General description

The KMZ41 is a sensitive magnetic field sensor, employing the magneto-resistive effect of thin film permalloy. The sensor contains two galvanically separated Wheatstone bridges, which enclose an angle of 45 degrees.

A rotating magnetic field strength > 40 kA/m (recommended field strength > 100 kA/m) in the surface parallel to the chip (x-y plane) will deliver two independent sinusoidal output signals, one following a cos(2α) and the second following a sin(2α) function.

The sensor can be operated at any frequency between DC and 1 MHz.

Features and benefits

■ Accurate and reliable angle measurement

■ Mechanical robustness, contactless principle

■ Wear-free operation

■ Accuracy independent of mechanical tolerances

■ Extended temperature range

KMZ41属于传感器，变送器 > 磁性传感器 - 线性，罗盘（IC）。恩智浦半导体公司制造生产的KMZ41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。
