Product data sheet

1. Product profile

1.1 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). The KMZ49 is suited to high

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.

1.2 Features and benefits

 Accurate and reliable angle measurement
