GP2Y0A21YK0F Sharp Reflective Optical Sensor

Distance Measuring Sensors, Sharp

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
