High-performance data transmission solutions

chainflex® data cables ensure reliable data transmission in continuous motion, making them ideal for moving applications in industrial systems and machinery. Typically shielded, they carry a wide range of signals, including standard 0–10 V and 4–20 mA.

Designed for permanent movement in energy chains, often alongside bus and control cables, they offer high flexibility and durability. This enables a long, predictable service life, which can be accurately calculated using our service life calculator based on your specific application conditions.

Data cables structure

Our data cables are available in various mechanical classes and three electrical designs, tailored to meet specific transmission requirements. To ensure reliable performance, we use twisted pair construction and optional pair shielding to maintain key electrotechnical parameters.

Twisted pairs reduce crosstalk and minimise interference from electrical and magnetic fields, as disturbances largely cancel each other out. For higher protection, cables with individually shielded pairs provide additional defence against electromagnetic interference between cores.

Applications with chainflex® cables

University project 'e-kart' is supported by igus products

A team of students at Karlsruhe University of Applied Sciences set themselves the goal of converting a kart with an internal combustion engine and road approval into an 'e-kart' that provides maximum driving pleasure. For years, the electric kart has been undergoing optimisation and conversion at the hands of the students. Until recently, a new fast-charge battery was integrated, and many of our products were also used. Among other things, shielded cables that withstand the high speeds and accelerations.

Limited space? We have the solution!

A system that has to work around the clock under high pressure requires the highest standards - also from the suppliers of the individual components of the machine. An example of this would be the "Speedmounter" system from IPTE GmbH. By using our energy chains and chainflex data cables maintenance intervals have been reduced and the company can save considerable costs. In addition, our cables attract with their special design, with gusset-filled extruded inner jacket, they retain their transmission properties after many millions of double cycles.

Frequently asked questions regarding data cables

An SY cable is used for applications where mechanical protection is required.

igus® does not produce SY cables, why? SY stands for steel wire braided, and the galvanised steel wire braid are not designed to withstand repeated bending or flexing as the steel braid can fracture or unravel over time.

Alternatively, we offer our e-chains® as mechanical protection. igus® also provide CY and YY cables.
