What are the Benefits of Proximity Sensors?

As the name itself implies, proximity sensors are sensors that can detect objects at certain proximity without even touching them. Different types of sensors can be bought in the market today. The way that these sensors detect objects is by emitting a beam or using an electromagnetic field from the sensor which detects the changes in the electromagnetic field.

Many different kinds of proximity sensors are being used today including the inductive, photoelectric, capacitive, and ultrasonic. If objects are nearby, the long-range sensors are used to detect them. When using sensors in their navigation systems, ships are able to detect obstructions in their paths. It is short-range sensors that are used in various security systems and electronic equipment. With these sensors, a warning is given when objects are nearby.

Navigation vessels and ships use proximity sensors which utilize sonar systems or sound navigation so that they can determine the proximity of objects underwater. Electromagentic radiation can also be used to determine the proximity of objects.

These sensors were used first to track the movements of ships and aircrafts. Automobiles and other appliances also used these sensors.

Automobiles that use proximity sensors are able to detect object or vehicles that are nearby. In order to alert approaching cars or other vehicles, proximity sensors are placed in the rear of the automobile.

To ensure that windows and doors are shut, proximity sensors are also used in certain home appliances. Proximity sensors are also used in most of the modern equipment like phones and computer screens to determine the proximity of the screen and the face of the user.

Most of the consumer electronics and automated industry use proximity sensors. When people make robots, proximity sensors are used in their arms to detect materials; you can also use it in automatic doors, iPhones, and more.

Roller coasters, anti-aircraft warfare, conveyor systems, and many other applications use proximity sensors. As ground proximity warning systems, it is also used in the aviation field. The use of proximity sensors is also seen in large steam turbines, compressors, and motors.

In order to detect metallic objects inductive sensors are used. An inductive proximity sensor operates under the electrical principles of inductance. The accuracy of inductive proximity sensors is one of its advantages compared to other technologies. The switching rate of the inductive proximity sensor is high and it can work even in harsh environmental conditions.

The principles used in inductive sensors are also used in capacitive sensors. Their main difference is that the capacitive sensors produce electrostatic field instead of an electromagnetic field. Capcitive sensors are able to detect metallic as well as non-metallic objects. High speed and good stability are its other advantages. Capacitive sensors are good in terms of power usage and are low in cost.

If you want to buy different types of proximity sensors, you can do so online at reasonable prices.
