Advanced Interconnect Solutions Powering the Next Era of Aerospace

In the aerospace industry, every gram counts. Reducing weight is not just about improving fuel efficiency—it directly impacts payload capacity, operational range, and environmental performance. As aircraft and spacecraft systems become more complex, the demand for lighter, more compact components has never been greater. Radiall, a global leader in interconnect solutions, is meeting this challenge head-on with innovative designs that deliver high performance while significantly reducing weight across critical aerospace applications.

Radiall’s EPX™ series exemplifies how modular design and lightweight construction can come together to optimize aerospace efficiency. Designed to meet EN4644 standards, these rectangular connectors are ideal for use in aircraft panels, galleys and line-replaceable modules. A standout feature is the new one-piece connector shell, which is 30% lighter and simplifies installation by reducing the number of parts required. The EPX™ series also supports high-density configurations and right-angle contacts, making it a flexible, space-saving solution for modern avionics architecture.

For in-cabin applications where space and weight are at a premium, Radiall’s QuickFusio™ hybrid connectors provide a compact, high-performance solution. Weighing just 20 grams per pair, these connectors integrate up to 23 electrical and 24 optical channels in a single compact format. By utilizing standard SAE-AS38999 contacts, they ensure compatibility while offering weight and cable complexity reductions across systems such as lighting, IFE and seat electronics. Complementing this is the D-Lightsys® transceiver range, which delivers up to 12 optical channels at 10+ Gbps in an ultra-miniature, low-power package, ideal for demanding aerospace environments.

Radiall’s LuxCis® (ARINC 801) and Q-MTitan (ARINC 846) connectors are purpose-built for extreme aerospace environments, offering reliable performance across a broad temperature range from -55 °C to +125 °C. These fiber-optic solutions are widely used in both commercial and military aviation for their ability to maintain signal integrity under shock, vibration and EMI exposure. By leveraging miniaturized, ruggedized transceivers and optical harnesses, Radiall helps aircraft designers reduce overall cable weight while improving system reliability. These connectors are particularly valuable in fly-by-light and high-data-rate applications where traditional copper solutions fall short.

To address the stringent demands of space and military applications, Radiall has introduced lightweight versions of its SMA and TNC coaxial connectors made from aluminum and titanium. These redesigned connectors are up to 50% lighter than their stainless-steel counterparts, offering significant mass savings without sacrificing mechanical or electrical performance. The TNC self-locking feature adds further value by simplifying installation, saving time and removing an additional inspection step. Engineered for satellite systems and avionics, they maintain robust durability under extreme thermal and mechanical stress. This weight reduction directly contributes to lower launch costs and improved system efficiency in spaceborne and airborne platforms.

As the aerospace sector expands into Advanced Air Mobility (AAM), including urban air vehicles and electric vertical takeoff and landing (eVTOL) platforms, Radiall is at the forefront with interconnect solutions tailored for these next-generation aircraft. Their compact fiber-optic and RF connectors are designed to support electric propulsion, autonomous systems and advanced avionics within the tight weight and space constraints of AAM designs. Products like the QM and QuickFusio™ series offer rugged performance, ease of integration and the lightweight characteristics essential for enabling reliable and efficient flight in this rapidly evolving field. Radiall’s AS9100-certified components ensure compliance with strict aerospace standards while meeting the dynamic needs of emerging mobility platforms.

Radiall’s lightweight solutions are engineered to deliver exceptional performance under the harshest aerospace conditions. Their components are built to withstand extreme temperatures (from -55 °C to +125 °C), resist electromagnetic interference (EMI), and endure high levels of shock and vibration—crucial for both in-flight and space environments. Features like immersion resistance at altitudes up to 50,000 feet and 50 g shock tolerance ensure system integrity in critical applications. They feature immersion resistance up to 50,000 feet and can withstand shocks of 50 g, ensuring system integrity in the most demanding aerospace applications. Whether in satellites, commercial jets or AAM vehicles, Radiall’s designs offer consistent mechanical and electrical reliability while significantly reducing system mass and complexity.

Radiall is helping shape the future of aerospace by creating lighter, more efficient products. From compact connectors all the way to fiber optic solutions, these smart designs both bring down the weight but elevate the overall performance. As the industry leans towards faster, environmentally friendly and flexible technologies, Radiall continues to be a reliable partner making progress possible.
