ZMZ20M
MAGNETIC FIELD SENSORS
DESCRIPTION
The ZMZ20M is an extremely sensitive magnetic field sensor in a 4 pin
E-line package employing the magneto-resistive effects of thin film
Permalloy. It allows the measurement of magnetic fields or the detection
of metallic parts. The sensor consists of a chip covered with Permalloy
stripes which form a Wheatstone bridge, whose output voltage is
proportional to the magnetic field component Hy. A perpendicular field Hx
is necessary to suppress the hysteresis and this is provided by an internal
permanent magnet.
