Note: If the target is a nonferrous metal, the operating distance of the proximity sensor decreases. However, with a piece of foil measur-
ing about 0.01 mm (0.0004 inch) in thickness, the detecting distance is equivalent to that with a ferrous metal. Note that the
proximity sensor cannot detect extremely thin evaporated films and non-conductive targets.
