KMZ49 Datasheet Magnetic field sensor

Manufacturer: NXP Semiconductors

General Description

The KMZ49 is a sensitive magnetic field sensor, employing the magnetoresistive effect of thin-film permalloy.

The sensor contains two galvanic separated Wheatstone bridges, at a relative angle of 45 to each other.

A rotating magnetic field in the x-y plane will produce two independent sinusoidal output signals, one a function of +cos(2) and the second a function of +sin(2),  being the angle between sensor and field direction (see Figure 2).
