A1642LK傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）規(guī)格書PDF中文資料

A1642LK屬于傳感器變送器的磁性傳感器-開關(guān)（固態(tài)）。由Allegro MicroSystems制造生產(chǎn)的A1642LK磁性傳感器 - 開關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)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(guān)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。

The A1642 is an optimized Hall effect sensing integrated circuit that provides a user-friendly solution for true zero-speed digital ring-magnet sensing in two-wire applications. This small package can be easily assembled and used in conjunction with a wide variety of target shapes and sizes.
