3.1.4 PROFINET Cables
PROFINET cables used are based electrically on category 5 balanced LAN cables according to ISO/IEC 11801 Edition 2.0, Class
D.
Type C cables can be used in special applications (for example, the use of trailing cables and frequently moved machine
parts) even though their design and mechanical parameters can deviate from the specifications of type A and type B cables.
Still, most of the electrical parameters (e.g. impedance levels) are retained. Highly flexible copper cables generally have the
finest stranded conductors and, for example, a highly resistant polyurethane outer sheath.
Various outer sheath materials are permitted to meet the various demands regarding resistance of industrial environments
and exterior/underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low temper-
atures, UV radiation, etc.).
