Abstract:
A position-measuring device includes a code, including a series of code elements arranged one behind the other in a measuring direction, in which at least two consecutive code elements respectively form a code word containing a position information item, and a scanning device having detector elements for reading the at least two code elements of the code that form a code word, and an evaluation device in which the code word having the current position information may be ascertained from the scanning signals of the detector elements. The scanning device and the code are arranged in a moveable manner relative to each other in the measuring direction. Between adjacent code elements, which have identical properties in the transition region, separating elements having complementary properties are inserted.
