Flexible data cable as information carrier



Data cables

Differently structured data cables are used for the simple transmission of information in industrial plant and machines. The information is converted into voltage or current signals, which are often designed as 0 to 10 V or 4 to 20 mA signals.

chainflex data cable

Structure of a data cable made of PVC, PUR and TPE

 

igus GmbH manufactures a very wide range of data cables. These are available in different versions with PVC, PUR or TPE outer jacket and are available as simple data cables with cores wound in layers or as twisted pair (TP) cables. The latter are also offered with additional pair shielding for very high electromagnetic compatibility resistance. chainflex cables are available for almost any application from a length of 1m with no cutting charge. Data cables from igus are designed for a bend radius of up to 6.8 x d. We would like to briefly explain the differences and their areas of application to help you choose the right data cable for your application.

Shielded or unshielded data cable?

 

Data cables are often offered in unshielded or shielded versions. Often these are classically referred to as LiYY (PVC data cable without shield) and LiYCY (PVC data cable with overall shield). However, due to the frequently occuring interference-prone signals, it is particularly recommended to use shielded data cables in the energy chain where motor cables and data cables are often bundled together in tight spaces.

Data cables from igus - the right choice even under heavy loads


By using in very different outdoor conditions data cables must be protected against a variety of influences. chainflex data cables can be selected as a flame-retardant version and/or halogen-free version, depending on requirements. Depending on the jacket material, medium to high oil resistance is also possible.
 
All data cables from chainflex are tested in the igus test laboratory for extreme loads in energy chain systems with many millions of double strokes. This allows igus GmbH to offer a 36 month functional guarantee for their data cables.
 
The test parameters are high speeds, acceleration in different bend radii and travels. The rates are several million repetition cycles per cable. Thereby the bend radii go below the limit specified in the catalogue in order to guide the cables to the load limit. igus GmbH offers a service life calculator for all cable types on its website. The service life is determined by the data from the test laboratory. The standard products determined in this way are subject to the igus money back guarantee for premature cable failure.

Network cable - secure data transmission in local networks


Despite the advances in radio technology, network cables are still an indispensable part of network hardware because of the high and secure data transmission in terms of digitisation and Industry 4.0. There are several standard types of network cables, each designed for specific purposes. Depending on the physical layer, topology and size of the network, different types of cables such as coaxial cable, fibre optic cable and twisted pair cables are used for cabling.
 
The most widely used standard Ethernet, for Local Area Network (LAN), was developed by Xerox Corp. in the mid-1970s at the Palo Alto Research Centre in California. In 1979, DEC, Intel and Xerox jointly standardised the Ethernet system. The first specification, called the Ethernet Blue Book, was released in 1980. This standard set speeds of up to 10 Mbps and relied on a large coaxial backbone cable.

Twisted pair cable


Twisted pair cables are manufactured without shielding and with single or double shielding. U/UTP (Unscreened Unshielded Twisted Pair) cables are simple standard cables without shielding. The twisted pairs of cores are surrounded only by a plastic jacket. Due to the lack of shielding, the U/UTP cables should only be used for connections less than 10 metres long and should not be routed near power cables.
 
S/UTP (Screened Unshielded Twisted Pair) Ethernet cables are shielded by a copper braid or an aluminium foil between the core pairs and the plastic jacket. In so-called FTP cables (foiled twisted pair), the individual pairs of cores are shielded. S/UTP- and FTP cables are used for cabling short and medium distances over 10 metres.
 
Network cables with double shielding are referred to as S/STP (Screened Shielded Twisted Pair) or S/FTP (Screened Foiled Twisted Pair). With S/STP cables, the cores are individually shielded. With S/FTP cables, the cores are shielded in pairs. In addition, both cable types have an additional shielding between the cores and the outer plastic jacket. S/STP and S/FTP cables are suitable for distances greater than 25 metres due to the double shielding.

Cat.6 and Cat.7 categories of network cables


Ethernet network cables are divided into categories (Cat.) from Cat.3 to Cat.8, which specify the transmission rates of the cables. Cat.6 cables were originally developed to support Gigabit Ethernet. These cables contain a physical separator between the four pairs to reduce electromagnetic interference. Cat.6 network cables support speeds of up to 1 Gbps for lengths of up to 100 metres. 10 Gbps are technically possible for cable lengths of up to 55 metres. In 2009, the improved standard Cat.6a was introduced. The "a" in Cat.6a stands for "Augmented". Compared to standard Cat.6 cables, the 6a cables support higher transmission speeds over longer cable lengths. Category 6a cables are always shielded.
 
Cat.7 is a newer copper cable specification, supporting speeds of up to 10 Gbps with 600 megahertz clocking at a transmission distance of up to 100 metres. To achieve this, the cable has four individually shielded cable pairs and an additional shielding to protect the signals from electronic magnetic interference.
 
Due to the high data rates, when installing a Cat.7 network infrastructure all components used must have the Cat.7 certification. These include patch panels, patch cables, sockets and RJ-45 connectors. Failure to use components other than certified Cat.7 will degrade overall cabling performance. Today, Cat.7 network cables are commonly used in data centres for backbone connections between servers, network switches, and storage devices.
 
Depending on the cable design, Ethernet cables are referred to as cross-wired or crossover cables, patch cables, and straight-through cables. Patch cables and straight-through cables are two designations for standard cables in which the core pairs are parallel side by side. Cross-wired or crossover cables are cable types in which the core pairs are crossed. These cables are used when two computers are to be connected directly to each other. A special case is the so-called Y-cables with which a network cable can be split up for shared use by two computers or devices.

Coaxial cable


A coaxial cable conducts an electrical signal using an inner conductor, usually a solid copper wire surrounded by an insulating layer. The insulating layer is in turn surrounded by a shielding, which typically consists of one to four layers of a woven metal braid and metal strip. The cable as a whole is protected by an outer jacket. The advantage of the coaxial design is that electrical and magnetic fields are limited to the dielectric and only low losses occur outside the shield. Conversely, electrical and magnetic fields outside the cable are largely prevented from disturbing signals within the cable. These specifications make coaxial cables suitable for transmitting weak signals that cannot tolerate environmental interference or for stronger electrical signals that must not interfere with adjacent structures or circuits.
