單極性霍爾開關的感應方式：磁場的一個磁極靠近它，輸出低電位電壓（低電平）或關的信號，磁場磁極離開它輸出高電位電壓（高電平）或開的信號，但要注意的是，單極性霍爾開關它會指定某磁極感應才有效，一般是正面感應磁場S極，反面感應N極。 </p> <p> 雙極性霍爾開關的感應方式：因為磁場有兩個磁極N、S（正磁或負磁），所以兩個磁極分別控制雙極性霍爾開關的開和關（高低電平），它一般具有鎖定的作用，也就是說當磁極離開后，霍爾輸出信號不發(fā)生改變，直到另一個磁極感應。另外，雙極性霍爾開關的初始狀態(tài)是隨機輸出，有可能是高電平，也有可能是低電平。 </p> <p> 全極性霍爾開關的感應方式：全極性霍爾開關的感應方式與單極性霍爾開關的感應方式相似，區(qū)別在于，單極性霍爾開關會指定磁極，而全極性霍爾開關不會指定磁極，任何磁極靠近輸出低電平信號，離開輸出高電平信號。 </p><p> 霍爾元件是一種基于霍爾效應的磁傳感器，已發(fā)展成一個品種多樣的磁傳感器產(chǎn)品族，并已得到普遍的應用。 </p> <p>

霍爾元件電子剎把改為機械剎把：機械剎把兩根線中的一根與信號線連接，另一根與負極線連接。不使用紅色5伏。其原理是機械剎把將兩根導線連接到控制器內(nèi)部三極管的集電極和負極（以常用的NPN電子開關電路為例）。集電極上是控制器速度信號通過的地方，即一旦機械剎把開關閉合，速度信號被旁路到地面（負極）。低電平：剎車線控制器對外輸出電壓信號路過剎把開關，關閉后信號倒地，剎車動作。高電平：將電壓信號輸入控制器的剎把線，打開控制器中的電子開關，剎車動作。深圳庫存霍爾元件哪家好</p><p
