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(2 ) and the second a function of +sin(2 ),
angle between sensor and field direction (see
precision angle measurement applications under low field conditions (saturation field
strength 25 kA/m).
The sensor can be operated at any frequency between 0 Hz and 1 MHz.
