Proximity Sensor

Proximity actually meaning is nearness, so the proximity sensor is a sensor able to detect the presence of nearby objects by generating frequency without any contact with the object. Electromagnetic radiation is emitted by proximity sensor for instance and looks for changes in the field or return signal. The object being sensed is often referred to as proximity sensors target depending on the proximity sensor target.

Proximity sensor has a long functional life and can be available in various shapes and materials such as plastic, metallic or having circular and rectangular shape. Some proximity sensors are the combination of metallic and plastic. The proximity sensor has high reliability due to the absence of mechanical parts and the lack of physical contacts between sensor and the target. A proximity sensor that is adjusted to very short range can often be used as touch switch. Proximity sensors are commonly used in industrial application from manufacturing and food production to recycling. They are also used in vehicles for detecting the proximity of other vehicles relative to one own car as well as for parking such as how many cars enter to the parking area, assist function in mobile devices especially phones. The proximity sensor is used to detect whether a user face is close to the phone during a phone call from opening the screen to turn off to prevent false touches on the touch screen.
