NXP KMZ49,118

KMZ49 is a high-sensitivity magnetic field sensor utilizing the magnetoresistive effect of thin-film permalloy. The sensor contains two mutually electrically isolated Wheatstone bridges, oriented at a relative angle of 45° to each other. A rotating magnetic field in the x-y plane produces two independent sinusoidal output signals: one as a function of +cos(2α) and the other as a function of +sin(2α), where α is the angle between the sensor and the direction of the magnetic field. KMZ49 is suited for high-precision angle measurement applications under low magnetic field conditions (saturation field strength 25 kA/m). The sensor operates at any frequency from 0 Hz to 1 MHz.
