1. Multilayer assembly intended to be used in an inductive detector, characterized in that it comprises at least four stacked parallel separated layers, namely:
- a layer (C1, C10, C100) comprising a first shielding element for a first coil,a layer (C2, C20, C200) comprising a first coil,a layer (C3, C50, C600) comprising a second coil,a layer (C4, C60, C800) comprising a first shielding element for the second coil,and in that said layers are separated from one another by connecting layers (CL), one of said connecting layers, referred to as an intermediate connecting layer (CLm), having a determined thickness (e) greater than those of the connecting layers (CL) separating the other layers from one another.

Abstract
The invention relates to a shielded double-coil multilayer assembly intended to be used in an inductive detector. This multilayer assembly comprises a plurality of stacked parallel separated layers, namely:
- a layer (C1) comprising a first shielding element for a first coil,
- a layer (C2) comprising all or part of a first coil,
- a layer (C3) comprising all or part of a second coil,
- a layer (C4) comprising a first shielding element for the second coil.
