接近開關(guān)，是非常常見的檢測元件。它可以檢測物體的有無，根據(jù)被檢測物體，可以分為容性接近開關(guān)和感性接近開關(guān)兩種。其中，容性接近開關(guān)用于檢測非金屬，感性接近開關(guān)用于檢測金屬（主要是鐵）。接近開關(guān)，輸出的是數(shù)字量信號，江西光電接近開關(guān)規(guī)格，因此，對于PLC來說，接近開關(guān)就是輸入信號。常用的接近開關(guān)有三根線分別為，棕色，藍(lán)色，黑色。其中，棕色接24V，藍(lán)色接0V，是給接近開關(guān)供電的，黑色是接近開關(guān)的輸出，接到PLC上。如上圖所示，這就是接近開關(guān)的接線！！不光接近開關(guān)，光電開關(guān)，各種光纖開關(guān)，都采用這種接法。而棕藍(lán)黑三色已經(jīng)成為了國際標(biāo)準(zhǔn)。根據(jù)輸出極性，接近開關(guān)分為NPN和PNP兩種，因此，NPN輸出的接近開關(guān)，江西光電接近開關(guān)規(guī)格，只能接到采用NPN接法的PLC上，江西光電接近開關(guān)規(guī)格，如果接到PNP接法的PLC上，PLC是接受不到來自接近開關(guān)的信號的。南通光電接近開關(guān)質(zhì)量哪家好，歡迎來電咨詢，無錫日環(huán)傳感科技有限公司。江西光電接近開關(guān)規(guī)格</p><div

這種現(xiàn)象就稱為霍爾效應(yīng)。兩端具有的電位差值稱為霍爾電勢U，其表達(dá)式為U=K·I·B/d其中K為霍爾系數(shù)，I為薄片中通過的電流，B為外加磁場（洛倫慈力Lorrentz）的磁感應(yīng)強(qiáng)度，d是薄片的厚度。由此可見，霍爾效應(yīng)的靈敏度高低與外加磁場的磁感應(yīng)強(qiáng)度成正比的關(guān)系。我門銷售的霍爾開關(guān)就屬于這種有源磁電轉(zhuǎn)換器件，它是在霍爾效應(yīng)原理的基礎(chǔ)上，利用集成封裝和組裝工藝制作而成，它可方便的把磁輸入信號轉(zhuǎn)換成實(shí)際應(yīng)用中的電信號，同時(shí)又具備工業(yè)場合實(shí)際應(yīng)用易操作和可靠性的要求。霍爾開關(guān)的輸入端是以磁感應(yīng)強(qiáng)度B來表征的，當(dāng)B值達(dá)到一定的程度（如B1）時(shí)，霍爾開關(guān)內(nèi)部的觸發(fā)器翻轉(zhuǎn)，霍爾開關(guān)的輸出電平狀態(tài)也隨之翻轉(zhuǎn)。輸出端一般采用晶體管輸出，和接近開關(guān)類似有NPN、PNP、常開型、常閉型、鎖存型（雙極性）、雙信號輸出之分?；魻栭_關(guān)具有無觸電、低功耗、長使用壽命、響應(yīng)頻率高等特點(diǎn)，內(nèi)部采用環(huán)氧樹脂封灌成一體化，所以能在各類惡劣環(huán)境下可靠的工作?；魻栭_關(guān)可應(yīng)用于接近開關(guān)，壓力開關(guān)，里程表等，作為一種新型的電器配件。霍爾開關(guān)的功能類似干簧管磁控開關(guān)，但是比它壽命長，響應(yīng)快無磨損，而且安裝時(shí)要注意磁鐵的極性，磁鐵極性裝反無法工作。湖州環(huán)形接近開關(guān)用途宿遷接近開關(guān)質(zhì)量哪家好，歡迎來電咨詢，無錫日環(huán)傳感科技有限公司。</p><div

SQ）二、接近開關(guān)的分類和工作原理按照工作原理的不同可以分為電感式、電容式、光電式和磁感式等。如果按照電路電流的類型又可以分為交流型和直流型。1、電感式接近開關(guān)電感式接近開關(guān)電感式接近開關(guān)的感應(yīng)頭是一個(gè)具有鐵氧體磁芯的電感線圈，只能檢測金屬體。振蕩器在感應(yīng)頭表面產(chǎn)生一個(gè)交變磁場，當(dāng)金屬物體接近感應(yīng)頭時(shí)，接近開關(guān)內(nèi)部動(dòng)作，從而達(dá)到“開”和“關(guān)”的控制。2、電容式接近開關(guān)電容式接近開關(guān)電容式接近開關(guān)的感應(yīng)頭是一個(gè)圓形或者方形平板電極，與振蕩電路的地線形成一個(gè)分布電容，當(dāng)有導(dǎo)體或其他介質(zhì)接近感應(yīng)頭時(shí)，電容量增大而使振蕩器停止振蕩，經(jīng)過整形放大器輸出電信號。電容式接近開關(guān)可以檢查金屬、非金屬和液體。3、磁感式接近開關(guān)磁感式接近開關(guān)（霍爾接近開關(guān)）磁感式接近開關(guān)主要是指霍爾接近開關(guān)，其工作原理是霍爾效應(yīng)，當(dāng)磁性物體接近霍爾開關(guān)時(shí)，霍爾接近開關(guān)的狀態(tài)改變，比如從“開”變?yōu)椤瓣P(guān)”。4、光電式接近開關(guān)光電式接近開關(guān)利用光電效應(yīng)制成的傳感器稱為光電式傳感器。光電式傳感器是根據(jù)投光器發(fā)出的光，在檢測體上發(fā)生光亮增減，用光電變換元件組成的受光器檢測物體的有無、大小的非接觸式的控制器件。金華接近開關(guān)質(zhì)量哪家好，歡迎來電咨詢，無錫日環(huán)傳感科技有限公司。</p><div
