Rotary sensor for measuring shaft rotation angles has magnetic field direction sensor whose output signal is function of direction of magnetic field, e.g. magnetoresistive sensor

摘要

The device has an annular magnet (2) in whose annular space (3) a magnetic field sensor (1) is arranged, whereby the magnetic field sensor and the magnet are rotatable relative to each other. The magnetic field sensor is a magnetic field direction sensor whose output signal is a function of the direction of the magnetic field, e.g. a magnetoresistive sensor.
