Safe Capacitive Sensors have Unique Advantages over Other Technologies


Capacitive sensors measure their electrical capacity versus their surroundings. A person approaching such a sensor will be detected independently of any garment worn. Out of many possible applications, only three will be mentioned here:

  • the use in automobiles delivering geometrical information to airbag sensors (translation of this paragraph will follow),
  • roller based machines,
  • and collaborative robots.

With roller based machines, capacitive sensors work especially well in form of capacitive switch rods if the processed material is electrically nonconductive.
