線性霍爾開關(guān)的特點： </p> <p> 1、體積小、精確度高；2、靈敏度高、線性度好；3、溫度穩(wěn)定性好、可靠性高 </p> <p> 線性霍爾一些應(yīng)用領(lǐng)域： </p> <p> 1、電流傳感器；2、電源感應(yīng) 、磁（偏）傳感應(yīng)用、黑色金屬探測器、接近傳感器、液**置傳感器。 </p> <p> 線性霍爾電路注意事項；1 安裝時要盡量減少施加在電路外殼或引線上的機械應(yīng)力。；2 焊接溫度要低于260℃，時間小于5秒。；3若以N極從背面接近霍爾電路，輸出電壓減小，S極從背面接近，輸出增加；若從正面接近，輸出狀態(tài)與從背面接近正好相反。 </p><p> 霍爾元件可用多種半導(dǎo)體材料制作，如Ge、Si、InSb、GaAs、InAs、InAsP以及多層半導(dǎo)體異質(zhì)結(jié)構(gòu)量子阱材料等等。 </p> <p> 半導(dǎo)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(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。

我們都知道使用霍爾開關(guān)，必不可少要使用到磁鐵。因為霍爾傳感器是感應(yīng)磁場工作的。但是很多人不知道磁鐵的強度如何選擇？我們在選擇磁鐵的時候，一般磁場是要大于您所選擇霍爾工作點的1-2倍，這樣霍爾開關(guān)才會感應(yīng)到磁場并工作。 </p> <p> 在選擇霍爾開關(guān)的時候。每當(dāng)我們問起客戶的磁場是多大的時候，客戶都會說我的磁鐵是圓形的，或者說是比較小的，會去形容這個磁鐵的大小，外形。但是其實磁鐵的形狀和磁場的大小是沒有任何關(guān)系的，因為磁場的強度不會因為您磁鐵大就大，磁鐵小就小的。茂名全極霍爾開關(guān)</p><p
