QRD1113 onsemi, IR Phototransistor, Through Hole 4-Pin Custom 4L package

The QRD1113/14 reflective sensor consists of an infrared emitting diode and an NPN silicon photo darlington 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 QRD1113/14. The photo darlington responds to radiation emitted from the diode only when a reflective object or surface is in the field of view of the detector.
