P+F光電傳感器是通過把光強度的變化轉(zhuǎn)換成電信號的變化來實現(xiàn)控制的。
P+F光電傳感器在一般情況下，有三部分構(gòu)成，它們分為：發(fā)送器、接收器和檢測電路。
發(fā)送器對準目標發(fā)射光束，發(fā)射的光束一般來源于半導體光源，發(fā)光二極管（LED）、激光二極管及紅外發(fā)射二極管。光束不間斷地發(fā)射，或者改變脈沖寬度。接收器有光電二極管、光電三極管、光電池組成。在接收器的前面，裝有光學元件如透鏡和光圈等。在其后面是檢測電路，它能濾出有效信號和應(yīng)用該信號。
P+F光電傳感器在不同所制成的光學測控系統(tǒng)是多種多樣的,按光電元件（光學測控系統(tǒng)）輸出量性質(zhì)可分二類,即模擬式光電傳感器和脈沖（開關(guān)）式光電傳感器.模擬式光電傳感器是將被測量轉(zhuǎn)換 光電傳感器
成連續(xù)變化的光電流,它與被測量間呈單值關(guān)系.模擬式光電傳感器按被測量（檢測目標物體）方法可分為透射（吸收）式,漫反射式,遮光式（光束阻檔）三大類.所謂透射式是指被測物體放在光路中,恒光源發(fā)出的光能量穿過被測物,部份被吸收后,透射光投射到光電元件上;所謂漫反射式是指恒光源發(fā)出的光投射到被測物上,再從被測物體表面反射后投射到光電元件上;所謂遮光式是指當光源發(fā)出的光通量經(jīng)被測物光遮其中一部份,使投射到光電元件上的光通量改變,改變的程度與被測物體在光路位置有關(guān).
