接近開關(guān)按供電方式可分為；直流型和交流型，按輸出型式又可分為直流兩線制、直流三線制、直流四線制、交流兩線制和交流三線制。
1兩線制接近開關(guān)
兩線制接近開關(guān)安裝簡單，接線方便；應(yīng)用比較廣泛，但卻有殘余電壓和漏電流大的缺點。
2直流三線式
直流三線式接近開關(guān)的輸出型有NPN和PNP兩種，70年代日本產(chǎn)品絕大多數(shù)是NPN輸出，西歐各國NPN、PNP兩種輸出型都有。PNP輸出接近開關(guān)一般應(yīng)用在PLC或計算機作為控制指令較多，NPN輸出接近開關(guān)用于控制直流繼電器較多，在實際應(yīng)用中要根據(jù)控制電路的特性進行選擇其輸出形式。 方形電感式接近開關(guān)SQS19-Z4N接近開關(guān)現(xiàn)貨供應(yīng)方形電感式接近開關(guān)SQS19-Z4N接近開關(guān)現(xiàn)貨供應(yīng)方形電感式接近開關(guān)SQS19-Z4N接近開關(guān)現(xiàn)貨供應(yīng)方形電感式接近開關(guān)SQS19-Z4N接近開關(guān)現(xiàn)貨供應(yīng)方形電感式接近開關(guān)SQS19-Z4N接近開關(guān)現(xiàn)貨供應(yīng)
