A proximity sensor can detect the presence of nearby objects without the use of physical contact. The proximity sensor accomplishes this by using an electromagnetic field, or infrared radiation. The sensor then looks for changes within the return signal or field and adjusts itself accordingly based on pre-programmed instructions. Proximity sensors have a long functional life and high reliability due to the absence of mechanical parts and the lack of physical contact between the sensor and the target. A proximity sensor that is adjusted to a very short range can often be used as a touch switch.

Proximity Sensor Options

Inductive proximity sensors are the preferred choice for many applications that require accurate, non-contact detection of metallic objects in machinery or automation equipment. Control Components carries a wide selection of proximity controls that will fit most any automotive, material handling, packaging equipment, or production machine application. Some of our proximity control and sensor components options include the following:
  • Barrel diameters from 3-30 mm
  • 2, 3 or 4 Wire Outputs
  • Connector or Fixed Lead
  • Extended Sensing Ranges
  • Rugged Stainless Steel Sensing Face

Proximity Electronic Sensor Industrial Applications 

Proximity sensors and proximity control components are regularly used for a wide range of industrial applications, some of which include:
  • Parking assistance for car bumpers
  • Conveyor systems
  • Vibration measurements of rotating shafts in machinery
  • Roller coasters
  • Sheet break sensing in paper machines
  • Ground proximity warning systems for aviation safety
  • Anti-aircraft warfare
  • Mobile phones
  • Touch screens on mobile devices

Inductive Proximity Sensors

Inductive proximity sensors are the preferred choice for the majority of applications requiring accurate, non-contact detection of metallic objects in machinery or automation equipment. Inductive proximity controls consist of an induction loop of which an electric current generates a magnetic field, which collapses generating a current that falls toward zero from its initial trans when the input electricity ceases.
 
The inductance of the loop changes according to the material inside it and since metals are much more effective inductors than other materials the presence of metal increases the current flowing through the loop. This change can be detected by sensing circuitry. This then signals some other device whenever metal is detected. Some of the more common applications for inductive proximity sensors, include:
  • Traffic lights
  • Car washes
  • Metal detectors

Capacitive Proximity Sensors

Capacitive sensors detect both metal and non-metal objects they can also sense through insulating materials such as plastic and wood. Capacitive sensors are often used to detect fill levels of liquids, pellets, and powders through containers. Capacitive proximity controls are used for touchscreens for mobile phones and handheld electronic devices, other applications include:
  • Digital audio players
  • Computer mice
  • Tablets
  • Other touchscreen devices
