New Motionline hybrid cables integrate multiple functions
Nexans has launched its high-tech hybrid cables that integrate individual power, data and signal transmission functions within a single cable. The new hybrid cables offer an innovative approach to the interconnection of automation equipment that provides a neat, space-saving installation that is both faster and easier than using individual cables for each function, as well as ensuring additional flexibility for future reconfiguration and expansion projects.
Nexans' new hybrid cables comprise a power cable as well as at least one other key automation application within a single cable cross-section. For example, the cable could comprise a power cable and one or more of the following applications: signal, bus, sensor, control and POF (plastic optical fibres) cables.
The traditional approach to the installation of automation equipment, such as servo motors or robots, is to use individual cables for each power, data and signal transmission connection between the control cabinet and the unit. This approach is time-consuming, and when there is a need to add additional units further cabling is necessary, and additional plugs and sockets may also need to be mounted on the cabinet. BUS-cables can reduce this cable work by offering easy connection of each active component. Now, with the introduction of hybrid cables, Nexans is taking the BUS-cable concept to the next level.
Replacing a typical "star' configuration, in which each automation unit is clustered around the control cabinet, with a de-centralised "loop' or "daisy-chain' configuration that connects the units to each other creates a simple system which is less time consuming in installation. It is also easy to expand, as the new unit is simply plugged into one of the existing units.
Due to the wide variety of potential applications, the hybrid cables are not available off the shelf. Nexans will provide a customised cable for every installation; however, every cable will comprise the following basic elements: data transmission; power conductors and a protective conductor; signalling elements. The cables are designed for protection against EMC (electromagnetic compatibility), and a TPU (thermoplastic polyurethane) sheath is recommended to ensure resistance against the various potentially damaging liquids and substances found in automation applications. Nexans has successfully developed and tested a hybrid cable capable of carrying 28A on each 4mm2 power core.
Choice of the optimum connector is crucial to the success of any hybrid cable installation. As part of its total systems approach, Nexans has partnered with Intercontec to develop a new generation of versatile hybrid connectors.
The Motionline brand
Nexans' Motionline brand cables comprise a range of products that has been developed specifically to deliver high-performance and total reliability in a wide variety of control chain, bus, sensor and robotic automation applications. The hybrid cables were developed at the Nexans MAC (Motion Application Centre) in Nuremberg and are manufactured at the factory on the same site.
