Product Description
Sharp GP2Y0A51SK0F Analog Distance Sensor 2-15cm detects nearby objects and represents their distance as an analog voltage. This infrared sensor supports microcontroller-based measurements that require distance values or adjustable detection thresholds. Its low minimum detection distance allows objects close to the sensor to be measured.
The output connects to an analog-to-digital converter for distance measurement or a comparator for threshold detection. Operation requires a 4.5 to 5.5 V supply and a suitable connection. The sensor uses a three-pin JST ZH connector; a connection cable is not included.
Highlights
- Detection of nearby objects from a distance of 2 cm.
- Short measuring range for higher-resolution distance measurements.
- Analog voltage output for connection to analog-to-digital converters.
- Adjustable threshold detection through an external comparator.
- Lead-free, RoHS-compliant version.
Technical Features
- Sensor model: GP2Y0A51SK0F.
- Measuring range: 2 to 15 cm.
- Operating voltage: 4.5 to 5.5 V.
- Average current consumption: 12 mA.
- Output: analog voltage; typical voltage differential across the measuring range: 1.65 V.
- Update period: 16.5 ± 4 ms; update rate: 60 Hz.
- Connector: JST ZH, 3 pins, 1.5 mm pitch.
- Dimensions: 27 × 13.2 × 14.2 mm.

Application Areas
- Measuring nearby object distances through a microcontroller's analog input.
- Threshold detection using an external comparator with an adjustable switching threshold.
- Detecting objects within a measuring range of 2 to 15 cm.
Notes
- A capacitor of at least 10 µF between Vcc and GND near the sensor is recommended to stabilize the supply.
- JST PH cables and 0.1-inch connectors are incompatible; a suitable JST ZH cable is available separately.
- The mounting holes do not fit Pololu brackets intended for other Sharp distance sensors.
- The output voltage is not directly proportional to distance; conversion must account for the sensor's characteristic curve.
What's Included
