What is a Proximity Sensor?

A proximity sensor is an electronic sensor capable of detecting the presence of nearby objects without physical contact. It emits an electromagnetic field or a beam of electromagnetic radiation (for example: infrared) and then looks for changes in the return signal or field. The object that is being sensed is the proximity sensor's target. Depending on the proximity sensor targets, different sensors may be used. For example, an inductive proximity sensor requires a metal target, whereas a capacitive photoelectric sensor may be suitable for a plastic target. 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.

Types of Proximity Sensors

There are many different kinds of proximity sensors. At Future Electronics we stock many of the most common types categorized by type, supply current, supply voltage, packaging type and output type. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common values for supply current are 10 mA and 15 mA. We also carry proximity sensors with supply current as high as 500 mA. Supply voltages can be up to 200 V, with the most common chips having a supply voltage of 2.7 to 3.6 V and 2.7 to 5.5 V.

Applications for Proximity Sensors:

Proximity sensors have a wide range of applications including:

  • Parking assistance for car bumpers that sense the distance to other nearby cars or objects during the parking procedure
  • 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 that come in close proximity with the user's face

Choosing the Right Proximity Sensor:

When you are looking for the right proximity sensors, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Supply Current (400 to 160000 nA, 10 mA, 15 mA,…), Type (Capacitive, Detector, Magnetic, Touch Key Controller, Touch Pad Controller) and Supply Voltage (up to 200 V) to name a few. You will be able to find the right semiconductor chip for a capacitive proximity sensor, inductive proximity sensor, long range proximity sensor, 3gs proximity sensor, car proximity sensor, ultrasonic proximity sensor, infrared (IR) proximity sensor, RFID proximity sensor, wireless proximity sensor, proximity sensor alarm, laser proximity sensor, micro proximity sensor, ultrasonic proximity sensors, USB proximity sensor, microwave proximity sensor or to design a proximity sensor IC (integrated circuit).

Proximity Sensors in Production Ready Packaging or R&D Quantities

If the quantity of proximity sensors that you require is less than a full reel, we offer customers many of our proximity sensor products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
