A proximity detector is used to sense the presence or absence of nearby objects without physical contact. It typically employs various technologies, such as infrared, ultrasonic, or electromagnetic fields, to detect objects within a specified range. Common applications include automated systems in manufacturing, security alarms, and consumer electronics like smartphones for features such as screen activation and gesture recognition. Overall, proximity detectors enhance safety and efficiency in various settings.
