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。

    SCHMERSAL接近開關(guān)是一種無(wú)需與運(yùn)動(dòng)部件進(jìn)行機(jī)械直接接觸而可以作的位置開關(guān)，當(dāng)物體接近開關(guān)的感應(yīng)面到動(dòng)作距離時(shí)，不需要機(jī)械接觸及施加任何壓力即可使開關(guān)動(dòng)作，從而驅(qū)動(dòng)直流電器或給計(jì)算機(jī)（plc)裝置提供控制指令。

    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)
