Top Custom Cable Trends in 2024

The custom cable industry continues to evolve rapidly. Here are the trends shaping cable and harness design in 2024.

1. USB4 and Thunderbolt Adoption

With 40Gbps data rates and 240W power delivery, USB4 cables demand tighter impedance control and higher-quality shielding than previous generations. Certified e-marker chips are now standard in high-power designs.

2. High-Power EV Charging

Electric vehicle growth is driving demand for liquid-cooled charging cables and 800V-rated harness systems, with new requirements for thermal monitoring conductors integrated into the bundle.

3. Miniaturization

Wearables and compact IoT devices are pushing micro-coax and 36-40 AWG assemblies into the mainstream, requiring specialized crimping and inspection equipment.

4. Sustainable Materials

Halogen-free, recyclable jacket compounds and bio-based insulation materials are moving from niche to standard as OEMs pursue sustainability targets.

5. Digital Quoting and DFM Automation

AI-assisted quoting platforms now parse CAD drawings directly, returning manufacturability feedback and pricing in minutes instead of days — exactly what we built Harness Cart to do.

Conclusion

Staying ahead of these trends helps engineers design cables that are faster to source, cheaper to build, and ready for next-generation applications.
