ATS657传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

ATS657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ATS657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 ATS657 includes an optimized Hall-effect sensing integrated circuit (IC) and rare earth pellet to create a user friendly solution for direction detection and true zero-speed, digital gear tooth sensing in two-wire applications. The small package can be easily assembled and used in conjunction with a wide variety of gear tooth sensing applications.
