A steering rod for a steer-by-wire steering system is disclosed. The steering rod is designed to move in the axial direction over a distance S. The steering rod includes a first target lane with first conductive segments. Gaps exist between the first segments such that the first segments and gaps form a first pattern along the first target lane which repeats itself with a first period length p.sub.1.
