按照霍爾開關(guān)的感應(yīng)方式可將它們分為：單極性霍爾開關(guān)、雙極性霍爾開關(guān)、全極性霍爾開關(guān)。 </p> <p> 單極性霍爾開關(guān)的感應(yīng)方式：磁場的一個磁極靠近它，輸出低電位電壓（低電平）或關(guān)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(guān)它會指定某磁極感應(yīng)才有效，一般是正面感應(yīng)磁場S極，反面感應(yīng)N極。 </p> <p> 雙極性霍爾開關(guān)的感應(yīng)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(guān)的開和關(guān)（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，無錫HX6373霍爾開關(guān)價格，直到另一個磁極感應(yīng)。另外，雙極性霍爾開關(guān)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。全極性霍爾開關(guān)的感應(yīng)方式：全極性霍爾開關(guān)的感應(yīng)方式與單極性霍爾開關(guān)的感應(yīng)方式相似，區(qū)別在于，單極性霍爾開關(guān)會指定磁極，而全極性霍爾開關(guān)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。霍爾元件,華芯多年專業(yè)做霍爾,大品牌值得信賴,精選各類霍爾元件，無錫HX6373霍爾開關(guān)價格,好評如潮，無錫HX6373霍爾開關(guān)價格,庫存充足!霍爾元件一站搞定。無錫HX6373霍爾開關(guān)價格</p><div

霍爾元件應(yīng)用霍爾效應(yīng)的半導(dǎo)體。所謂霍爾效應(yīng)，是指磁場作用于載流金屬導(dǎo)體、半導(dǎo)體中的載流子時，產(chǎn)生橫向電位差的物理現(xiàn)象。金屬的霍爾效應(yīng)是1879年被美國物理學(xué)家霍爾發(fā)現(xiàn)的。當電流通過金屬箔片時，若在垂直于電流的方向施加磁場，則金屬箔片兩側(cè)面會出現(xiàn)橫向電位差。半導(dǎo)體中的霍爾效應(yīng)比金屬箔片中更為明顯，而鐵磁金屬在居里溫度以下將呈極強的霍爾效應(yīng)。利用霍爾效應(yīng)可以設(shè)計制成多種傳感器?；魻栯娢徊頤H的基本關(guān)系為：式中 RH――霍爾系數(shù)；n――單位體積內(nèi)載流子或自由電子的個數(shù)；q――電子電量；I――通過的電流；B――垂直于I的磁感應(yīng)強度；d――導(dǎo)體的厚度。對于半導(dǎo)體和鐵磁金屬，霍爾系數(shù)表達式和式（2）不同。由于通電導(dǎo)線周圍存在磁場，其大小和導(dǎo)線中的電流成正比，故可以利用霍爾元件測量出磁場，就可確定導(dǎo)線電流的大小。利用這一原理可以設(shè)計制成霍爾電流傳感器。若把霍爾元件置于電場強度為E、磁場強度為H的電磁場中，則在該元件中將產(chǎn)生電流I，元件上同時產(chǎn)生的霍爾電位差和電場強度E成正比，如果再測出該電磁場的磁場強度，則電磁場的功率密度瞬時值P可由確定。中山HX6689霍爾開關(guān)價格華芯十六年專業(yè)做霍爾元件,量大從優(yōu)!為客戶提供質(zhì)量的產(chǎn)品,專業(yè)的技術(shù)支持及完善的服務(wù)!</p><div

1）將霍爾開關(guān)類比成一個普通的電器按鍵開關(guān)。2）當無磁場時（或磁感應(yīng)強度小于一定值），霍爾開關(guān)是關(guān)閉狀態(tài)（假定磁感應(yīng)強度小于一定值，霍爾開關(guān)是對應(yīng)關(guān)閉狀態(tài)），類似手動把電器的開關(guān)關(guān)閉，電器不工作。當有磁場時（或磁感應(yīng)強度大于一定值），霍爾開關(guān)是導(dǎo)通狀態(tài)（假定磁感應(yīng)強度大于一定值，霍爾開關(guān)是對應(yīng)導(dǎo)通狀態(tài)），類似手動把電器的開關(guān)打開，電器正常工作。 </p><p> 霍爾線性器件 </p> <p> 線性霍爾元件是一種模擬信號輸出的磁傳感器，輸出電壓隨輸入的磁力密度線性變化。 </p> <p> 線性霍爾效應(yīng)傳感器 IC 的電壓輸出會精確追尋磁通密度的變化。在靜態(tài)（無磁場）時，從理論上講，輸出應(yīng)等于在工作電壓及工作溫度范圍內(nèi)的電源電壓的一半。增加南極磁場將增加來自其靜態(tài)電壓的電壓。相反，增加北極磁場將增加來自其靜態(tài)電壓的電壓。這些部件可測量電流的角、接近性、運動及磁通量。它們能夠以磁力驅(qū)動的方式反映機械事件。 </p> <p> 線性霍爾器件廣泛應(yīng)用需要模擬量輸出的應(yīng)用環(huán)境。如：汽車油門踏板，電動車油門，游戲手柄，液位計等等。霍爾元件哪家好？無錫華芯霍爾元件是專業(yè)的霍爾元件生產(chǎn)廠家，提供市面上的霍爾元件選型配型。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
