Infrared Proximity Sensor - Sharp GP2Y0A21YK
We have ✅ 4 available of the SF-SEN-00242 in our Sydney warehouse. An extra 276 units available with a short lead time.
The Sharp GP2Y0A21YK is an infrared proximity sensor with an analogue voltage output that varies with distance — from 3.1 V at 10 cm to 0.4 V at 80 cm. It uses an IR emitter and position-sensitive detector to measure distance, making it unaffected by the colour or reflectivity of most objects.
The sensor terminates in a 3-pin JST connector. Use a JST pigtail cable for easy connection, or solder wires directly to the back of the module.
