Product Description

GP2Y0A21YK0F is a distance infrared sensor. It works in range 10..80 cm. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor. The characteristic of the sensor is NOT linear!

Features & Specifications

Distance measuring range: 10 to 80 cm

Analog output type

Package size: 29.5×13×13.5 mm

Consumption current: Typ. 30 mA

Supply voltage: 4.5 to 5.5 V

When the supply voltage is close to the lower boundary of 4.5V, the sensors starts to work not properly.
