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.
