Heidenhain is introducing an optimised design and new appearance for the RON and RCN absolute and incremental angle encoder series.
The encoders of this series are equipped with an integral bearing as well as an integral stator coupling.
The new sealing concept and the clearly recognisable outlet channels on the flange and rear side of the encoder ensure that fluids cannot collect on the encoder, or, in a worst-case scenario, seep inside the encoder housing.
The new integral stator coupling and the revised design of the angle encoders also contribute to the significant improvement of the dynamic rigidity.
The reduced weight and strict symmetric set up result in a substantial increase in the natural frequencies of the encoders.
The new signal processing electronics for the absolute angle encoders raise the resolution to up to 134 million position values (27 bits) per revolution, and permit the output of the absolute position even at highest speeds.
The term angle encoder is typically used to describe encoders with an accuracy of better than +/-5 arc-seconds and a line count above 18,000.
These encoders are found in rotary tables and swivel heads on machine tools, telescopes or spectrometers, as well as everywhere where accuracies within several arc seconds are required..
