Trompeter Emerson high-temp twinaxial cablesDurable, high-performance cabling is the lifeblood of any connectivity system. And even the most reliable A/V distribution device or electronic component will fail to meet expectations if it’s connected with substandard cables. So we’re proud to sell a wide variety of bulk cable that meets our stringent quality standards.

For example, take a look at our new Trompeter/Emerson 78-ohm high-temp twinaxial cables with PFA jackets for MIL-STD-1553B applications

The premium, heavy-duty cable is constructed out of PFA (perfluoroalkoxy) outer jacket material and FEP (fluorinated ethylene propylene) insulation material, which, when combined, allow the cable to function at a high level even in both extraordinarily cool temperatures and extreme heat. More specifically, the cables can withstand temps ranging from 55-degrees Celsius below zero (negative 67-degrees Fahrenheit) to as much as 200-degrees Celsius (392-degres Fahrenheit).

The ability to perform flawlessly at such an extreme range of temperatures is important for high-performance, mission-critical applications involved with military avionics and commercial aviation. And, in this way, this twinax cable is similar to other high-temp cables we can provide, including twinax cables with Teflon jackets.

All types of bulk cable we sell are sold by the foot, but you will not find any cutting charges on your bill. Currently, this cable is available for just $3.50 per foot. To see a full list of applications compatible with this cable, just look at any product ending in “206” via our search bar.

(As a general reminder, you can keep an eye out for our latest products in the new products section of our website. Other recent connectivity solutions that we’ve added to our catalogs include coax extender sets, hi-def video conferencing systems, and twinax cable plugs.)

As we’ve mentioned previously, one reason we love MIL-STD-1553 technology is because it boasts roots powering some of the coolest technology imaginable — world-changing machines like the F-16 Fighter Jet. But beyond the “wow” factor, this also means that today’s MIL-STD-1553B solutions are rugged, reliable, and capable of providing turn-key solutions.

And, since it’s also our belief that “flexibility is the key to airpower,” we’re proud to stock a comprehensive catalog of MIL-STD-1553B solutions for maximum flexibility, including bus and stub cables, TRB connectors and Trompeter Connectivity Solutions.

So let’s explore how different aspects of MIL-STD-1553B can help you, starting with data bus couplers. We offer the industry’s most comprehensive line of MIL-STD-1553B data bus couplers, including:

Box style data bus couplersBox Style Data Bus Couplers

Our box-style couplers offer ideal solutions for a wide assortment of military, aerospace and commercial applications. We offer everything from 1-stub couplers to 8-stub couplers and everything in between. Each coupler category also includes single-, double-, and non-terminated couplers.


Inline data bus couplersInline Data Bus Couplers

Originally designed for airborne applications, our inline bus couplers are also available in a variety of styles, including everything from 1-stub couplers to 4-stub couplers, each available in single-terminated, double-terminated, or non-terminated models. These couplers take the rugged performance and utility of box-style couplers, shrink it down, and provide it in a smaller, but equally reliable form.


Bus kitsBus Kits

Comprehensive and cutting edge, our bus kits (available in both 2-terminal bus kits and 4-terminal bus kits) include box couplers, terminators, six-foot cable assemblies and a four-foot cable assembly.

We’re proud to offer all of these 1553B solutions with same-day shipping.

Design. Production. Component Sourcing. Design assistance. Custom harness assembly. Large volume production runs. Small volume production runs. Whatever aspect you need support for when it comes to MIL-STD-1553B technology, we can do it.

In fact, we’ve been providing these sorts of MIL-STD-1553 solutions to our diverse base of customers for more than three decades — all the way back when the amazing military-developed technology was just beginning to become more widely used for private sector solutions.

We enjoy working with MIL-STD-1553 technology for a handful of reasons: 1) It’s cool. Anything originally designed to run a piece of machinery as jaw-dropping as the F-16 Fighting Falcon fighter jet would be cool. 2) That demanding of an application requires the technology to be relied upon as “mission-critical.” 3) Military avionics uses will also necessitate an element of flexibility and adaptability.

Reliable. Flexible. Adaptable. Cutting edge. This is our kind of technology. We understand “mission-critical.” We live to come up with customized solutions using cutting-edge technologies for our customers that meet their unique and evolving demands and needs. We believe that “Flexibility is the key to air power,” and can accommodate production runs of all shapes and sizes.  We’ve worked hard to maintain a reputation for producing quick RFQ turnovers, bus coupler designs and efficient production timelines.

And we’re proud to be able to continue providing a of MIL-STD-1553 products and solutions still as a complete source for both the design and the production of MIL-STD-1553B devices and supporting equipment — as well of one of the most well-stocked resources of Trompeter/ Emerson Connectivity Solutions products anywhere on the globe.

MIL-STD-1553B solutions

For example, let’s take a look at our MIL-STD-1553B offers today:

Twinax Cables

Basically, twinaxial cables feature a two-conductor twisted balanced wire line and a specific impedance (at MilesTek, we provide both 78-ohm and 124-ohm twinax cables and accessories), plus a shielding braid around both wires. They’re similar are similar to coaxial cables, but, of course, with two inner conductors instead of one.

This construction matters for a couple reasons:

  • It lowers cable losses.
  • It provides protection against ground loops and capacitive fields.
  • By using more copper wire in a more tightly-weaved braid, it improves coverage to 90 percent (triax cables also benefit from this design).
  • It protects against low-frequency magnetic noise that passes through the copper braid.
  • By twisting the two balanced-signal-carrying wires, it makes it possible to cancel any random induced noise voltage pickup.
  • With two dielectric fillers under the braid, it allows the the signal pair to be separated away from the braid, lowering the leakage capacitance to ground.

As a result, twinax cables are a cost-efficient, effective option for short-range, high-speed differential signaling applications. However, the cables begin to lose their effectiveness around 15 MHz, after which transmission losses begin to increase. Therefore, they’re best suited for low-frequency digital and video distribution systems like connecting MIL-STD-1553 bus and stub devices.

Triax Cable

Triaxial cables are essentially coaxial cables with an added outer copper braid (basically, a shield), which is insulated from the signal-carrying conductors. The shield is grounded and passes both ground loop and capacitive field noise currents away from the signal-carrying coax.

Triax cabling can also be used in “driven shield” applications, where the inner conductor and the first braid are driven in parallel at the transmitting end, and work against the outer braid that’s insulated above ground. The inner braid is left floating at the receiving end, providing a sort of “Faraday shield” (which protects the internal conductors from electrical noise) between the inner conductor and outer braid.

This design is full of benefits, including:

  • Bandwidth and rejection of interference are increased.
  • The extra outer copper braid acts as a shield, protecting the enclosed coax conductors.
  • The grounded “shield” significantly improves signal-to-noise ratio (compared to, say, a standard coax cable).
  • The “Faraday” shield, significantly reduced the cable’s distributed capacitance.
  • Cable losses and loading are also reduced.

Triax cables are effective for a broad range of applications, including high-frequency transducer data systems and precision low-current measurements. Also, the outer braids are useful as a low-impedence transmission line.

Both of these solutions are available in MileseTek’s new Mil-Aero/RF Interconnect Solutions catalog.
