GP2Y0A21YK0F
GP2Y0A21YK0F
Distance Measuring Sensor Unit
Measuring distance: 10 to 80 cm
Analog output type
Description
■Agency
approvals/Compliance
1. Compliant with RoHS directive (2002/95/EC)
GP2Y0A21YK0F
is a distance measuring sensor unit,
composed of an integrated combination of PSD
(position sensitive detector) , IRED (infrared emitting
diode) and signal processing circuit.
The variety of the reflectivity of the object, the
environmental temperature and the operating duration
are not influenced easily to the 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.
■Applications
1. Touch-less switch
(Sanitary equipment, Control of illumination, etc. )
2. Robot cleaner
3. Sensor for energy saving
(ATM, Copier, Vending machine)
4. Amusement equipment
(Robot, Arcade game machine)
■Features
1. Distance measuring range : 10 to 80 cm
2. Analog output type
3. Package size : 29.5×13×13.5 mm
4. Consumption current : Typ. 30 mA
5. Supply voltage : 4.5 to 5.5 V
