日本小金井電磁閥EA10F1-21-25-75-PS3原裝現貨
在氣路（或液路）上來說，兩位三通日本小金井電磁閥具有1個進氣孔（接進氣氣源）、1個出氣孔（提供給目標設備氣源）、1個排氣孔（一般安裝一個消聲器，如果不怕噪音的話也可以不裝。 兩位五通電磁閥具有1個進氣孔（接進氣氣源）、1個正動作出氣孔和1個反動作出氣孔（分別提供給目標設備的一正一反動作的氣源）、1個正動作排氣孔和1個反動作排氣孔（安裝消聲器）。 對于小型自動控制設備，氣管一般選用8~12mm的工業膠氣管。電磁閥一般選用日本SMC（高檔一點，不過是小日本的產品）、中國臺灣亞德客（實惠，質量也不錯）或其它國產品牌等等。 在電氣上來說，兩位三通電磁閥一般為單電控（即單線圈），兩位五通電磁閥一般為雙電控（即雙線圈）。線圈電壓等級一般采用DC24V、AC220V等。 兩位三通電磁閥分為常閉型和常開型兩種，常閉型指線圈沒通電時氣路是斷的，常開型指線圈沒通電時氣路是通的。 常閉型兩位三通電磁閥動作原理：給線圈通電，氣路接通，線圈一旦斷電，氣路就會斷開，這相當于“點動”。 常開型兩位三通單電控電磁閥動作原理：給線圈通電，氣路斷開，線圈一旦斷電，氣路就會接通，這也是“點動”。 兩位五通雙電控電磁閥動作原理：給正動作線圈通電，則正動作氣路接通（正動作出氣孔有氣），即使給正動作線圈斷電后正動作氣路仍然是接通的，將會一直維持到給反動作線圈通電為止。 給反動作線圈通電，則反動作氣路接通（反動作出氣孔有氣），即使給反動作線圈斷電后反動作氣路仍然是接通的，將會一直維持到給正動作線圈通電為止。這相當于“自鎖”。 基于兩位五通雙電控電磁閥的這種特性，在設計機電控制回路或編制PLC程序的時候，可以讓電磁閥線圈動作1~2秒就可以了，這樣可以保護電磁閥線圈不容易損壞。
