Description
The QRD1313 reflective sensor consists of an infrared emitting
diode and an NPN silicon photodarlington mounted side by side
in a black plastic housing. The on-axis radiation of the emitter
and the on-axis response of the detector are both perpendicular
to the face of the QRD1313. The photodarlington responds to
radiation emitted from the diode only when a reflective object or
surface is in the field of view of the detector.
