For a defined PROFIBUS cable reference, LAPP 2170220 identifies UNITRONIC BUS PB. The single twisted pair uses a published conductor diameter of 0.64 mm and the complete cable measures 8 mm outside. Selection of this PVC-sheathed article must account for the relationship between segment length and data rate.
Application selection
Verify the PROFIBUS segment length and the connector's accepted conductor diameter.

D is cable outer diameter. Published dimensions do not replace checks of current, motion and termination for the application.
Is the 0.64 mm value a conductor area?
No. It is a conductor diameter and must not be confused with cross-sectional area in mm².
