Overview
DISCRETE SEMICONDUCTORS DATA SHEET M3D315 KMZ43T Magnetic field sensor Product specification Supersedes data of 2003 Mar 26 2003 Sep 15 Philips Semiconductors Product specification Magnetic field sensor 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).
The sensor can be operated at any frequency between DC and 1 MHz.
