GMRS6 General Description
The GMR S6 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 TC (R, R) is possible.
