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.Aperpendicular field Hx
is necessary to suppress the hysteresis and this is provided by an internal
permanent magnet.
Feature(s)
Output voltage proportional to magnetic field HyMagnetic fields vertical to the chip level are not effective
Application(s)
Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensingScalar measurement for compassingAutomotive - door switches, engine position and speed sensingMetering of fluids by sensing rotation of impellerTraffic counting & vehicle-type sensingMeasurement of current in a conductor without connection
