Combining power supply and encoder signal in a single-cable

igus has developed a robust and reliable single-cable for servo motors. With an integrated bus element, the chainflex CF270.UL.D hybrid cable avoids the need for secondary signal cables.

Whereas in the past, servo motors and converters were generally connected with two cables – one servo cable for the motor’s energy supply and an encoder cable for data feedback – more and more drive manufacturers are now offering servo motors with single-cable technology.

This means that energy supply as well as data feedback are facilitated via a single cable, with complex measuring system cables being replaced by bus technology.

Specifically designed by igus for use in energy chains, the hybrid servo cable is guaranteed for millions of cycles at a bend radius of just 10x cable diameter. UL, CSA and NFPA79.2012 certified, the cable is oil resistant, flame-retardant and halogen-free.

In addition, thanks to its Desina conforming orange outer jacket, it is able to endure excessive load conditions, meeting the requirements of machining centres and machine tools, as well as conveyors.
