1.霍爾是敏感器件，在使用過程以及存儲過程中應注意采取靜電防護措施。 </p> <p> 2.適宜的電源電壓和負載電路及工作溫度是霍爾器件正常工作的先決條件，霍爾器件的供電電壓，負載電流及工作溫度不得超出規(guī)格書中多規(guī)定的范圍。 </p> <p> 3.所用工具，特別是焊接用的電烙鐵，必須嚴格接上地線，以保證電烙鐵不漏電，即電烙鐵的鐵皮是接地的，比較好選用低壓恒溫可調(diào)電烙鐵進行焊接。 </p> <p> 4.所有設備都應嚴格接地，并用檢電筆逐個查明確無漏電，才能開始工作。 </p> <p> 5.要求印制板及霍爾器件管腳嚴格經(jīng)過清潔處理，使它與焊錫有良好的浸潤性。華芯霍爾元件,多年數(shù)據(jù)驗證，北京單極霍爾開關，北京單極霍爾開關，北京單極霍爾開關,一致性高,無抖動,高精度,抗應力,可替代各大進口品牌,用16年數(shù)據(jù)說話,歡迎試樣.北京單極霍爾開關</p><div style="width:100%;text-align:

霍爾開關是應用霍爾效應的半導體。一般用于電機中測定轉(zhuǎn)子轉(zhuǎn)速，如錄像機的磁鼓，電腦中的散熱風扇等；是一種基于霍爾效應的磁傳感器，已發(fā)展成一個品種多樣的磁傳感器產(chǎn)品族，并已得到普遍的應用。 </p> <p> 霍爾開關是一種基于霍爾效應的器件，它可以見到到磁場的變化，這個特性使得它應用普遍。我們以滑蓋手機為例，當手機蓋側(cè)的磁鐵靠近手機側(cè)的霍爾開關時，會產(chǎn)生霍爾電壓，然后進行放大給手機的CUP處理，比如關閉屏幕等動作。我司是專業(yè)的霍爾開關生產(chǎn)廠家。河北單極霍爾開關霍爾哪家好,買霍爾元件還是選華芯晟!華芯晟提供各種類型的霍爾元件

霍爾開關的應用我司供應各種型號的霍爾開關。根據(jù)應用的不同可以分為開關型霍爾開關和線性霍爾開關。開關型霍爾開關又分為雙極鎖存型霍爾開關、全極霍爾開關、全極微功耗霍爾開關，單極霍爾開關。具體選型如下：雙極霍爾開關：檢測電機的轉(zhuǎn)速與位置、流量計、風扇電機、微型電機、無刷電機如HX41F、HXS41H、HX6571、HX6572等全極霍爾開關：數(shù)碼產(chǎn)品、水表、電表、燃氣表、電池供電的產(chǎn)品、智能水表、開關、手持設備如HX6383、HX6382、HX6393、HX6344等單極霍爾開關：電機、計數(shù)、轉(zhuǎn)速、開關、調(diào)檔位、擋車桿、接近開關、無刷電機、轉(zhuǎn)速檢測、流量傳感、無接觸式定位如HX6286、HX3144、HX6287、HX6287等線性霍爾開關：電流傳感器、踏板、轉(zhuǎn)把、速度調(diào)節(jié)、壓力傳感、磁場檢測如HX6689、HX6649、HX6659、HX6639、HX6669等。 </p><p> 如何判斷線性霍爾開關是否損壞？改變磁場的大小線性霍爾開關的好壞當霍爾開關通電，輸出端與電壓表連接時，當磁鐵從遠到近接近線性霍爾開關時，線性霍爾開關的輸出電壓逐漸由小變大。這表明線性霍爾開關是好的。如果磁鐵從遠到近逐漸接近線性霍爾開關，則線性霍爾開關的輸出電壓保持不變，表明線性霍爾開關具有相同的輸出電壓。線性霍爾開關已損壞。線性霍爾開關恒流源電流的改變來判斷線性霍爾開關的質(zhì)量當線性霍爾開關恒流源的電流由零逐漸變?yōu)轭~定電流（不能超過線性霍爾開關的額定電流），線性霍爾開關的輸出電壓由小逐漸變大，說明線性霍爾開關性能良好。如果線性霍爾開關的恒流從零逐漸變?yōu)轭~定電流，則線性霍爾開關的電壓保持不變，表明線性霍爾開關已損壞。華芯霍爾元件是質(zhì)量的霍爾元件生產(chǎn)廠家，廠家直銷，十七年專業(yè)做霍爾值得信賴！</p><div

霍爾元件可用多種半導體材料制作，如Ge、Si、InSb、GaAs、InAs、InAsP以及多層半導體異質(zhì)結(jié)構(gòu)量子阱材料等等。 </p> <p> 半導體中電子遷移率（電子定向運動的平均速度）比空穴遷移率高，因此N型半導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，應用非常普遍銻化銦元件由于在高溫時霍爾常數(shù)大，所以輸出較大，但對溫度**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，但價格較貴。不同材料適用于不同場合，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量指示儀表。
