What is a Proximity Sensor?

A proximity sensor is a non-contact device that detects the presence of an object when it enters its field of view, also known as the “target.” Depending on the type of proximity sensor, the sensor may detect a target via sound, light, infrared radiation (IR), or electromagnetic fields. Phones, recycling facilities, self-driving cars, anti-aircraft systems, and production lines all use proximity sensors. There are numerous varieties of proximity sensors, and they all detect targets differently. The inductive proximity sensor and the capacitive proximity sensor are the two types of proximity sensors that are most frequently utilized.

What are Proximity Switches?

The terms proximity switch and proximity sensor are frequently used interchangeably, but they should not be confused. A proximity sensor, as previously defined, is a non-contact component that detects the presence of objects within its sensing range. A proximity switch, on the other hand, is a specific component that opens or closes the electrical circuit when the sensor detects the absence or presence of an object.

Features of Proximity Sensor

We’ll look at the proximity sensor’s features to better understand what it’s all about. It has the following features:

Contactless Sensing

Since proximity sensors do not physically touch the object they are detecting, the object is not scratched or otherwise harmed. Proximity Sensors are able to detect the presence of an object electrically, without touching it, unlike devices like limit switches that detect an object by making contact with it.

Unaffected by Surface Condition

Proximity sensors are virtually completely unaffected by an object’s surface color because they detect physical changes in an object.

Suitability for a Wide Range of Applications

In contrast to typical optical detection, proximity sensors may be used in moist environments and throughout a wide variety of temperatures. They work in a temperature range of -40 to 200 °C.

Phones with Android or iOS operating systems can also use proximity sensors. It uses basic IR technology to turn the display on and off depending on your needs. For instance, it disables your display when you’re using the phone so you won’t unintentionally activate anything while holding it up to your cheeks!

Longer Service Life

Since a proximity sensor relies on semiconductor outputs, its operation is not reliant on moving parts. As a result, it often has a longer service life than standard sensors.

High-Speed Respons

Proximity sensors give a faster reaction rate when compared to switches, where touch is necessary for detecting.

Chemical and Dirt Resistant

Proximity Sensors, in contrast to optical detection techniques, can be employed in environments with water or oil use. Dirt, grease, or water on the object being detected have almost no impact on the detection process. There are various models with fluororesin casings for good chemical resistance.

Non-physical Contact

Proximity Sensors are impacted by environmental conditions, items in the immediate area, and other Sensors, as opposed to switches, which depend on physical touch. Interaction with other sensors has an impact on proximity sensors, both inductive and capacitive. Because of this, care must be taken to avoid mutual interference when installing them. Inductive proximity sensors must be protected from the effects of nearby metallic items, while capacitive proximity sensors must be protected from the effects of all nearby objects.

Two-wire sensors exist

Signal and power lines are integrated. Internal components could be harmed if only the power line is wired. Always add a load.

Proximity Sensor: Operating Principle

When a target enters the field of a non-contact sensor like a proximity sensor, the sensor senses the target’s presence. Depending on the type of sensor, a target can be detected via electromagnetic, infrared, or sound waves. These sensors are used in self-driving automobiles, assembly lines, anti-aircraft systems, recycling facilities, and cell phones. There are various types of proximity sensors available, and they all detect targets differently.

Proximity Sensor Types

There are several sorts of proximity sensors used in different applications but each type of sensor detects an object in a different way; they are inductive proximity, capacitive proximity, ultrasonic proximity, and optical proximity. But the most frequently utilized proximity sensors are inductive proximity & capacitive proximity.

Inductive Proximity Sensor

These sensors for metal detection are non-contact devices. The induction law is largely what drives this type of sensor. When a metallic object comes close to it, the oscillator is driven through the coil. This sensor comes in two variations and contains four crucial parts, which are covered in more detail below.
Unshielded and shielded inductive proximity sensors are available.

Shielded Version

In the shielded version, the sensor coil sides are covered, concentrating the electromagnetic field created in the face.

Unshielded Version

The generated electromagnetic field through the sensor coil is clear in the unshielded form, allowing for longer and wider detecting distances. There are four main parts to an inductive proximity sensor: an oscillator, a coil, a Schmitt trigger, and an output switching circuit.

An electromagnetic detecting field can be produced when the sensor coil is given an AC. Eddy currents can arise when a metal object is positioned close to the magnetic field, changing the coil’s inductance. When the coil’s inductance changes, the circuit adjusts the sensor’s output switch, which is continuously monitoring.

Here, these sensors constantly oscillate in the absence of a target, and only when a target is present will the switch be activated. The inductive proximity sensor is mostly utilized in industrial and security applications such as metal object identification, the detection of landmines, the creation of automated machines, etc.

Capacitive Proximity Sensor

These contactless sensors are used to detect both metallic and non-metallic items, such as powders, liquids, granular materials, etc. This sensor detects changes in capacitance to function.
It has an oscillator, switching circuit for the output, and a Schmitt trigger, just like the inductive kind.

The key distinction is that it has two charging plates, one for capacitance that is inside and one that is exterior. The connection between these two plates can be made by using the external plate as the detecting surface and connecting the inside plate to the oscillator.

There is an electrostatic field created by this type of proximity sensor. When an object enters the detecting zone, the plates’ capacitance rises as well, increasing the oscillator’s amplitude gain. The sensor’s output switch is turned on by this gain. These sensors only begin to oscillate when the target is nearby.
Among the uses for capacitive proximity sensors include industrial operations, moisture management, touch applications, and others.

Ultrasonic Proximity Sensor

These sensors are a particular type of proximity sensor that is applied in a number of manufacturing and automation applications. This sensor’s primary functions are object detection and distance measuring. These sensors are employed in the preparation of food, drinks, and various packaging applications.

These sensors have a frequency range that is about 20 kHz higher than the human hearing range. This sensor’s fundamental working principle is to send an ultrasonic signal and receive a signal in return. The target’s distance can be calculated using the time difference between these signals.

Even while they can also be installed in separate units, such as with some photoelectric sensors through separate detectors and emitters, a typical design includes both the transmitter and the receiver within the same physical enclosure. The amount of wiring and installation can be reduced by placing the transmitter and receiver inside the same unit.

Since these sensors detect sound rather than light, they can be used in situations where optical sensors cannot, such as detecting plain plastic labels and items or highly reflective surfaces. Additionally, they are resistant to common pollutants including dust, moisture, and ambient light.

Optical Proximity Sensor

Generally speaking, these sensors are less expensive than inductive and capacitive varieties. These may be arranged into small spaces, making them useful in automated systems. They are also known as light beam sensors.

A sensor and a light source are both present in an optical proximity sensor. While a light source produces light, a sensor is employed to detect it. The photodiode-like semiconductor used as the light sensor in this sensor typically produces less light after being illuminated by light.

Different proximity sensor kinds, such as through-beam, retro-reflective, and diffuser, are available. Computer alarm systems, copier machines, light fixtures, etc. are just a few examples of where optical proximity sensors are used.

Magnetic Proximity Sensor

The magnetic proximity sensor merely uses mechanical principles to detect the magnetic field. They locate magnetic targets by detecting their magnetic fields, which serve as indicators of their presence. It starts the switching process once it is within the sensor’s detecting range.

These sensors are mostly employed for non-contact location detection outside of the normal inductive sensor ranges. This sensor uses Hall Effect sensors in lieu of GMR inductive, reed switches, magnetoresistive, and variable reluctance as its operating principles.

Proximity Sensor Applications

Proximity sensors can be used in a variety of settings and for a wide range of applications. They are useful in any application where an object must be detected within a specific range. This may include:

– Detection of standard object position
– Transportation, logistics, and supply chain management
– Quality control and inspection
– Process management
– detection of levels
– Manufacturing and processing of food
– Agriculture
They can also be used in environments where oil or water is present, giving them a significant advantage over other detection methods. Depending on the dielectric constant of the object, capacitive proximity sensors can detect media such as water, resin, and metal. As discussed below, different types of sensors are best suited to detecting different objects:
Capacitive proximity sensors – metals, liquids, water, resin, powders
Inductive proximity sensors – metals including aluminum, copper, brass, and iron
Magnetic proximity sensors – magnets


Choosing the right proximity sensor capable of detecting nearby objects without physical contact is dependent on the target’s size, material, spacing, and sensing distance. In this article you’ll be guided on how to choose the right proximity sensor for your needs. In addition, listed on this are the top proximity sensor manufacturers in the world.
