Abstract
An assembly includes a housing. A first set of coils is mounted to the housing. The first set of coils extends in an axial or rotational direction along the housing for a first length. A second set of coils is mounted to the housing. The second set of coils extends in the axial or rotational direction along the housing for a second length that is shorter than the first length. A core member includes a first core and a second core in series with one another in an axial direction along the core member. The core member is moveable within the housing along a stroke. For at least a first portion of the stroke, the first core is within the first set of coils. For at least a second portion of the stroke, the second core is within the second set of coils.
