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
α
) and the second following a sin(2
α
) 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
