ZMY20中文资料Magnetic Field Sensor数据手册Diodes规格书

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

应用 Application

Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensingScalar measurement for compassingAutomotive – door switches, engine position & speed sensingMetering of fluids by sensing rotation of impellerTraffic counting & vehicle-type sensing

简介

ZMY20属于传感器变送器的磁性传感器-线性罗盘（IC）。由制造生产的ZMY20磁性传感器 - 线性，罗盘（IC）该系列产品可用于将磁场强度作为一个可变数量进行测量，而相比之下，类似产品仅检测是否存在强度超过某个限值的磁场。常见的应用包括测量地球磁场，以类似于传统罗盘的方式进行定向，市面上的一些器件允许以相对于磁场的物理方向直接读取测量值。
