Abstract: The invention relates to an optoelectronic position detection system for position determination having a positioning scale with position marks and a sensor apparatus with two sensor units each consisting of a light receiver for generating received signals from received light that was reflected by the position marks and each having an evaluation unit for evaluating the received signals and outputting the evaluation results. To provide a position detection system that works more robustly and more reliably and that in particular satisfies the functional safety such as is demanded by the relevant safety standards, it is proposed that the sensor units are configured as identical. The invention further relates to a method for failsafe position determination in which position marks on a positioning scale are detected by an optoelectronic position detection system.
