A3242LUA-T傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）規(guī)格書(shū)PDF中文資料

A3242LUA-T屬于傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）。由Allegro MicroSystems制造生產(chǎn)的A3242LUA-T磁性傳感器 - 開(kāi)關(guān)（固態(tài)）該系列產(chǎn)品使用固態(tài)技術(shù)來(lái)檢測(cè)是否存在超過(guò)某個(gè)特定幅度和/或標(biāo)示的磁場(chǎng)，并提供指示是否存在此類(lèi)磁場(chǎng)的雙態(tài)輸出。它們與磁簧開(kāi)關(guān)以及線性或羅盤(pán)型固態(tài)器件不同，前者通過(guò)使用移動(dòng)機(jī)械部件來(lái)提供類(lèi)似的功能，后者提供指示所施加磁場(chǎng)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.
