施邁賽接近開(kāi)關(guān)又稱(chēng)無(wú)觸點(diǎn)接近開(kāi)關(guān)，是理想的電子開(kāi)關(guān)量傳感器。當(dāng)金屬檢測(cè)體接近開(kāi)關(guān)的感應(yīng)區(qū)域，開(kāi)關(guān)就能無(wú)接觸，無(wú)壓力、無(wú)火花、迅速發(fā)出電氣指令，準(zhǔn)確反應(yīng)出運(yùn)動(dòng)機(jī)構(gòu)的位置和行程。

    SCHMERSAL接近開(kāi)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(kāi)關(guān)，當(dāng)物體接近開(kāi)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(kāi)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。

    振蕩振幅的減少由電子電路轉(zhuǎn)換成電信號(hào)，從而改變接近開(kāi)關(guān)的狀態(tài)。

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