Product Overview
The GP2Y0A51SK0F is an integrated distance measuring sensor unit that utilizes a triangulation method for accurate detection. It comprises a PSD (position sensitive detector), IR-LED (infrared emitting diode), and a signal processing circuit. This sensor is designed to be minimally influenced by object reflectivity, environmental temperature, and operating duration, providing a voltage output proportional to the detected distance. Its compact size and short measuring cycle make it suitable for applications such as cleaning robots, personal robots, and sanitary equipment, where it can also function as a proximity sensor.
