How to Install
3.1.3 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 (e.g. 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 (impedance levels etc.) 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 in order to meet the various demands with regard to resistance of industrial
environments and exterior/underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low
temperatures, UV radiation).
All balanced cables used shall comply with the following parameters:
