AK8778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

AK8778屬于傳感器變送器的磁性傳感器-開關（固態(tài)）。由旭化成微電子株式會社制造生產(chǎn)的AK8778磁性傳感器 - 開關（固態(tài)）該系列產(chǎn)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。

Overview

The AK8778 is a Hall effect latch which detects both “vertical magnetic field” and “horizontal magnetic field” (perpendicular and parallel to the marking side of the package) at the same time. The pulse output F and direction output D are switched according to the vertical and horizontal magnetic fields applied to the device. The direction is calculated internally and output D is switched at a rising or falling edge of output F. The AK8778 is for use in the incremental pulse encoders or rotational detection systems.
