According to the application two different forms can be used.
a.) magnetic strips for length measuring systems of short distances up to approximately 100mm
[flexible plastic material filled with magnetic north-south-parts in a defined raster , for example thickness 1,5mm and width 5mm and magnet
pole length 2mm with transverse unilateral magnetization , separably from magnetized foils of the company Max Baermann GmbH ,
