The Challenge
A robotics manufacturer needed cable assemblies for 6-axis robot arms where continuous motion, tight routing, shielding, and strain relief all had to be controlled before production release.
Key Pain Points:
- 1Continuous flexing at robot joints and cable carriers
- 2Mixed power and signal routing in a compact cable package
- 3Shielding and grounding requirements for encoder and sensor signals
- 4Need for documented assembly and electrical test records
Requirements:
- Flexible cable construction suited to the customer's bend-radius requirement
- Mixed signal + power in single cable package
- -20°C to +80°C operating temperature
- EMI shielding for sensitive encoder signals
Our Solution
We supported the customer with high-flex cable assembly design input, material and construction review, and validation planning for continuous-motion use.
Custom Conductor Design
We reviewed conductor, stranding, and lay options for continuous flexing applications so the released assembly matched the customer's motion profile.
Proprietary Jacket Materials
We helped select jacket and insulation options appropriate for flexibility, abrasion resistance, and routing through cable carriers and robot-arm channels.
In-House Flex Life Testing
Validation support can include continuity, insulation resistance, hipot where required, and customer-defined flex-life test documentation before production.
Optimized Cable Construction
Neutral axis positioning ensures power conductors, signal pairs, and shielding all flex uniformly without differential stress. Elements are arranged to minimize internal friction during continuous motion.
