Magnetic Field Angle Sensor
Description
The ZMT32 is a thin film permalloy magnetic
field sensor, which contains two galvanic
isolated
precision angle measurement applications
under low field conditions. This angle sensor
is based on the anisotropic magnetoresistive
effect (AMR). The two internal (V
bridges enclose a relative sensitive angle of
45 degrees. The input field is a rotating
magnetic field in the chip plane (parallel to
the surface of package). This rotating field will
make available two independent sinusoidal
output signals with the following relationship

The precise ZMT32 works with low field
applications (H
than similar devices. The ultimate output signal
quality depends on the external magnetic
material and on the mechanical realization.
The ZMT32 is a passive part and the Arc-
Tangent interpolation needs external signal
processing. Typical areas of application are
angle and speed measurement.
Applications
angle and angular velocity measuring systems
absolute angle and angle change
automotive
control, pedal positioning, etc
contactless rotary switches and potentiometer
automatic adjustment
