A1244LUA-I2-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

A1244LUA-I2-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A1244LUA-I2-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 A1244 is a two-wire Hall-effect latch. The devices are produced on the Allegro™advanced BiCMOS wafer fabrication process, which implements a patented high frequency, 4-phase, chopper-stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.
