What is described is a configuration for determining the position of a body along a movement direction, wherein the body is in the form of a magnetized encoder with two magnetic tracks extending, on one surface of the body, along the movement direction, at least essentially in parallel with one another, wherein, at specified intervals along the movement direction, a first of the magnetic tracks exhibits magnetized sections in which the magnetic north poles are aligned so as to be at least largely coincident in a magnetization direction that is essentially at right-angles to the surface of the body, and wherein, at intervals specified to coincide with the above-mentioned intervals along the movement coordinate, the second of the magnetic tracks exhibits magnetized sections in which the magnetic south poles are aligned so as to be at least largely coincident in the said magnetization direction, and wherein, in each case, a magnetized section of one of the magnetic tracks is located at least largely centrally in relation to a gap between two magnetized sections of the other magnetic track, with a magnetoresistive sensor, in the form of an angle sensor, which is arranged above the magnetic tracks, for determining the directions of magnetic fields brought about by the magnetized sections of the magnetic tracks in an area extending along the movement coordinate, essentially in parallel with the surface of the body. By virtue of the invention, a simple configuration for the precise determination of the position of a body along a movement direction is created, wherein this configuration does not necessarily have to be affixed centrally upstream of the head of the body.
(ZH) 本发明披露了一种用于确定本体沿着运动坐标的位置的结构，其中所述本体呈已磁化的编码器的形式，在本体的一个表面上具有沿着运动方向延伸的两个磁轨迹，它们至少基本上彼此平行，其中，沿着运动方向以特定的间隔，第一个磁轨迹具有这样的已磁化的部分，其中磁北极被对准以便至少在磁化方向上很大程度上一致，所述磁化方向基本上和本体的表面呈直角；并且其中，以和上述的沿着运动坐标的间隔一致的特定间隔，第二个磁轨迹具有这样的已磁化的部分，其中磁南极被对准以便至少在所述磁化方向上很大程度上一致，并且其中，在每种情况下，其中一个磁轨迹的已磁化部分相对于在其它磁轨迹的两个已磁化部分之间的间隙至少基本上在中央设置，具有呈角度传感器的形式的磁阻传感器，其被设置在磁轨迹的上方，用于确定在沿着运动坐标延伸的区域内由磁轨迹的已磁化部分产生的磁场的方向，所述运动坐标基本上平行于本体的表面。利用本发明，形成一种简单的结构，用于精确地确定一个本体沿着运动方向的位置，其中这种结构不必被中心地固定在所述本体的头部的上游。
