Inductive sensors can be available in both ac and dc supply operated.

I would appreciate your support in this way! Inductive proximity sensors: I may make a commission if you buy the components through these links. Ultrasonic Proximity Sensor Amazon Purchase Links: 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. 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. Proximity sensors are commonly used in industrial application from manufacturing and food production to recycling. A proximity sensor that is adjusted to very short range can often be used as touch switch. The proximity sensor has high reliability due to the absence of mechanical parts and the lack of physical contacts between sensor and the target. Some proximity sensors are the combination of metallic and plastic. 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. The object being sensed is often referred to as proximity sensors target depending on the proximity sensor target. Electromagnetic radiation is emitted by proximity sensor for instance and looks for changes in the field or return signal. 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.
