A1210LUA-T傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）規(guī)格書PDF中文資料

A1210LUA-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A1210LUA-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。

The Allegro?A1210-A1214 Hall-effect latches are next generation replacements for the popular Allegro 317x and 318x lines of latching switches. The A121x family, produced with BiCMOS technology, consists of devices that feature fast power-on time and low-noise operation. Device programming is performed after packaging, to ensure increased switchpoint accuracy by eliminating offsets that can be induced by package stress. Unique Hall element geometries and low-offset amplifiers help to minimize noise and to reduce the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
