Overview
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.
Hy Hx FEATURES • Output voltage proportional to magnetic field Hy • Magnetic fields vertical to the chip level are not effective E-LINE APPLICATIONS • Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensing www.
