AK8778B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

AK8778B屬于傳感器變送器的磁性傳感器-開(kāi)關(guān)（固態(tài)）。由旭化成微電子株式會(huì)社制造生產(chǎn)的AK8778B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(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。

Overview

The AK8778B 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 AK8778B is for use in

the incremental pulse encoders or rotational detection systems.
