德國(guó)施邁賽渦流式接近開(kāi)關(guān)有時(shí)也叫電感式接近開(kāi)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(kāi)關(guān)時(shí)，使物體內(nèi)部產(chǎn)生渦流。 施邁賽渦流反作用到接近開(kāi)關(guān)，使開(kāi)關(guān)內(nèi)部電路參數(shù)發(fā)生變化，由此識(shí)別出有無(wú)導(dǎo)電物體移近，進(jìn)而控制開(kāi)關(guān)的通或斷。這種接近開(kāi)關(guān)所能檢測(cè)的物體必須是導(dǎo)電體。 德國(guó)SCHMERSAL原裝接近開(kāi)關(guān)廣泛地應(yīng)用于機(jī)床、冶金、化工、輕紡和印刷等行業(yè)。在自動(dòng)控制系統(tǒng)中可作為限位、計(jì)數(shù)、定位控制和自動(dòng)保護(hù)環(huán)節(jié)等。 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(kāi)關(guān)，施邁賽安全開(kāi)關(guān)
