ATS667LSGTN-T屬于傳感器變送器的磁性傳感器-開關（固態(tài)）。由Allegro MicroSystems制造生產(chǎn)的ATS667LSGTN-T磁性傳感器 - 開關（固態(tài)）該系列產(chǎn)品使用固態(tài)技術來檢測是否存在超過某個特定幅度和/或標示的磁場，并提供指示是否存在此類磁場的雙態(tài)輸出。它們與磁簧開關以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機械部件來提供類似的功能，后者提供指示所施加磁場的強度和/或方向的可變輸出。

描述 Description

The ATS667 is a true zero-speed gear tooth sensor IC consisting of an optimized Hall IC-rare earth pellet configuration in a single overmolded package. The unique IC and package design provides a user-friendly solution for digital gear tooth sensing applications. This small package can be easily assembled and used in conjunction with gears of various shapes and sizes.
