A1158LUA-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

A1158LUA-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A1158LUA-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。

Description

The A1150, A1152, A1153, A1155, A1156, A1157, and A1158 comprise a family of two-wire, unipolar, Hall-effect switches, which are factory-trimmed to optimize magnetic switchpoint accuracy. These devices are produced on the Allegro? advanced BiCMOS wafer fabrication process, which implements a patented high frequency, 4-phase, chopper-stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.
