A3425LL傳感器變送器的磁性傳感器-開關（固態(tài)）規(guī)格書PDF中文資料

A3425LL屬于傳感器變送器的磁性傳感器-開關（固態(tài)）。由Allegro MicroSystems制造生產的A3425LL磁性傳感器 - 開關（固態(tài)）該系列產品使用固態(tài)技術來檢測是否存在超過某個特定幅度和/或標示的磁場，并提供指示是否存在此類磁場的雙態(tài)輸出。它們與磁簧開關以及線性或羅盤型固態(tài)器件不同，前者通過使用移動機械部件來提供類似的功能，后者提供指示所施加磁場的強度和/或方向的可變輸出。

Description

The A3425 is a dual–output-channel, bipolar switch with each channel comprising a separate complete Hall-effect sensor circuit with dedicated Hall element and separate digital output for speed and direction signal processing capability. The independent Hall elements (E1 integrated with OUTPUTA, and E2 integrated withOUTPUTB) are photolithographically aligned to better than 1 μm. Maintaining this accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch detection applications.
