HIGH-SPEED RUGGED INTERCONNECTS: WHY RELIABILITY IN EXTREME CONDITIONS STARTS HERE
Introduction: Performance Under Pressure
In aerospace, defense, and heavy industrial systems, failure is not an option. Whether it’s a fighter jet in midair, a combat vehicle navigating unpredictable terrain, or a robotic arm on a noisy factory floor, critical systems rely on interconnects that don’t just perform, they endure.
At Meritec, we understand what’s on the line. Our
Hercules® Interconnect System
was engineered specifically for these extreme environments. When speed, reliability, and durability must come together, Hercules delivers performance without compromise.
What Makes an Interconnect Rugged?
A rugged interconnect isn't simply defined by its physical toughness. It’s the fusion of mechanical strength, environmental sealing, and high-speed data integrity that sets these connectors apart. Hercules is built to excel in environments where shock, vibration, moisture, electromagnetic interference, and thermal extremes are daily realities.
Capable of transmitting over 10 Gb/s per differential pair, Hercules maintains performance in temperatures ranging from -65°C to +175°C. Shielding is integrated directly into the assembly, protecting the signal from electromagnetic interference (EMI) and ensuring clear, reliable data transfer even in electrically noisy environments.
This kind of performance isn’t optional for systems operating in avionics, field-deployed command units, offshore rigs, or autonomous vehicles, it’s essential.
Inside Hercules®: A Solution Engineered to Last
The Hercules Interconnect System integrates Meritec’s high-speed connector technology into the proven MIL-DTL-38999 Series III circular shell. This military-grade housing is trusted by engineers around the world for its ruggedness and long service life.
But Hercules goes further, it is the approved ANSI VITA 76.0 (high-performance cable) standard.
Its design supports modern digital protocols, USB 3.0, PCIe Gen2, SATA, 10G Ethernet, and HDMI, with precisely engineered low-skew differential pairs for data consistency. When mated or capped, Hercules assemblies achieve an IP-67 environmental rating, protecting the system from dust and water ingress. The shell options include jam-nut or flange mounts, straight or right-angle orientations, and a range of sizes to support different space and performance needs.
This is not a one-size-fits-all solution. Hercules is engineered to be adapted, electrically, mechanically, and environmentally, to your unique system.
How Hercules® Performs in the Field
Across industries, Hercules has proven itself in systems where failure would be unacceptable.
In aerospace, Hercules supports onboard communication and sensor networks where connectors are exposed to high-frequency vibration, pressure changes, and EMI from surrounding systems. Its lightweight construction and sealing make it ideal for cockpits, avionics bays, and fuselage integration.
In defense, it’s trusted for use in vehicles and tactical systems. One ground-based mobile communications unit integrated Hercules to replace bulkier legacy connections. The result was not only a weight reduction but improved speed, easier servicing in the field, and no performance degradation under vibration stress.
For industrial and robotic systems, Hercules thrives in environments full of motion and noise. Automated arms, guided vehicles, and surveillance units benefit from its compact profile, flexibility, and data stability in the presence of continuous EMI.
And in
energy and transportation, Hercules holds up against salt, dust, and extreme weather, especially in systems like rail control, wind turbines, and subsea drilling infrastructure.
Built with Engineers in Mind
We believe high-performance hardware should never be hard to integrate. That’s why Hercules is designed not only for reliability, but also for engineering flexibility.
Available in multiple sizes and D-subminiature style shells, the system supports different insert arrangements and pin counts. It can be configured for power, signal, or hybrid layouts. Cable jackets and shielding options can be matched to suit your environmental and EMI requirements. Overmolding and mechanical strain relief are available to meet routing and flexure demands.
More importantly, our team doesn’t just hand you a catalog, we work with you to design what you need. From initial prototypes to field-deployable production runs, we offer responsive support and practical design collaboration.
Signal Integrity and System Compliance
In high-speed systems, clean data transmission is critical. That’s why Hercules is designed with a focus on signal integrity, not just rugged hardware.
Every cable assembly uses impedance-matched differential pairs and is built under tight tolerance for skew and crosstalk. This keeps your signals clean, even over longer runs, supporting real-time decision-making and high-bandwidth throughput. VITA 76.0 names Hercules as the standard to support a bandwidth greater than 10 Gb/s while also meeting the necessary signal density emerging in the ruggedized embedded systems.
All Hercules products are proudly manufactured in the USA using only qualified components and are tested to meet or exceed standards like IPC/WHMA-A-620 and MIL-STD shock/vibration testing. Our in-house testing process includes:
- Electrical impedance and continuity validation
- Environmental stress testing for temperature cycling and humidity
- Sealing performance under IP-67 guidelines
- Mechanical inspections for durability and build quality
