Description
he ZMZ20 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 can be provided by using a small 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 and vehicle-type sensing
- Measurement of current in a conductor without connection
Features
- Output voltage proportional to magnetic field Hy
- Adjustment of sensitivity and suppression of hysteresis by the auxiliary magnetic field Hx
- Magnetic fields vertical to the chip level are not effective
