AR90
Ø90mm absolute encoder
This is a high-resolution, singleturn absolute encoder with a 22 Bit BiSS-C interface. The encoder consists of several optical reflectance sensors arranged at an angle of 180 degrees to each other. This allows to eliminate mechanical errors in the application, such as the runout of the measured shaft, by using subsequent electronics.
