光電開關工作原理
由振蕩回路產生的調制脈沖經反射電路后，由發光管GL輻射出光脈沖。當被測物體進入受光器作用范圍時，被反射回來的光脈沖進入光敏三極管DU。并在接收電路中將光脈沖解調為電脈沖信號，再經放大器放大和同步選通整形，然后用數字積分或RC積分方式排除干擾，最后經延時（或不延時）觸發驅動器輸出光電開關控制信號。
光電開關一般都具有良好的回差特性，因而即使被檢測物在小范圍內晃動也不會影響驅動器的輸出狀態，從而可使其保持在穩定工作區。同時，自診斷系統還可以顯示受光狀態和穩定工作區，以隨時監視光電開關的工作。
光電開關的特點
MGK系列光電開關是現代微電子技術發展的產物，是HGK系列紅外光電開關的升級換代產品。與以往的光電開關相比具有自己顯著的特點：
具有自診斷穩定工作區指示功能，可及時告知工作狀態是否可靠；
對射式、反射式、鏡面反射式光電開關都有防止相互干擾功能，安裝方便；
對ES外同步（外診斷）控制端的進行設置可在運行前預檢光電開關是否正常工作。并可隨時接受計算機或可編程控制器的中斷或檢測指令，外診斷與自診斷的適當組合可使光電開關智能化；
響應速度快，高速光電開關的響應速度可達到0.1ms，每分鐘可進行30萬次檢測操作，能檢出高速移動的微小物體；
采用專用集成電路和先進的SMT表面安裝工藝，具有很高的可靠性；
體積�。ㄗ钚H20×31×12mm）、重量輕，安裝調試簡單，并具有短路保護功能。
