HAL817UT-A数据手册TDK-Micronas中文资料规格书

描述 Description

HAL 810和HAL 817是可编程线性霍尔传感器，可用于角度或者距离测量。主要参数是在非易失内存中进行编程的。HAL 817有比例输出特性。输出电压与磁通量和供电电压成比例。HAL 810提供脉宽调制输出。产品有带斩波偏置补偿的温度补偿霍尔片，交流直流转换器，为标定数据而设的冗余和锁定功能，以及各引脚的保护装置。数据信号处理，模拟偏置，温度飘移和机械应力都不会降低传感器的精确性。传感器、磁场和机械位置形成的偏差可以由客户／用户在最后装配时通过编程来补偿。这是对近来需要机械调整或者激光修正来标定的各种应用的低成本替代方案。HAL 810和HAL 817设计适用于恶劣环境下的汽车和工业应用，供电电压5伏，温度从−40 °C 到 170 °C注：HAL 817替代以前版本的HAL 805和HAL 815。封装是小尺寸含铅TO92UT。
