The QRD1114 reflective sensor consists of an infrared (IR) 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 QRD1113/14.
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:
- Phototransistor output
- No contact surface sensing
- Unfocused for sensing diffused surfaces
- Compact package
- Daylight filter on sensor (Most important feature)
