雙極霍爾和全極霍爾目前是常用的霍爾開關(guān)，廣泛應(yīng)用于開關(guān)，測速，計量等應(yīng)用的產(chǎn)品上，但是實際應(yīng)用中很多人誤將雙極當成全極，或者全極當成雙極，造成在搭建霍爾電路或者設(shè)計電路時的困擾。如今我們就來詳細講下如何正確區(qū)分雙極霍爾開關(guān)和全極霍爾開關(guān)。1.雙極霍爾開關(guān)雙極霍爾一般都要指定一個磁極，同時需要兩個磁極分別控制高低電平，利用磁場NS極交替來輸出信號。如S極靠近時輸出低電平，N極靠近時輸出高電平。雙極霍爾典型應(yīng)用就是測速或者計數(shù)。如果磁場被移除，則是隨機輸出，有可能是打開，也有可能是關(guān)閉。雙極性霍爾開關(guān)特點：穩(wěn)定性好，江蘇全極霍爾開關(guān)，高靈敏度，寬電壓，一致性好，壽命長。2.全極霍爾開關(guān)全極性霍爾又叫無極性霍爾，其感應(yīng)方式為：全極霍爾不分南（S）北極(N)檢測磁場，磁鐵接近時輸出低電平，遠離時輸出高電平，全極霍爾的感應(yīng)方式與單極霍爾的感應(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。全極霍爾開關(guān)特點：低電壓，低功耗。

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>

霍爾開關(guān)是一種基于霍爾效應(yīng)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(yīng)用。 </p> <p> 霍爾器件具有許多優(yōu)點，它們的結(jié)構(gòu)牢固，體積小，重量輕，壽命長，安裝方便，功耗小，頻率高（可達1MHZ），耐震動，不怕灰塵、油污、水汽及鹽霧等的污染或腐蝕。 </p> <p> 霍爾線性器件的精度高、線性度好；霍爾開關(guān)器件無觸點、無磨損、輸出波形清晰、無抖動、無回跳、位置重復(fù)精度高（可達μm級）。取用了各種補償和保護措施的霍爾器件的工作溫度范圍寬，可達－55℃～150℃。 </p><p> 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。霍爾元件新春大促中~華芯質(zhì)量霍爾元件，多年行業(yè)好評，質(zhì)量好，價格優(yōu)，長期與多加**企業(yè)合作。</p><div
