High-integrity signal transmission is mission-critical in subsea operations, whether for HD video, radar, or telemetry. MacArtney’s new TrustLink™ Coax connector delivers this capability through precision impedance matching in a compact, rugged design that ensures stable, low-loss connections for demanding environments.

The TrustLink Coax connector combines low-attenuation signal transfer up to 4 GHz with a pressure-rated shell tested to 600 bar for long-term reliability. Available in stainless steel or titanium, it offers a service life of up to 25 years. Titanium provides inherent corrosion resistance, while stainless steel can be paired with cathodic protection, giving operators flexibility to match material choice to operational demands.

For offshore energy, oceanographic research, naval systems, or subsea robotics, TrustLink gives operators confidence in signal integrity and material resilience for decades of subsea deployment.

Compact Integration for Streamlined Design

Beyond performance, TrustLink Coax simplifies system integration by combining coaxial signal and power in a single terminated assembly. This reduces penetrators and interfaces, saving space and easing the system designers’ work with tight configurations.

Delivered exclusively as a MacArtney-terminated assembly, it offers assured quality and deployment-ready reliability for global operations.

Built Around Customer Needs

“We have seen growing demand for robust, secure, impedance-matched coax solutions that do not compromise on size or durability. TrustLink Coax integrates seamlessly into tight configurations and supports both signal and power to depths of up to 6,000 meters. It is designed to meet the operational realities our customers face from seabed to surface,” said Paul Anthony, Global Business Manager Connectivity at MacArtney.

Strengthening the Subsea Connectivity Portfolio

TrustLink Coax builds on the original TrustLink Metal Shell design, complementing the proven SubConn® Coax range and working alongside TrustLink, SubConn, and OptoLink™ solutions. Together, this strengthened portfolio gives operators and system designers a broader choice of secure, high-integrity connectivity options for complex subsea applications.

Launching globally on 29 January 2026, the TrustLink Coax range will be available through MacArtney’s international operations and preferred distributors. For details or to discuss integration options, contact your local MacArtney representative.

Engineered with purpose and built for performance, TrustLink Coax delivers secure, high-integrity connectivity in a compact, pressure-rated assembly. Fully terminated and deployment-ready, it simplifies system integration and ensures long-term reliability for offshore energy, oceanographic research, naval systems, and subsea robotics.
