霍爾開(kāi)關(guān)是應(yīng)用霍爾效應(yīng)的半導(dǎo)體。一般用于電機(jī)中測(cè)定轉(zhuǎn)子轉(zhuǎn)速，如錄像機(jī)的磁鼓，電腦中的散熱風(fēng)扇等；是一種基于霍爾效應(yīng)的磁傳感器，已發(fā)展成一個(gè)品種多樣的磁傳感器產(chǎn)品族，并已得到普遍的應(yīng)用。 </p> <p> 霍爾開(kāi)關(guān)是一種基于霍爾效應(yīng)的器件，它可以見(jiàn)到到磁場(chǎng)的變化，這個(gè)特性使得它應(yīng)用普遍。我們以滑蓋手機(jī)為例，當(dāng)手機(jī)蓋側(cè)的磁鐵靠近手機(jī)側(cè)的霍爾開(kāi)關(guān)時(shí)，會(huì)產(chǎn)生霍爾電壓，然后進(jìn)行放大給手機(jī)的CUP處理，比如關(guān)閉屏幕等動(dòng)作。我司是專業(yè)的霍爾開(kāi)關(guān)生產(chǎn)廠家。
