因?yàn)?strong>SCHMERSAL位移傳感器可以根據(jù)不同的原理和不同的方法做成，而不同的位移傳感器對(duì)物體的“感知”方法也不同，所以常見的施邁賽接近開關(guān)有以下幾種：

    SCHMERSAL無源接近開關(guān)不需要電源，通過磁力感應(yīng)控制開關(guān)的閉合狀態(tài)。當(dāng)磁 或者鐵質(zhì)觸發(fā)器靠近開關(guān)磁場(chǎng)時(shí)，和開關(guān)內(nèi)部磁力作用控制閉合。特點(diǎn)：不需要電源，非接觸式，免維護(hù)，環(huán)保。

    德國(guó)施邁賽渦流式接近開關(guān)有時(shí)也叫電感式接近開關(guān)。它是利用導(dǎo)電物體在接近這個(gè)能產(chǎn)生電磁場(chǎng)接近開關(guān)時(shí)，使物體內(nèi)部產(chǎn)生渦流。這個(gè)渦流反作用到接近開關(guān)，使開關(guān)內(nèi)部電路參數(shù)發(fā)生變化，由此識(shí)別出有無導(dǎo)電物體移近，進(jìn)而控制開關(guān)的通或斷。這種接近開關(guān)所能檢測(cè)的物體必須是導(dǎo)電體。

    SCHMERSAL霍爾接近開關(guān)當(dāng)磁性物件移近霍爾開關(guān)時(shí)，開關(guān)檢測(cè)面上的霍爾元件因產(chǎn)生霍爾效應(yīng)而使開關(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)而控制開關(guān)的通或斷。這種接近開關(guān)的檢測(cè)對(duì)象必須是磁性物體。

    德國(guó)*SCHMERSAL光電式接近開關(guān)利用光電效應(yīng)做成的開關(guān)叫光電開關(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。

    上海維特銳直接從德國(guó)SCHMERSAL原廠家拿貨，直接供應(yīng)各種SCHMERSAL感應(yīng)傳感器，施邁賽磁性開關(guān)，施邁賽安全開關(guān)
