Magnetoresistive Sensor 2-Axis 5.7(mV/V)/(kA/m) 4-Pin SOT-223 T/R

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 magneto resistive 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.

• 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
