Description
The ZMY20 is an extremely sensitive magnetic sensor employing the magneto-resistive effect of thin film permalloy. It allows the measurement of magnetic fields or the detection of magnetic parts. The highly sensitive and small size magnetoresistive sensors consist of a chip covered with thin film permalloy stripes. These stripes form a Wheatstone bridge, whose output voltage is proportional to the magnetic field component Hy. A perpendicular field Hx is necessary to stabilize sensor operation. This can be done 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 & speed sensing
- Metering of fluids by sensing rotation of impeller
- Traffic counting & vehicle-type sensing
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
