Abstract
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; and a soft-magnetic component located between 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, said soft-magnetic component being formed as a cap-shaped element that has a recess that is open in a direction away from said magnetic field-sensitive element to house the magnet and an opening that is open in a direction of the magnetic field-sensitive element, to house the magnet and opening that is open in a direction of the magnetic field-sensitive element, the soft-magnetic component having a first side wall defining said recess and also having a portion which forms a second side wall defining said opening, said first side wall and said second side wall being in alignment with one another.
