This angle sensor is based on the brand new Giant Magneto Resistive (GMR)
technology. It is outstanding for the huge tolerances it offers to the user in
assembly.

new type
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
