Packages for coil actuated position sensors
An apparatus comprises one or more substrates and one or more coils. At least one of the coils is configured to produce a first magnetic field that induces eddy currents in a conductive target, which generates a reflected magnetic field. One or more magnetic field sensing elements supported by the o...

| description | An apparatus comprises one or more substrates and one or more coils. At least one of the coils is configured to produce a first magnetic field that induces eddy currents in a conductive target, which generates a reflected magnetic field. One or more magnetic field sensing elements supported by the one or more substrates detect the reflected magnetic field. A conductive support structure supports the one or more substrates. The support structure includes a gap in an area adjacent to the one or more coils so that the support structure does not generate a reflected magnetic field in response to the first magnetic field. |
