Features And Benefits of Proximity Sensors

A proximity sensor is device which is used to detect objects which are at a distance without contacting them physically. There are various types of sensors available today. These sensors detect the objects by emitting a beam or using an electromagnetic field from the sensor that detects the changes in the electromagnetic field.

There are various types of proximity sensors which include the capacitive, inductive, photoelectric and ultrasonic. The long range sensors are used to detect objects which are nearby. These sensors are mainly used in navigation systems and ships to detect obstructions in its path. Short range sensors are used in various security systems and electronic equipments. These sensors are used to warn about near by objects.

Proximity sensors used in navigation vessels and ships utilize SONAR system or Sound Navigation and ranging to determine the proximity of objects in the seas or oceans. Electromagnetic radiation is also used to determine the proximity of the objects.

These sensors were used at first to track the movements of aircrafts and ships. Later on it was used for automobiles and other appliances.

Proximity sensors are used in most of the automobiles as it helps to detect near by objects and vehicles. It is usually situated at the rear of the vehicles so as to alert the drivers of approaching cars or other vehicles.

These sensors are also used in certain home appliances to ensure that windows and doors are shut. Most of the modern equipments such as phones and computer screens have proximity sensors which determine the proximity of the screen and the face of the user.

Today proximity sensors are used in most of the consumer electronics and automated industry. It is used on the arms of robots to detect materials, iPhone, automatic doors and so forth.

It is used in roller coasters, conveyor systems, anti-aircraft warfare and many other applications. It is also used in aviation field as ground proximity warning system. It is also used in large steam turbines, motors and compressors.
