A17201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

A17201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A17201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(gè)特定幅度和/或標(biāo)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(dòng)機(jī)械部件來提供類似的功能，后者提供指示所施加磁場的強(qiáng)度和/或方向的可變輸出。

DESCRIPTION

The A17201 is an AC-coupled Hall-effect sensor IC which includes monolithic integrated circuits that switch in response to changing differential magnetic fields created by rotating ring magnets or, when coupled with a magnet, by ferrous targets. This device also includes an integrated tracking capacitor that provides the high accuracy of analog sensing without an external filter capacitor. This reduces cost and components, while improving the reliability of the final sensor solution.
