霍爾開關(guān)器件按照霍爾開關(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)，深圳全極霍爾開關(guān)價格。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。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(fù)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(dāng)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(yīng)。另外，雙極性霍爾開關(guān)的初始狀態(tài)是隨機(jī)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，深圳全極霍爾開關(guān)價格，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。我公司霍爾產(chǎn)品擁有超大庫存，深圳全極霍爾開關(guān)價格，可以快速發(fā)貨。每一箱霍爾產(chǎn)品都會在工廠備案，提供一對一完善的售后服務(wù)。深圳全極霍爾開關(guān)價格</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間之后就停止工作的情況，這時，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上拉電阻才可以正常工作，檢查下電阻是否正常。3.單獨檢查下磁鐵，有些磁鐵存在時間過長使磁鐵消磁，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。 </p><p> 霍爾開關(guān)的檢測方法 </p> <p> 如何檢測霍爾元件有沒有發(fā)生損壞呢？取三孔插座一個,1腳為5-15V電源,2腳接地,3腳接輸出。把霍爾開關(guān)按1,2,3腳插 </p> <p> 接在插座上。接通電源，萬用表接3,2腳測輸出電壓。用磁鐵一磁極靠近霍爾開關(guān)的正面，觀察萬用表輸出電壓，換用另一磁極靠近霍爾的正面，觀察萬用表輸出電壓。磁極靠近霍爾開關(guān)時，若輸出電壓出現(xiàn)跳變，霍爾開關(guān)屬于正常。若電壓不變，萬用表改接1,3腳，重復(fù)上述過程，若輸出電壓仍不變，說明霍爾開關(guān)損壞。華芯霍爾元件，專業(yè)霍爾開關(guān)廠家，值得信賴。</p><div

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(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)計電路時的困擾。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(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：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，磁鐵接近時輸出低電平，遠(yuǎn)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。深圳全極霍爾開關(guān)價格</p><p>
