Recognizing and even distinguishing metal under plastic

Diameter and presence control of sheathed metal pipes

How can aluminium be reliably detected under plastic or as a thin foil in the process? Selective inductive sensors specifically distinguish between non-ferromagnetic and ferromagnetic metals – ideal for concealed components and demanding conveying applications.

Reliably detect crown caps
