Abstract: For industries and robot applications the transducers of angular and linear positions with pseudo-random encoders are used. A possible improvement in this feature is the use of two pseudo-random code heads which is now employed. We found during testing that it is easy for practical work and bring improved performance, redundancy and reliability. In the proposed encoder solution, the checking methods of pseudo-random code can ensure reliable position.
