DESCRIPTION
The KMZ43T 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 one another.

A rotating magnetic field in the x-y plane will produce two independent sinusoidal output signals, one a function of +cos(2α) and the second a function of +sin(2α), α being the angle between sensor and field direction (see Fig.3). Unlike the KMZ41(1), which needs a saturation field strength of 100 kA/m, the KMZ43T is suited to high precision angle measurement applications under low field conditions (saturation field strength 25 kA/m).
