Q62705-K5002

The GMR S 4 is an angle sensor based on sputtered metallic multilayer technology. The

outstanding feature of this magnetic sensor is the fact that it is sensitive to the

orientation of the magnetic field and not to its intensity as long as the field is in a range

between 5 … 15 kA/m. This means, the signal output of this sensor is independent

of the sensor position relative to the magnet in lateral, axial or rotational direction

in the range of several millimeters. Optimum results are achieved by using magnetic

targets like permanent magnets or magnetic pole-wheels. There is no need for a

biasing magnet! Due to the linear change of both, basic and field dependent part of the

resistance vs. temperature, simple and efficient electronic compensation of T_C(R, ∆R) is

possible.
