Datasensor inductive proximity sensors belonging to the Basic line were made in the classic cylindrical nickel-plated brass, with diameters ranging from 6.5 to 30 mm. They can detect metal objects from 1.5 mm to 20 mm apart and are available with either a cable or with M8 or M12 standard industrial connectors. 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.
