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.

Features

  • Output voltage proportional to magnetic field Hy.
  • Magnetic fields vertical to the chip level are not effective E-LINE.

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.
