The 4N35 is an optocoupler that consists of a gallium arsenide infrared LED and a silicon NPN phototransistor. When the input signal is applied to the LED in the input terminal, the LED lights up. After receiving the light signal, the light receiver then converts it into electrical signal and output..

The QRD1114 is a half-LED, half-phototransistor, all infrared reflective optical detector. It can be used to sense objects in close proximity or even detect the difference between black and white surfaces. Photodetectors like these are critical components for projects ranging from line-followin..
