因為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物體的“感知”方法也不同 德國施邁賽渦流式接近開關(guān)有時也叫電感式接近開關(guān)。它是利用導(dǎo)電物體在接近這個能產(chǎn)生電磁場接近開關(guān)時，使物體內(nèi)部產(chǎn)生渦流。這個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，由此識別出有無導(dǎo)電物體移近，進而控制開關(guān)的通或斷。這種接近開關(guān)所能檢測的物體必須是導(dǎo)電體。 上海維特銳直接從德國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) SRB-NA-R-C.26-230VAC SRB-NA-R-C26-230VAC SRB-NA-NF-24V SRB-NA-NF-12VDC SRB-NA-R-C.38-24V SRB-NA-R-C38-24V SRB-NA-R-C.21-24V SRB-NA-R-C21-24V SRB-NA-R-C.19-24VDC SRB-NA-R-C19-24VDC SRB-NA-R-C19-24VAC SRB-NA-R-C.19-24VAC SRB-NA-R-C.27-24V SRB-NA-R-C27-24V SRB-NA-R-C.22-24V SRB-NA-R-C22-24V SRB-NA-R-C.20-24V SRB-NA-R-C20-24V SRB-NA-R-C.35/WE-24V SRB-NA-R-C35/WE-24V
