QRD1114 Reflective Object Sensor

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)
