GP2Y0A21YK0F is a distance measuring sensor unit produced by SHARP, with a measuring range of 10 to 80 cm and an analog output function. It is suitable for applications such as sanitary equipment and illumination control.
The GP2Y0A21YK0F is a distance‑measuring sensor unit that combines a position‑sensitive detector, an infrared emitting diode and a signal‑processing circuit. It outputs a voltage proportional to the detected distance and can also be used as a proximity sensor. Typical applications include touch‑less switches, robot cleaners, energy‑saving devices and amusement equipment.
Key electrical characteristics include a supply voltage of 4.5‑5.5 V, typical current consumption of 30 mA, and a measuring range of 10‑80 cm. The device is supplied in a compact 29.5 × 13 × 13.5 mm package and complies with RoHS directives. The datasheet also provides absolute maximum ratings, timing charts, application notes, and packaging information.
