AH1803传感器变送器的磁性传感器-开关（固态）规格书PDF中文资料

AH1803属于传感器变送器的磁性传感器-开关（固态）。由美台半导体制造生产的AH1803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。

General Description

AH1803 is with two Hall effect plates and a CMOS output driver, mainly designed for battery–operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). The total operation power is down to 24uW in the 3V supply.
