ZMY20数据手册分立半导体产品的二极管-齐纳-单规格书PDF

描述 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.

特性 Features

Output voltage proportional to magnetic field HyAdjustment of sensitivity and suppression of hysteresis by the auxiliary magnetic field HxMagnetic fields vertical to the chip level are not effective
