Proximity sensor advantages and disadvantages

A proximity sensor can detect an object. When the object approaches within the detection range and then the boundary of the sensor. Proximity sensor includes all the sensor that performs non-contact detection in comparison to the sensor such as a limit switch, and that can detect the object by physically contacting them. Here this article gives information about the advantages and disadvantages of the proximity sensor to better understanding this topic.

Advantages of proximity sensor:

  • It can detect both metallic and nonmetallic targets.
  • It has good stability.
  • High speed provided.
  • High switching rate.
  • Work in harsh environmental conditions.
  • Low cost and power consumption.
  • A capacitive sensor is good in terms of power usage.
  • They are useful and can help with many security problems.

Disadvantages of proximity sensor:

  • They are affected by temperature and humidity.
  • Difficulties in designing.
  • The operating range may be limited.
  • A capacitive proximity sensor is not as accurate to compare to the inductive sensors.
  • It detects only the metallic target.
  • They can be easily set off and cause a problem.
  • They are expensive than inductive and capacitive sensors.
