Datalogic inductive and capacitive proximity offers a reliable detection where photoelectric is not applicable. Datasensor inductive sensors are used for metal parts at close distance, wheras Datasensor capacitive sensors are suggested for any material inside opaque containers. Datalogic inductive proximity sensors generate a magnetic field from their detection faces. Whenever a detectable object moves into the sensor’s field of detection, Eddy currents build up in the target and dampen the sensor’s magnetic field. This effect triggers the sensor’s output. Since a current in the target is needed for detection, inductive proximity sensors are uniquely suited for detection of all types of metals.
