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.
Application
- Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensing
- Scalar measurement for compassing
- Automotive - door switches, engine position and speed sensing
- Metering of fluids by sensing rotation of impeller
- Traffic counting & vehicle-type sensing
- Measurement of current in a conductor without connection
Features
- Output voltage proportional to magnetic field Hy
- Magnetic fields vertical to the chip level are not effective
