Cable & Harness

What you don’t see is sometimes what protects you the most.

Interconnectivity is where cable and harness play main roles of defense. Without this interconnectivity, we leave military vehicles and fleets at the risk of paralysis. Just like our central nervous system, cables and harnesses are what allow for effective communication.

So while you may not see the miles of cabling under that seat or dashboard, rest assured that this protects against multiple system interference, EMI (electromagnetic interference) and electronic warfare through EMI shielding.

TerraNova specializes in multiple cable types, including: ground straps, power, ELAN, CNR, and interconnect cables, to name a few. Complexity levels run from high, to medium, to low, but our team prides itself on low volume / high mix, which often means high complexity.

TerraNova provides defense sectors with ISO 9001 certified custom cable assembly and Mil-Spec cable design. See our other Cable and Harness Certifications.

Our multidisciplinary team ensures the use of conductors and shielding is ruggedized to function optimally, in even the harshest environments. Our build-to-print single and multi-branch wire harnesses offer turn-key solutions, regardless of the terrain. Trust the invisible to make your operations invincible.
