Introducing EIS’s New Line of Continuous Flex Control Cables

For use with Robotic Arms & Automation Equipment

Original Press Release Written By: EIS Wire & Cable

Lapp Tannehill knows there is a high demand for custom cables. By partnering with EIS Wire & Cable, we provide their custom cables that keep customers' vast range of applications at top of mind.

EIS Wire & Cable designs custom continuous flex cables for industrial applications where continuous motion and flexing is applicable to many of their customer's use cases.

Industries where these flex cables are used are Robotics, Automation, and Industrial where there is typically equipment that requires continuous movement.

EIS Wire & Cable has collected extensive data in their one year in-house testing. They've tested a variety of flex test methods and have validated their custom cables for use in continuous flex applications with specific ratings for even the most complex designs.

Lapp Tannehill proudly distributes EIS Wire & Cable custom cables which have a variety of jacket materials such as PVC, TPE, and TPU in both shielded and unshielded configurations.

These custom cables offer superior quality and optimum longevity of use - which maximizes your equipment’s up‐time and minimizes your maintenance costs.

Basic design configurations are offered in gauge sizes 24AWG – 18AWG with a minimum of 19 strands on the wire gauge selection. Also available in 300V and 600V rating and ‐30C to 105C temperature rating with agency approvals available for Tray cable, Communications, AWM in UL & CSA, as well as MSHA and PMSHA.

Flex Testing Protocol

The Automation Industry has recognized a series of test methodologies that ensure extended life expectancy in continuous motion industrial settings.

The flex test protocol commonly used for these types of cables include Bend Radius Test (Tic‐Tock) and Torsion Flex Test (Twist‐Bend). These test methods were designed to replicate the harsh mechanical stresses that cables would see in a robotic or motion application.

Cable designs that can withstand these rigorous test methods are deemed suitable for rolling flex (C‐Track), repetitive single point, and robotic applications.
