A3242LUA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

A3242LUA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A3242LUA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(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。

Chopper-Stabilized Unipolar Hall-Effect Switches

The A3241 and A3242 integrated circuits are unipolar Hall-effect switches with digital outputs. These sensors are suited for operation over extended temperature ranges, up to +150°C. Superior high-temperature performance is made possible through an Allegro? patented dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
