Preliminary specification
Magnetic field sensor
DESCRIPTION The KMZ41 is a sensitive magnetic field sensor, employing the magnetoresistive effect of thin-film permalloy. The sensor contains two galvanic separated Wheatstone bridges. Its properties enable this sensor to be used in angle measurement applications under strong field conditions. A rotating magnetic field strength > 40 kA/m (recommended field strength > 100 kA/m) in the x-y plane will deliver a sinusoidal output signal. The sensor can be operated at any frequency between DC and 1 MHz.
