Cables in energy chains or connected to robots require special characteristics to function perfectly over long periods of time in spite of many movement cycles, high speeds, high rates of acceleration and challenging ambient conditions. In energy chains, cables must usually deal with just linear movements; in robotic applications, however, they also have to cope with torsional or twisting movements in order to follow the robot’s movement.

Motion plastics specialist, igus® has introduced its CFROBOT chainflex® cables featuring a special design to address these demanding torsional applications. Now available in variants from CAT5e to CAT7 for the highest data transfer rates, the cables are also shielded, resistant to oil and coolant, flame-retardant, and hydrolyse- and microbe-resistant.

All chainflex® cables have been tested extensively for durability in the igus® test lab in Cologne, the world’s largest test facility for moving cables, executing more than 2 billion test cycles per year. From the highest levels of mechanical operation data accumulated over millions of cycles, igus® can provide you with detailed information on the expected service life of your cable in its application and the reassurance of a 36-month guarantee.
