Due to torsion paired with horizontal linear movements, Ethernet cables have to withstand a lot when used in industrial robots. LAPP is now offering a solution: the new ETHERLINE® ROBOT PN Cat.5e complies with the new type R standard for PROFINET cables on robots.

The PROFINET user organization has now drawn up the necessary specifications in close consultation with AIDA (the Automation Initiative for German Motorists). LAPP has also been involved in developing the new industry standard from the very beginning. The new “type R” describes two-pair Cat.5e industrial data cables, which must withstand numerous electrical and mechanical requirements and provide longevity when used in industrial robots.
The mechanical requirements are enormous: A type R-compliant cable must be able to endure all of these tests before it is ranked as a robot-compliant cable according to PROFINET: 5 million vertical torsion cycles at ±180° per metre, 5 million cycles in the horizontal cable chain at accelerations of up to 10 m/s² and speeds of 3 m/s over a travel distance of 5 m, an additional 1 million bends in the alternating bending test according to EN 50396 at a bending radius of just 7x outer diameter.
LAPP, the global market leader for integrated cable and connection technology solutions, has developed the new ETHERLINE® ROBOT PN Cat.5e for this field. It is suitable for industrial data cabling within or on a robot and can be used in cable assemblies or laid freely. It offers a high load capacity, longevity and data communication reliability with data rates of up to 100 Mbit/s.
Thanks to the filling elements and reliable materials, such as the robust PUR outer sheath, the ETHERLINE® ROBOT PN Cat.5e not only covers the mechanical load requirements but also complies with important certifications and standards such as UL compliance as per AWM Recognized. This enables it to be exported as a component within a machine or system to the North American market.
The new ETHERLINE® ROBOT PN Cat.5e is manufactured in LAPP’s own competence centre for data cables at CEAM Cavi Speciali in Monselice, Italy. CEAM Cavi Speciali is one of the leading manufacturers of data cables for industrial Ethernet and fieldbus and has been part of the LAPP Group since October 2016.
