KMT32B Magnetic Angle Sensor
DESCRIPTION
The KMT32B is a magnetic field sensor based on the anisotropic magneto resistance effect, i.e. it is sensing
the magnetic field direction independently on the magnetic field strength for applied field strengths
H>25 kA/m. The sensor contains two parallel supplied Wheatstone bridges, which enclose a sensitive angle
of 45 degrees.
A rotating magnetic field in the surface parallel to the chip (x-y plane) will deliver two independent sinusoidal
output signals, one following a cos(2 ) and the second following a sin(2 ) function,
between sensor and field direction (see Figure 2).
