Optical proximity sensors are advanced devices used to detect the presence or absence of objects within a certain range without physical contact. Utilizing light-based technology, these sensors emit infrared or visible light and measure the reflection or interruption of this light to determine the proximity of objects. Ideal for applications in automation, robotics, and consumer electronics, they offer high precision and reliability in various environments. Whether for detecting objects on assembly lines or enhancing touchless user interfaces, optical proximity sensors provide a versatile and effective solution for modern sensing needs.
