基于AMR (各向异性磁阻)技术的角度和速度传感器以高精度的性能,客户可灵活选择稀土材料或低成本的铁氧体磁铁特点,适用于轮速测量、电子节气门、发动机管理、主动悬挂、底盘控制、电子助力转向等应用,有效控制系统成本。KMA系列磁阻(MR)角度传感器采用真正的角度测量方法,能够准确、可靠运行,不会导致磁场强度变化。磁阻传感器工作时几乎不受因使用寿命、温度和机械应力变化而造成的磁偏移和磁漂移的影响。通过卓越的线性度和温度漂移行为,它们能够提供高精度的角度测量。与采用其他传感方法的器件相比,我们的磁阻角度传感器具有明显的优势。磁阻传感器提供的输出信号基本上与磁铁容差、磁铁温度系数、磁铁传感器距离和定位容差无关。
