Inductive proximity switch, particularly all-metal inductive proximity switch for reacting to approach of electrically conductive object, has inductor formed as low temperature penetrating ceramic body with conductor path as shielding layer

摘要

The inductive proximity switch has a generator (2) for generation of a transmission signal, an inductor (3) for generating an alternating magnetic field influenced by a conductive target and a control unit (5) for generating a switch signal. The inductor is designed as low temperature penetrating ceramic body with multiple primary conductor paths. The ceramic body comprises ferrite (7), and has a secondary conductor path, which serves as shielding layer (6) and is connected with the mass.
