Measuring graduation for a position measuring system

A measuring graduation for position measuring systems, comprising a base body formed of a permanently magnetizable material and extending in a measuring direction, the base body having first and second sections alternatingly arranged one after another in the measuring direction and having, respectively, first and second magnetization directions, a position information being generated by a sensor displaceable relative to the base body in the measuring direction for scanning same, wherein the second sections are formed by magnetically weak regions, and wherein the second magnetization direction of the second sections is defined by the first magnetization direction of adjacent first sections wherein the weak regions, viewed in the measuring direction, have a contraction in a middle region thereof.

A position measuring system, comprising:

• a measuring graduation having a permanently magnetized base body extending in a measuring direction, the base body having first and second sections alternating arranged one after another in the measuring direction and having, respectively, first and second magnetization directions, with the second sections being formed by magnetically weak regions and with the second magnetization direction of the second sections being defined by a magnetic reflux of the first magnetization direction of adjacent first sections;
• and
• at least one sensor displaceable along a longitudinal side of the base body in the measuring direction for scanning same for generating position information.
