Free white paper: Strain relief for cables in industrial applications
In automated machinery, cables face constant mechanical stress with every movement. That's why proper strain relief is critical — it helps secure cables within e-chains®, reducing wear and tear while improving safety, reliability, and system performance.
This free white paper explores the key strain relief technologies and explains how selecting the right solution can maximize efficiency and durability in demanding industrial and automation environments.
Minimum gap between the strain relief and the beginning of the bend radius
A series of in-house tests have shown that a small distance between the strain relief and the bend in the e-chain has no negative impact on the durability of chainflex cables. It is therefore possible to integrate a strain relief for cables directly into the mounting bracket. We offer strain relief options, such as the chainfix clamp or the space-saving tiewrap plates for almost all e-chains.
Frequently Asked Questions
Strain relief prevents tensile forces from acting uncontrollably on cable connections. This is particularly important in dynamic or heavily stressed applications to prevent damage such as cable breakage or vibrations and shocks.
The right strain relief offers several decisive advantages:
- Increased service life of the cables: reduction of mechanical stress and prevention of cable breaks
- Greater operational reliability: fewer breakdowns due to damaged cables
- Economic efficiency: fewer cable breaks and failures significantly reduce repair and maintenance costs
- Better performance: cables can work more trouble-free, even with long and intensive mechanical use
A cable feed-through with strain relief fixes the cable in the cable gland or in the plug-in connector. The strain relief ensures that external forces are not transferred to the cable and are instead absorbed by the structure on which the strain relief is assembled.
The forces at the contacts in the connector or in the cable are then zero. No matter how much the cable moves on the outside, it is at rest on the inside. This protects the contacts and sensitive electronics.
To ensure the optimum performance of energy chains, the following criteria should be taken into account:
- Cable type and diameter: Flexible cables require different fastenings than thick cables
- Movement profile of the energy chain: High speed or tight bend radius influence the requirements
- Environmental conditions: Temperature, humidity and chemical load must be considered
- Assembly requirements: Quick maintenance or modularity are often decisive
