SO 8 KMZ49 Magnetic field sensor Rev. 1 — 31 October 2011 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.
