GP2Y0A02YK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector), IRED (infrared emitting diode) and a signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to distance detection because of adopting the triangulation method.
This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.

Input Voltage: 4.5V ~ 5.5 V
Working Current: 33 mA
Distance Range: 20cm ~ 150cm
Output Type: Analog
Update Period: 38 ± 10 ms
Size: 29.5mm × 13mm × 21.6mm

Touch-less switch (Sanitary equipment, Control of illumination, etc.)
Sensor for energy saving (ATM, Copier, Vending machine, Laptop computer, LCD monitor)
Amusement equipment (Robot, Arcade game machine)

The lens of this device needs to be kept clean. There are cases that dust, water or oil and so on deteriorate the characteristics of this device. 
1- Please consider in actual application.
2- Please don’t do the washing. Washing may deteriorate the characteristics of the optical system and so on.
3- Please confirm resistance to chemicals under the actual usage since this product has not been designed against washing.
4- In order to stabilize the power supply line, we recommend to insert a by-pass capacitor of 10μF or more between Vcc and GND near this product.
5- There are some possibilities that the internal components in the sensor may be exposed to excessive mechanical stress. Please be careful not to cause any excessive pressure on the sensor package and also on the PCB while assembling this product.
