光電式傳感器非接觸地探測物體，廣泛用于許多自動化領域，如管理系統、機械制造、包裝工業等。
西門子為這些不同的應用領域提供了極大范圍的產品，從直徑只有4 mm、可探測距離50
mm的BERO微型接近開關到傳輸距離達25 m耐用方形K80傳感器，再到極精密的BERO激光傳感器，傳輸距離達50 m。
漫射傳感器發射器和接收器裝在一個盒子中，發射器發射的光束由被探測物反射。這種工作方式最簡單，因為它只需要安裝和連接一個傳感器，不需安裝反射器。 帶背景噪音抑制的漫射傳感器發射器和接收器裝在一個盒子中，發射器發射的光束由被探測物反射。另外，還可以設置一個距離，探測到使在此之后的特體不被(背景抑制)。 反射傳感器發射器和接收器裝在一個盒子中，反射器通常固定安裝。光束經反射器反射到接收器。只需在一端接線。 直通光束傳感器發射器和接收器分別安裝在不同的盒子中，當光束被中斷時，輸出開關信號。直通光束傳感器傳輸距離最長。帶光纖的光電式傳感器光纖在光學中被稱為"延伸的眼睛"，用于連接傳感器。由于其高密度和靈活性，它還是對微小且不易接近物體的理想探測手段。 激光傳感器激光傳感器的功能與"普通的"光電傳感器基本相同。然而激光傳感器可探測更微小的物體，且精度遠高于后者。 帶模擬輸出的激光傳感器帶模擬輸出的激光傳感器探測距離異常精確，模擬輸出的線性度高，分辨率可達20um。 它是直通光束傳感器，發射器和接收器相隔固定距離地安裝在同一盒中，還可用于探測半透明物體的對比度。顏色傳感器由于有學習功能，顏色傳感器可簡易、地探測不同顏色或顏色范圍。 對比傳感器與顏色傳感器相似，只是它探測亮度和對比度，如：標記或灰色調。而且因為有學習功能，可以優化設置。| sensing distance | 6,5 m | |||
