SEMICO NDUC TORS

DESCRIPTION

The ZMZ20 is an extremely sensitive magnetic field sensor ina4pin

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 can be provided by

using a small permanent magnet.

FEATURES

hysteresis by the auxiliary magnetic field Hx

APPLICATIONS

interlocks, proximity detectors, machine tool sensing
