KMZ41
Magnetic field sensor
Rev. 6 -- 18 November 2010 Product data sheet
1. Product profile
1.1 General description
The KMZ41 is a sensitive magnetic field sensor, employing the magneto-resistive effect of thin film permalloy. The sensor contains two galvanically separated Wheatstone bridges, which enclose an angle of 45 degrees. A rotating magnetic field strength > 40 kA/m (recommended field strength > 100 kA/m) in the surface parallel to the chip (x-y plane) will deliver two independent sinusoidal output signals, one following a cos(2) and the second following a sin(2) function. The sensor can be operated at any frequency between DC and 1 MHz.
1.2 Features and benefits
Accurate and reliable angle measurement Mechanical robustness, contactless principle Wear-free operation Accuracy independent of mechanical tolerances Extended temperature range
