Figure 11-8 Max. cable length as a function of the current drawn by the encoder system
In addition to the encoder systems for a supply voltage range of 4.75 V to 5.25 V in the figure
above, encoder systems are also available for an extended range down to 3.6 V.
These can be generally operated using encoder system cables up to 10 m long provided that
the total cross-section of the supply core plus Remote Sense cores does not fall below
0.14 mm².
