Sharp/Socle GP2Y0A51SK0F Analog Distance Sensor 2-15cm

The GP2Y0A51SK0F is the shortest-range Sharp analog distance sensor we carry, featuring a detection range of 0.8″ to 6″ (2 cm to 15 cm). The shorter range gives you higher resolution measurements, and the low minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.

Notes:

1: Typical; can be as low as 50 Hz.
2: Average; this sensor draws current in large, short bursts, which is why it is recommended a 10 µF capacitor or larger be placed across power and ground close to the sensor.
3: Over the range of 2 cm to 15 cm.
