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.

FEATUREs
■ Photodarlington output
■ Unfocused for sensing diffused surfaces
■ Low cost plastic housing
■ Designed for paper path and other non-contact surface sensing
