A3230LUA-T传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

A3230LUA-T属于传感器变送器的磁性传感器-开关（固态）。由Allegro MicroSystems制造生产的A3230LUA-T磁性传感器 - 开关（固态）该系列产品使用固态技术来检测是否存在超过某个特定幅度和/或标示的磁场，并提供指示是否存在此类磁场的双态输出。它们与磁簧开关以及线性或罗盘型固态器件不同，前者通过使用移动机械部件来提供类似的功能，后者提供指示所施加磁场的强度和/或方向的可变输出。

描述 Description

The A3230 Hall-effect sensor is a temperature stable, stress resistant bipolar switch. This sensor is the most sensitive Hall-effect device in the Allegro®bipolar switch family and is intended for ring-magnet sensing. Superior high-temperature performance is made possible through an Allegro patented dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device overmolding, temperature dependencies, and thermal

stress.
