Abstract: A position detecting device for detecting a positional relationship between a first component and a second component includes a marking arrangement which is provided on the first component and has an absolute track and an incremental track. The absolute track has a plurality of absolute markings from which a binary absolute code sequence can be read, and the incremental track has a plurality of incremental markings which are associated with the absolute markings and from which an alternating incremental sequence can be read. A sensor arrangement provided on the second component and is configured to scan the absolute markings and the incremental markings. The absolute code sequence is formed from a first and a second De Bruijn sequence of order N which follow one another.

Abstract: The present invention provides a position detecting device for detecting a positional relationship between a first component (10) and a second component (12), comprising a marking arrangement (14) which is provided on the first component (10) and has an absolute track (18) and an incremental track (20), the absolute track (18) having a plurality of absolute markings (22) from which a binary absolute code sequence (B) can be read, and the incremental track (20) having a plurality of incremental markings (24) which are associated with the absolute markings (22) and from which an alternating incremental sequence (I) can be read, and a sensor arrangement (16) which is provided on the second component (12) and is configured to scan the absolute markings (22) and the incremental markings (24; 24), wherein the absolute code sequence (B) is formed from a first and a second De Bruijn sequence (B1, B2) of order N which follow one another, the second De Bruijn sequence (B2) being a cyclic shift of the first De Bruijn se
