Abstract:
A coding head for applying magnetic codes onto magnetizable layers of scales, graduations, angle encoders, transport belts and the like has a magnetic pole (10) about which a coil (12) is wound, the saturation induction of the magnetic pole being selected in dependence upon the coercive field strength of the magnetizable layer (18). In this case, the saturation induction (in Tesla) has a specified relationship to the coercive field strength (in kOe).
