In the finishing of blank parts in automotive and general engineering the presence of components is ensured by means of inductive sensors. In this special case, it is an inductive sensor with reduction factor 1. Irrespective of the materials used (steel, copper, aluminum, ...), the operating distance always remains the same. Another highlight of the inductive sensors used for this application is the electrical and mechanical resistance to external welding fields. Thus, these sensors are especially suitable for use in welding robots.
