Proximity sensors are devices which detect presence of objects near its boundaries or even if the objects are certain distance away from the sensors. Inductive proximity sensors are solely for the detection of metal objects. This means that the sensor either energizes an output signal wire with a small amount of electricity, or not. An alternating magnetic field is generated in front of these windings. Inductive typedetects metallic objects such as aluminium, iron, copper and brass etc. In brief we can also say that Sensors which convert information on the movement or presence of an object into an electrical signal are called proximity sensors. This is why they’re often called non-contact sensors. A proximity sensor is an electronic sensor that can detect the presence of objects within its vicinity without any actual physical contact.

It can also be used to measure the distance from a robot to some object. Inductive Proximity Sensors are roughly classified into the following three types according to the operating principle: the high-frequency oscillation type using electromagnetic induction, the magnetic type using a magnet, and the capacitance type using the change in capacitance. In order to avoid accidental touch events, your phone's touchscreen goes black during calls, when it's very close to your ear. Key to their operation is that they don’t require physical contact with the target or object being sensed. They’re used to sense the presence of objects or materials and then either initiate some action or simply flag their presence or absence. The simplest proximity sensors do not measure distance. In order to sense objects, the proximity sensor radiates or emits a beam of electromagnetic radiation, usually in the form of infrared light, and senses the reflection in order to determine the object's proximity or distance from the sensor.
