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(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。如今我們就來詳細(xì)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(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NS極交替來輸出信號。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)用就是測速或者計(jì)數(shù)。如果磁場被移除，則是隨機(jī)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(diǎn)：穩(wěn)定性好，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(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(diǎn)：低電壓，低功耗。梅州線性霍爾開關(guān)價(jià)格質(zhì)量霍爾元件盡在華芯--十六年專業(yè)做霍爾華芯專業(yè)大量提供霍爾元件批發(fā),量大采購有優(yōu)惠!</p><div

霍爾的感應(yīng)距離也和磁場的強(qiáng)度有直接的關(guān)系，一般霍爾的感應(yīng)距離是在1CM左右。一般來說，要先選霍爾，選好霍爾之后再去配套磁鐵，這樣磁鐵和霍爾的配套性更強(qiáng)。要是需要感應(yīng)的距離比較遠(yuǎn)，那么就需要加大磁場，或選擇高靈敏度的霍爾開關(guān)。感應(yīng)距離的遠(yuǎn)近是需要磁場和霍爾共同搭配來使用的，也或者您的磁場特別強(qiáng)，可能靈敏度稍微低一些的霍爾開關(guān)也是可以感應(yīng)到的，當(dāng)然還是需要您在實(shí)際的電路中去測試的。

直流無刷電機(jī)具有節(jié)能、壽命長、穩(wěn)定性高等特點(diǎn)，廣泛應(yīng)用于空調(diào)、冰箱、汽車、電動汽車、工控等家電行業(yè)。直流無刷電動機(jī)的重要組成部分是霍爾開關(guān)，因?yàn)榛魻栭_關(guān)具有非接觸式、高安全性、高使用壽命和高穩(wěn)定性等優(yōu)點(diǎn)，能夠抵抗油污、粉塵等惡劣環(huán)境的影響。因此，霍爾開關(guān)是直流無刷電機(jī)的關(guān)鍵部件，其作用十分重要?；魻栭_關(guān)的選擇直接影響到直流無刷電機(jī)的質(zhì)量。一般使用鎖存型霍爾開關(guān)在無刷直流電機(jī)中，推薦使用HX41F/HXS41H/HX6571等鎖存型霍爾開關(guān)。華芯十七年專業(yè)做霍爾，提供多種類型的霍爾元件，歡迎咨詢選購。</p><div

造成霍爾開關(guān)失效的常見原因有哪些？我們在使用霍爾開關(guān)的過程中經(jīng)常會遇到霍爾工作了一段時(shí)間之后就停止工作的情況，這時(shí)，霍爾芯片可能是被損壞了，那是什么原因?qū)е碌哪?？可以從以下幾個(gè)方面來入手分析檢測：1.首先檢查外部電路，是否有虛焊漏焊的情況造成短路、斷路的現(xiàn)象。2.開關(guān)類的霍爾一般都需要外接一個(gè)上拉電阻才可以正常工作，檢查下電阻是否正常。3.單獨(dú)檢查下磁鐵，有些磁鐵存在時(shí)間過長使磁鐵消磁，導(dǎo)致霍爾感應(yīng)不到，無法正常工作。（注：霍爾與磁鐵之間有阻隔也會減弱磁場）4.是否超出了霍爾本身的溫度范圍，溫度過高會導(dǎo)致霍爾損壞，也會導(dǎo)致磁鐵消磁。5.檢查電壓、電流是否穩(wěn)定，是否在霍爾參數(shù)規(guī)定范圍內(nèi)，偏上限或下限會造成霍爾不穩(wěn)定，超出參數(shù)范圍會導(dǎo)致霍爾被瞬間擊穿造成損壞。佛山HX6649霍爾開關(guān)</p><p
