The KMT32B is a magnetic field sensor based on the anisotropic magnetoresistance effect. 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(2α) law.
The KMT32B is a magnetic angle sensor based on the anisotropic magnetoresistance effect. It contains two parallel Wheatstone bridges that provide sinusoidal outputs for angles up to 45°, suitable for high‑precision angle measurement under low magnetic field conditions.
