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.
