How can chain-compatible cables extend service intervals?

Beke Nieszytka | 1. October 2019

At some point, you have certainly had to deal with a loose contact. It may have been at home when you were ironing clothes or using your drill.

Fun fact:
A loose contact is a point that causes the transfer resistance within the circuit to fluctuate greatly or causes unintentional circuit interruption from time to time. A loose contact can be due to loose plug-in connectors or manufacturing defects (such as cold solder joints).

If the defective electrical connection occurs in an industrial process, a negative spiral can develop very quickly. The focus is on reducing machine downtime due to servicing, set-up or failure and on increasing production output. If a fault occurs in a production chain and planned production steps cannot be completed, productivity is affected in a very short time.

Cables – flexible or suitable for drag chains?

Modern machines often have flexible cables in accordance with a relevant DIN standard, such as DIN VDE0298-4, DIN VDE0207, DIN VDE0281-1 or DIN VDE0281-2. However, the various standards say nothing about the purpose of use in an energy chain. Manufacturing rate increases, accelerated travel speed, and constricted installation spaces quickly challenge these cables to their limits, and they are unable to meet requirements. In these cases, special cables that have been designed to meet demanding bending, torsion, abrasion, chemical resistance, or welding spark requirements, offer a solution.

Many of these cables, such as torsion-resistant cables for robots, chain-compatible cables for linear movements, or cables for hanging applications where the cable’s dead weight influences its structure are particularly suitable for special applications. Here, no distinction is made between shielded and unshielded control, power, or bus cables.

Fibre optic cables (FOC), can also be adapted to the purpose for which they are being used. Special cable design enables you to avoid typical faults such as cable breakage, corkscrews, wire breakage, EMC problems (shield wire breakages), and jacket abrasion, extending your service intervals.


“Special cables? That sounds complicated and expensive and certainly means a long delivery time.”


Wrong on all three counts.
