Abstract
An inductive sensor device includes a scale unit () containing field elements () that cooperate with a transmit circuit () to create a field pattern (S(x)) in measuring direction (M). A sensor unit () contains at least one receive circuit () with at least one receive coil (), respectively. The sensor unit () and the scale unit () can move relatively in measuring direction (M). The coil loops () of the at least one receive coil () and/or the scale loops () of the scale elements () are separated into a loop front () and a loop back (), each containing a sectional portion that runs alternately with regard to the height direction. The alternating run can be obtained by combining linear and/or curved portions so that a meandering, zigzag, sinusoidal, or another arbitrary alternating run can be obtained.
