the ferromagnetic object; a soft-magnetic component located between the magnet and the magnetic field-sensitive element on a face of the magnet which points in a direction of the ferromagnetic object to be detected, the soft-magnetic component being formed as a cap-shaped element that has a recess that is open in a direction away from the magnetic field-sensitive element to house said magnet and opening that is open in a direction of the magnetic field-sensitive element, said soft-magnetic component having a first side wall defining said recess and also having a portion which forms a second side wall defining the opening, said first side wall and said second side wall being in alignment with one another.
