DESCRIPTION
The KMZ50 is an extremely sensitive magnetic field
sensor, employing the magnetoresistive effect of thin-film
permalloy. The sensor contains one magnetoresistive
Wheatstone bridge and integrated set/reset conductors.
With the integrated set/reset conductor the orientation of
sensitivity may be set or changed (flipped). A short current
pulse on this conductor is needed to recover (set) the
sensor after exposure to strong disturbing magnetic fields.
A negative current pulse will reset the sensor to reversed
sensitivity. By use of periodically alternated flipping pulses
and a lock-in amplifier, output will become independent of
sensor and amplifier offset.
