摘要

The sensor arrangement (12) for sensing an approximation on an object and/or for sensing a fly-by on the object from ferromagnetic material, comprises two sensor coils axially extending with one another and turned together in row. The winding sense (14, 16) of the sensor coils (S1, S2) is opposite to the winding sense of another sensor coils. The sensor coils possess same coil parameters and same number of turns.
