<p>PURPOSE: A magnetism encoder element and a sensor device are provided to enable vertical magnetization on the main surface of a plastic strip including a permanent magnet. CONSTITUTION: A magnetism encoder element comprises a first magnetic track(15). The first magnetic track has material which provides magnetic patterns along a first direction. The magnetic pattern is formed by remanent magnetization vector. The remanent magnetization vector essentially points one direction and does not change the direction along the first direction. The magnetic patterns comprise a first segment and a second segment(11,12).</p> |
