 Abstract
In this paper, the all- theoretical aspects of the new absolute encoder system (NAES) are shown. A succinct analyze offers the major advantages of the new linear encoder. In contrast with the classical binary linear encoder, the new solution presents a strong encoder ability, ideal for long distance applications (greater then 40m), a fine accuracy (0.5mm) and a very good reliability (the algorithm uses only 5 active tracks and 5 optical sensors). The practical application is the control of linear motors used in intelligent warehouses or factories.

 Rezumat
Lucrarea prezintă conceptele de bază utilizate la proiectarea şi executarea unui nou tip de encoder absolut dedicat poziţionării în cazul deplasărilor pe distanţe mari (peste 40m) şi acurateţe fină (0.5mm). Sistemul se bazează pe o dublă codificare: una de tip binar şi alta de tip codificare numerică a distanţei. Sistemul de codare propus obţine performanţele cerute cu un număr minim de senzori optici şi o riglă specială de codare. Prin optimizarea propusă, din cei 3 traductori optici doar unul este de performanţă ridicată, respectiv cel care citeşte pista de rezoluţie fină. In plus, se realizează şi bune performanţe de viteză, echipamentul satisfăcând condiţiile impuse sistemului inteligent de poziţionare.
