PS-05P2接近開(kāi)關(guān)IFL8-18-10YG

1.原理：由電感線(xiàn)圈和電容及晶體管組成振蕩器，并產(chǎn)生一個(gè)交變磁場(chǎng)，當(dāng)有金屬物體接近這一磁場(chǎng)時(shí)就會(huì)在金屬物體內(nèi)產(chǎn)生渦流，從而導(dǎo)致振蕩停止，這種變化被后極放大處理后轉(zhuǎn)換成晶體管開(kāi)關(guān)信號(hào)輸出。

2.特點(diǎn)：A、抗干擾性能好，開(kāi)關(guān)頻率高，大于200HZ. B、只能感應(yīng)金屬

3.應(yīng)用在各種機(jī)械設(shè)備上作位置檢測(cè)、計(jì)數(shù)信號(hào)拾取等。

這種開(kāi)關(guān)的測(cè)量通常是構(gòu)成電容器的一個(gè)極板，而另一個(gè)極板是開(kāi)關(guān)的外殼。這個(gè)外殼在測(cè)量過(guò)程中通常是接地或與設(shè)備的機(jī)殼相連接。當(dāng)有物體移向接近開(kāi)關(guān)時(shí)，不論它是否為導(dǎo)體，由于它的接近，總要使電容的介電常數(shù)發(fā)生變化，從而使電容量發(fā)生變化，使得和測(cè)量頭相連的電路狀態(tài)也隨之發(fā)生變化，由此便可控制開(kāi)關(guān)的接通或斷開(kāi)。這種接近開(kāi)關(guān)檢測(cè)的對(duì)象，不限于導(dǎo)體，可以絕緣的液體或粉狀物等。

霍爾接近開(kāi)關(guān)：霍爾元件是一種磁敏元件。利用霍爾元件做成的開(kāi)關(guān)，叫做霍爾開(kāi)關(guān)。當(dāng)磁性物件移近霍爾開(kāi)關(guān)時(shí)，開(kāi)關(guān)檢測(cè)面上的霍爾元件因產(chǎn)生霍爾效應(yīng)而使開(kāi)關(guān)內(nèi)部電路狀態(tài)發(fā)生變化，由此識(shí)別附近有磁性物體存在，進(jìn)而控制開(kāi)關(guān)的通或斷。這種接近開(kāi)關(guān)的檢測(cè)對(duì)象必須是磁性物體。

光電式接近開(kāi)關(guān)：利用光電效應(yīng)做成的開(kāi)關(guān)叫光電開(kāi)關(guān)。將發(fā)光器件與光電器件按一定方向裝在同一個(gè)檢測(cè)頭內(nèi)。當(dāng)有反光面（被檢測(cè)物體）接近時(shí)，光電器件接收到反射光后便在信號(hào)輸出，由此便可“感知"有物體接近。
