Cable Assemblies Are at the Heart of Avionics, Aerospace Applications

Posted in: Cable Assemblies

The humble cable assembly might not be the first thing that comes to mind when someone thinks about aerospace or aviation. And yet such products are critical to the success of communications and control systems used in commercial and military aircraft and satellites.

Over the past 40 years, MilesTek has become a global source for cable assemblies used not only in aerospace and military avionics but industrial and government projects as well. One thing we have learned is that technological advances in these industries can make it difficult to know how to choose the right assembly for your needs. With that in mind, we’ve simplified our main cable options below by dividing our assemblies into four groups and summarizing their features and applications.

MIL-STD-1553 Bus and Stub Cable Assemblies

  • 100-ohm twinaxial cable assemblies are best suited for deployment in bus networks that are subject to rigorous use or environmental extremes. The three-slot TRB connectors are robust and the cable can withstand temperatures up to 200°C.
  • Three-slot, solder/clamp, plug to plug assemblies are best suited for typical bus networks that are not subject to environmental extremes. Some of them feature a steel spring for bend relief.
  • Bus and scope test cable assemblies are made with standard test cable and are used in labs and testing facilities. They combine one center twinax cable with two coax cables.
  • High-temperature, three-slot, full-crimp assemblies are rated to handle high temperatures and are suitable for vehicle applications.

Coaxial-RF Cable Assemblies

These assemblies employ a huge variety of standard cable and connector types. They are perfect for RF applications such as WAN/LAN, wireless, GPS, GSM, video, radio VHF, instrumentation and telecom.

Triaxial Cable Assemblies

We offer 50-ohm and 75-ohm triaxial assemblies with many connector combinations. Triaxial cable is like coaxial but with an added outer copper braid for shielding to increase bandwidth and protect the conductors from electrical noise. Triax cables’ many uses include high-frequency transducer data systems and precision low-current measurements.

Twinaxial Cable Assemblies

Twinaxial cable is also like coaxial but it has two inner conductors instead of one, plus a shielded braid around both wires. It is a cost-efficient option for short-range, high-speed differential signaling applications such as low-frequency digital and video distribution systems. We offer twinax assemblies with halogen-free and plenum-rated jackets as well as vacuum-rated TVAC cable assemblies.

For your urgent project needs, all of our assemblies have same-day shipping. View all of our standard cable assemblies or see our Cable Assembly Wizard for custom options.
