Систематизируются степень влияния и причинно-следственные взаимоотношения факторов, препятствующих улучшению основных параметров датчиков угла поворота, а также дается заключение о возможных направлениях снижения их воздействия в целях улучшения характеристик преобразователей.</p></abstract><trans-abstract xml:lang="en"><p>The current problems and limitations associated with improving the accuracy parameters, resolution, reliability indicators, as well as reducing the mass and size characteristics of photoelectric digital angle converters in products with a high degree of reliability, are analyzed. The degree of influence and causal relationships of factors preventing the improvement of the main parameters of the rotation angle sensors are systematized, and a conclusion on possible directions of reducing their impact to improve the characteristics of the converters is given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотоэлектрический цифровой преобразователь угла</kwd><kwd>энкодер</kwd><kwd>датчик углового положения</kwd><kwd>преобразователь угол-код</kwd><kwd>точность</kwd><kwd>надежность</kwd><kwd>разрешающая способность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photoelectric digital angle converter</kwd><kwd>encoder</kwd><kwd>angular position sensor</kwd><kwd>angle-code converter</kwd><kwd>accuracy</kwd><kwd>reliability</kwd><kwd>resolution</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Домрачев В.
