GP2Y0D21YK0F Sharp, Reflective Optical Sensor

A range of distance measuring sensors from Sharp utilising infrared emitters and photo-detectors with integrated signal processing circuitry. The devices are available with either analogue or switched (digital) outputs and include both fixed and variable distance sensors. Mounting styles include two-hole surface fixing and through-hole PCB types. Sensing distances covered are 4 cm to 550 cm. Typical uses include object detection in automation, robotics and automotive applications, contactless switching and safety systems.

Analogue output types produce an output voltage related to distance
Digital output types switch at a specified target distance
Insensitive to the colour of target objects
No additional external control circuits are required
