Encoders excel at angular accuracy
A
Heidenhain (GB) product story
Edited by the Engineeringtalk editorial team
Oct 21, 2003
A new range of absolute angle encoders feature a system accuracy of +/-1arc-sec.
A new range of absolute angle encoders feature a system accuracy of +/-1arc-sec.
This higher accuracy has been made possible by advancements in bearings and the optimisation of the scanning process with signal enhancement.
Three new versions of Heidenhain's RCN series are available: the RCN 827 has Heidenhain's EnDat interface; the RCN 823 has a Fanuc interface; and the RCN 823 has a Mitsubishi interface.
Because of their dynamic accuracy, these encoders with their integral bearing and stator coupling are the preferred units for high-precision applications such as rotary tables and swivel heads on machine tools, telescopes or spectrometers.
These RCN encoders can be designed with one scanning unit on the main track (with 32,768 grating periods) and therefore fulfil all requirements of machine tool design and except for the higher accuracy, have the same specifications as the RCN 727 and RCN 723.
They all have a hollow through shaft and a diameter of 60mm.
