Abstract. The current problems and limitations associated with improving the accuracy parameters, resolution, reliability indica-tors, 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 im-provement of the main parameters of the rotation angle sensors are systematized, and a conclusion on possible direc-tions of reducing their impact to improve the characteristics of the converters is given.
Keywords: photoelectric digital angle converter, encoder, angular position sensor, angle-code converter, accuracy, reliability, reso-lution
