The QRD1113/14 reflective sensor consists of an infrared light emitting diode and an NPN silicon photo-darlington mounted side by side in a black plastic housing. Both the coaxial radiation of the emitter and the coaxial response of the detector are normal to the end face of the QRD1113/14. The photodarlington responds to the radiation emitted by the diode only when a reflective object or surface is within the detector's field of view.
