Inductive sensor contains conductive paths (24,26) on circuit board (16,18), forming at least part of coil, to which is allocated coil core (20). Circuit board is of multilayer type with outer layers (16,18) carrying conductive path sections.Contacts (28) are used to connect conductive path sections, thus forming complete coil. Coil core (20,22) is sandwiched by outer layers. Typically coil core is foil (22) of amorphous metal. Each outer layer may be separate circuit board fitted with further electronic components, e.g. evaluating circuit. |
