Application
These PE-insulated data cables with twisted pairs are used in particular for the interference-free transmission of data and signals over longer
distances. The high transmission rates are particularly suitable for RS 422 and RS 485 interfaces. These cables are suitable for fixed installations
as well as for flexing applications, for free movement without forced motion and without tensile stress, in dry and moist environments. Yv
black with reinforced outer sheath, is suitable for installation in the ground and in open air.
EMC = Electromagnetic compatibillity
CE = The product is conformed with the EC Low-Voltage Directive 2006/95/EG.
