We also carry two shorter-range versions of this sensor: the Sharp GP2Y0A41SK0F analog distance sensor (4 – 30 cm) and the Sharp GP2Y0A21YK0F analog distance sensor (10 – 80 cm). These two analog distance sensors have identical packages and pin-outs, making it easy to swap one version for another should your application requirements change, and they have the same mounting hole locations and cable connector as this GP2Y0A02YK0F.
For very short-range detection applications, we carry a 2-15 cm analog Sharp distance sensor. We also carry three digital Sharp distance sensors that have low minimum detection distances and a high 400 Hz update rate. They are available with a 5 cm, 10 cm, or15 cm range and simply tell you if something is in their detection range, not how far away it is. They are smaller than the analog Sharp distance sensors and draw less current.
