造成霍爾開關失效的常見原因有哪些？我們在使用霍爾開關的過程中經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，那是什么原因導致的呢？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、斷路的現象。2.開關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，導致霍爾感應不到，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，溫度過高會導致霍爾損壞，也會導致磁鐵消磁。5.檢查電壓，東莞HX41F-N霍爾開關價格、電流是否穩(wěn)定，是否在霍爾參數規(guī)定范圍內，偏上限或下限會造成霍爾不穩(wěn)定，超出參數范圍會導致霍爾被瞬間擊穿造成損壞，東莞HX41F-N霍爾開關價格。華芯16年專業(yè)做線性霍爾元件量大從優(yōu)!霍爾元件抗應力,無抖動，東莞HX41F-N霍爾開關價格,一致性好,可替代進口產品。東莞HX41F-N霍爾開關價格</p><div

霍爾元件應用霍爾效應的半導體。所謂霍爾效應，是指磁場作用于載流金屬導體、半導體中的載流子時，產生橫向電位差的物理現象。金屬的霍爾效應是1879年被美國物理學家霍爾發(fā)現的。當電流通過金屬箔片時，若在垂直于電流的方向施加磁場，則金屬箔片兩側面會出現橫向電位差。半導體中的霍爾效應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。利用霍爾效應可以設計制成多種傳感器?；魻栯娢徊頤H的基本關系為：式中 RH――霍爾系數；n――單位體積內載流子或自由電子的個數；q――電子電量；I――通過的電流；B――垂直于I的磁感應強度；d――導體的厚度。對于半導體和鐵磁金屬，霍爾系數表達式和式（2）不同。由于通電導線周圍存在磁場，其大小和導線中的電流成正比，故可以利用霍爾元件測量出磁場，就可確定導線電流的大小。利用這一原理可以設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，則在該元件中將產生電流I，元件上同時產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。河南HXS41H霍爾開關價格華芯多年專業(yè)做霍爾,大品牌值得信賴,精選各類霍爾元件,好評如潮,庫存充足!霍爾元件一站搞定,價格優(yōu)惠!</p><div

在外加磁場和霍爾激勵電流為I的情況下，在輸出端空載測得的霍爾電勢差稱為霍爾輸出電壓。 </p> <p> 10、霍爾電壓輸出比率 </p> <p> 霍爾不等位電勢與霍爾輸出電勢的比率。 </p> <p> 11、霍爾寄生直流電勢 </p> <p> 在外加磁場為零、霍爾元件用交流激勵時，霍爾電極輸出除了交流不等位電勢外，還有一直流電勢，稱寄生直流電勢。 </p> <p> 12、霍爾不等位電勢 </p> <p> 在沒有外加磁場和霍爾激勵電流為I的情況下，環(huán)境溫度每變化1℃時，不等位電勢的相對變化率。 </p> <p> 13、霍爾電勢溫度系數 </p> <p> 在外加磁場和霍爾激勵電流為I的情況下，環(huán)境溫度每變化1℃時，不等位電勢的相對變化率。它同時也是霍爾系數的溫度系數。 </p> <p> 14、熱阻Rth </p> <p> 霍爾元件工作時功耗每增加1W，霍爾元件升高的溫度值稱為它的熱阻，它反映了元件散熱的難易程度。東莞HX41F-N霍爾開關價格</p><p>
