Device for contact-less detection of relative position of fastening rail and seat rail in passenger car, has Hall sensor, where magnetic field has magnetization vector enclosing acute angle with normals on region of Hall sensor

摘要

The device has a sensor device (5) arranged at a movable component (2) or a stationary component and comprising a Hall sensor (8) with a laminar magnetic field-sensitive region (9) that is turned towards a magnetic field generating device (3). The magnetic field generating device is arranged in a magnet housing (4) and generates magnetic field with a magnetization vector (J) that encloses an acute angle with normals on the magnetic field-sensitive region. The magnetic field generating device has permanent magnets (7) whose polarities are opposite to each other.
