雙極霍爾和全極霍爾目前是常用的霍爾開(kāi)關(guān)，廣泛應(yīng)用于開(kāi)關(guān)，汕頭HXS41H霍爾開(kāi)關(guān)，測(cè)速，計(jì)量等應(yīng)用的產(chǎn)品上，但是實(shí)際應(yīng)用中很多人誤將雙極當(dāng)成全極，或者全極當(dāng)成雙極，造成在搭建霍爾電路或者設(shè)計(jì)電路時(shí)的困擾。如今我們就來(lái)詳細(xì)講下如何正確區(qū)分雙極霍爾開(kāi)關(guān)和全極霍爾開(kāi)關(guān)。1.雙極霍爾開(kāi)關(guān)雙極霍爾一般都要指定一個(gè)磁極，同時(shí)需要兩個(gè)磁極分別控制高低電平，利用磁場(chǎng)NS極交替來(lái)輸出信號(hào)。如S極靠近時(shí)輸出低電平，N極靠近時(shí)輸出高電平。雙極霍爾典型應(yīng)用就是測(cè)速或者計(jì)數(shù)。如果磁場(chǎng)被移除，則是隨機(jī)輸出，有可能是打開(kāi)，也有可能是關(guān)閉。雙極性霍爾開(kāi)關(guān)特點(diǎn)：穩(wěn)定性好，高靈敏度，汕頭HXS41H霍爾開(kāi)關(guān)，寬電壓，一致性好，壽命長(zhǎng)。2.全極霍爾開(kāi)關(guān)全極性霍爾又叫無(wú)極性霍爾，其感應(yīng)方式為：全極霍爾不分南（S）北極(N)檢測(cè)磁場(chǎng)，磁鐵接近時(shí)輸出低電平，遠(yuǎn)離時(shí)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(kāi)關(guān)會(huì)指定磁極，而全極性霍爾開(kāi)關(guān)不會(huì)指定磁極，汕頭HXS41H霍爾開(kāi)關(guān)，任何磁極靠近輸出低電平信號(hào)，離開(kāi)輸出高電平信號(hào)。全極霍爾開(kāi)關(guān)特點(diǎn)：低電壓，低功耗。華芯霍爾元件，專業(yè)霍爾開(kāi)關(guān)廠家，值得信賴。汕頭HXS41H霍爾開(kāi)關(guān)</p><div

半導(dǎo)體中電子遷移率（電子定向運(yùn)動(dòng)的平均速度）比空穴遷移率高，因此N型半導(dǎo)體較適合于制造靈敏度高的霍爾元件霍爾元件。 </p> <p> 常用的半導(dǎo)體材料N型硅、N型鍺、銻化銦、砷化銦和不同比例亞砷酸銦和磷酸銦組成的In型固溶體等。 </p> <p> 其中N型鍺容易加工，其霍爾常數(shù)、溫度性能、輸出線性都較好，應(yīng)用非常普遍銻化銦元件由于在高溫時(shí)霍爾常數(shù)大，所以輸出較大，但對(duì)溫度**敏感，尤其在低溫范圍內(nèi)溫度系數(shù)大；砷化銦的霍爾常數(shù)較小，溫度系數(shù)也較小，輸出線性好；砷化鎵的溫度特性和輸出線性好，是較理想的材料，但價(jià)格較貴。不同材料適用于不同場(chǎng)合，銻化銦適用于作為敏感元件，鍺和砷化銦霍爾元件適用于測(cè)量指示儀表。

線性霍爾和開(kāi)關(guān)式霍爾可以通用嗎？在轉(zhuǎn)把上用的霍爾開(kāi)關(guān)，我們把它叫線性霍爾開(kāi)關(guān)。就是說(shuō)，根據(jù)磁場(chǎng)感應(yīng)的大小，它的電壓會(huì)隨著磁場(chǎng)大小的變化而變化，磁場(chǎng)感應(yīng)的強(qiáng)度越強(qiáng)，翰出的霍爾電壓就越大；磁場(chǎng)感應(yīng)的強(qiáng)度越小，翰出的電壓就越小。所以我們?cè)谵D(zhuǎn)動(dòng)轉(zhuǎn)把時(shí)，電壓可以從由小到大，逐漸加大，或者是逐漸變小。在電機(jī)上用的霍爾開(kāi)關(guān)，我們把它叫做開(kāi)關(guān)式霍爾開(kāi)關(guān)。在磁場(chǎng)靠近霍爾開(kāi)關(guān)時(shí)，這是霍爾元件直接導(dǎo)通狀態(tài)，輸出比較大電壓。磁場(chǎng)感應(yīng)離開(kāi)時(shí)，直接進(jìn)入關(guān)閉狀態(tài)，沒(méi)有電壓輸出。就像個(gè)開(kāi)關(guān)一樣的，保持通斷的功能。不能像轉(zhuǎn)把霍爾開(kāi)關(guān)那樣，逐步的施加電壓。所以這兩種霍爾開(kāi)關(guān)，因?yàn)榉诺奈恢貌煌?，所涉及的原理也不太一樣，所以它們是不能互相代?</p><p> 霍爾開(kāi)關(guān)在電子防盜鎖中的應(yīng)用 </p> <p> 電子防盜鎖主要由電池供電，內(nèi)部裝置對(duì)功耗有一定要求。全級(jí)霍爾開(kāi)關(guān)非常低的工作電壓達(dá)到2.4V，全級(jí)霍爾開(kāi)關(guān)的功耗達(dá)到微安級(jí)，經(jīng)常被應(yīng)用于低功耗產(chǎn)品中。 </p> <p> 微功率霍爾開(kāi)關(guān)主要在電子鎖中起到限位開(kāi)關(guān)的作用，起到霍爾開(kāi)關(guān)與磁鐵的協(xié)調(diào)作用。磁鐵靠近霍爾開(kāi)關(guān)的時(shí)候低電平輸出。當(dāng)磁鐵離開(kāi)霍爾開(kāi)關(guān)元素輸出一個(gè)高水平并進(jìn)行關(guān)閉動(dòng)作時(shí)，做一個(gè)打開(kāi)動(dòng)作。 </p> <p> 這種全級(jí)低功耗的霍爾開(kāi)關(guān)可以感知N級(jí)和S級(jí)，無(wú)論即將到來(lái)的N或S電平是信號(hào)輸出，然后進(jìn)行動(dòng)作。它是一種基于混合信號(hào)CMOS技術(shù)的非極性霍爾開(kāi)關(guān)。該芯片采用先進(jìn)的斬波穩(wěn)定技術(shù)，能夠提供準(zhǔn)確、穩(wěn)定的磁開(kāi)關(guān)點(diǎn)。如HX6383,HX6363,HX6393,HX6373等都是全極微功耗霍爾開(kāi)關(guān)

行車記錄儀是一種記錄車輛在行駛過(guò)程中的圖像和聲音的儀器。行車記錄儀安裝好后，可以記錄車輛行駛?cè)^(guò)程的視頻圖像和聲音，為交通意外提供充分的證據(jù)。 </p> <p> 行車記錄儀霍爾傳感器主要起行車記錄儀的速度檢測(cè)功能。行車記錄儀霍爾傳感器一般采用全極霍爾傳感器。交通記錄儀霍爾傳感器的應(yīng)用范圍很廣，不同類型的溫度會(huì)有所不同。行車記錄儀的霍爾傳感器也會(huì)有所不同，類型選擇也比較普遍。一般使用全極微功耗的霍爾元件，如如HX6383，HX6382,HX6363,HX6373等霍爾元件,十六年專業(yè)品質(zhì),歡迎大量采購(gòu)!***霍爾供應(yīng)商華芯晟,大廠供貨,量大無(wú)憂,歡迎大量采購(gòu)!茂名HX6573霍爾開(kāi)關(guān)廠家</p><p

其次，霍爾開(kāi)關(guān)在電動(dòng)汽車電機(jī)中的作用：霍爾開(kāi)關(guān)在電動(dòng)汽車電機(jī)中的主要作用是改變相電流的方向，用來(lái)代替電機(jī)的電刷，所以使用霍爾開(kāi)關(guān)的電機(jī)必須是無(wú)刷電機(jī)。一般使用鎖存型霍爾開(kāi)關(guān)如HX41F,HXS41H,HX6571等 </p>

霍爾開(kāi)關(guān)在電動(dòng)車輛斷開(kāi)制動(dòng)中的作用：斷開(kāi)制動(dòng)的霍爾開(kāi)關(guān)是將制動(dòng)時(shí)產(chǎn)生的磁場(chǎng)強(qiáng)度變化轉(zhuǎn)化為數(shù)字電壓，為電機(jī)提供動(dòng)力啟動(dòng)剎車裝置。一般使用單極霍爾開(kāi)關(guān)如HX6286,HX6278,HX6287等。汕頭HXS41H霍爾開(kāi)關(guān)</p><p
