Abstract

An absolute position-measuring device includes a first subassembly having a measuring standard on which at least one code track is disposed, and a scanning unit with which, by scanning the at least one code track in a measuring direction, position signals are able to be produced, from which an absolute digital position value is able to be generated. The position-measuring device includes a second subassembly having at least one peripheral unit adapted to perform an additional or auxiliary function of the position-measuring device. The first subassembly and the second subassembly are connected to each other by a plurality of electric lines for the transmission of electrical signals. The first subassembly exclusively includes components which are suitable for use in a radiation area of a machine.
