HYBRID POWER AND DATA CABLE ASSEMBLIES FOR MILITARY VEHICLES

Modern military vehicles require more than just rugged armor and tactical design. As onboard electronics become more advanced integrating AI-driven systems, real-time communications, and automated control units the demand for robust, compact, and efficient interconnects has surged. One critical solution enabling this evolution is the hybrid power and data cable assembly.

These assemblies combine electrical power conductors and high-speed signal lines within a single unified cable structure. In environments where space, weight, and reliability are at a premium, hybrid cable assemblies offer a high-performance alternative to separate cabling systems. Meritec has engineered ruggedized hybrid interconnect solutions tailored to the specific needs of military ground vehicles, armored platforms, unmanned systems, and mobile command units.

Why Hybrid Assemblies Are Mission-Critical

Military vehicles operate in some of the harshest and most unpredictable environments on Earth. These platforms are subject to intense vibration, electromagnetic interference (EMI), extreme temperatures, and exposure to water, mud, and fuel. Any failure in the power or data transmission path could compromise situational awareness, navigation, targeting, or communications.

Hybrid cable assemblies reduce these risks by offering:

• Fewer points of failure – A unified cable limits potential disconnection or degradation points.
• Improved routing – Reduced cable volume simplifies routing within tight enclosures.
• Lower weight – Combining power and signal lines can significantly reduce total harness weight.
• Enhanced shielding – Hybrid cables are easier to fully shield against EMI.

Meritec’s hybrid assemblies are custom-built to meet military standards such as MIL-DTL-38999 and are fully tested for resistance to shock, thermal cycling, salt fog, and mechanical fatigue.

Applications in Tactical Ground Vehicles

From infantry fighting vehicles to main battle tanks, modern armored platforms are loaded with electronics. Power delivery must be stable and uninterrupted, while high-speed data must transmit without latency or signal loss.

Hybrid assemblies support a wide range of critical onboard systems such as:



• Weapon control and stabilization
• Engine and transmission systems
• Imaging and sensor payloads
• Navigation and guidance systems
• Communications, including RF and SATCOM
• Vehicle diagnostics and health monitoring

By delivering clean power and secure signal within a single conduit, Meritec's hybrid solutions support faster deployment, modular upgrades, and lower maintenance risk.

Design Considerations for Harsh Environments

Designing hybrid assemblies for military vehicles goes far beyond simply combining power and signal conductors. Meritec engineers each interconnect to meet both electrical performance and mechanical survivability targets.

Key considerations include:

• Conductor specifications for both power and signal integrity
• Impedance control for differential data pairs
• Shielding strategies to ensure EMI/RFI compliance
• Overmolding and strain reliefs to maintain durability under repeated flex and shock
• Connector compatibility with MIL-spec and NATO standards

These assemblies are also subjected to finite element analysis (FEA), environmental simulation, and accelerated lifecycle testing to validate real-world performance.

Custom Engineering for Tactical Edge Systems

Meritec’s hybrid assemblies are not off-the-shelf solutions they are custom-engineered to meet the unique requirements of each platform. Whether supporting new ground vehicle designs or retrofitting legacy fleets, Meritec provides:

• Selection of high-performance conductor materials and shielding layouts
• Integration of rugged circular or rectangular MIL-spec connectors
• Overmolding designed for moisture protection and strain relief
• Solutions that support strict Size, Weight, and Power (SWaP) constraints

With vertically integrated manufacturing, Meritec offers short lead times, rapid prototyping, and reliable scaling critical factors for military programs with shifting operational timelines.

Testing & Validation Standards

Every hybrid cable assembly from Meritec is subjected to comprehensive quality and environmental testing, including:

• Thermal cycling from -55°C to +125°C (or higher, per spec)
• Ingress Protection (IP67/IP68) for water and dust sealing
• EMI testing using MIL-STD-461 methodology
• Mechanical shock and vibration per MIL-STD-810
• High-voltage dielectric and continuity testing

These rigorous validations ensure Meritec interconnects function reliably in combat-ready environments.
