MilesTek carries more than 30 types of connectors for MIL-STD-1553 applications. Do you need solder/clamp or full crimp? Bayonet or threaded? Straight or right-angle plugs?
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.
If you’re looking for MIL-STD-1553 components, you’re in the right place. Based on over three decades of experience, MilesTek has built its inventory to address military avionics, aerospace, industrial and government project requirements. We realize some guidance might be helpful as you browse our huge product selection.
MilesTek wants to simplify the sometimes confusing experience of deciding what data bus products you need and finding them. We’ve divided our big variety of data bus cables and connectors into seven product groups below, with a link to each one. If you already know what you need, scroll down and start browsing. But if you think you might benefit from a little guidance with some of the lingo you’ll encounter in the product descriptions
When it comes to temperature extremes, Death Valley and Antarctica have nothing on outer space. A typical communications satellite must be able to withstand temperature swings of more than 250°C. That requires specially made electronics, not only for the satellite but for the equipment that tests its components before it reaches the launch pad.
Every MIL-STD-1553B vehicle has a backbone of interconnected electrical components. When designing the vast array of sub-assemblies, factors can be overlooked regarding passive components such as couplers, cables and connectors. In particular, aircraft, with all their wiring, are susceptible to ,,,,
Data bus couplers must be placed between the main data bus and the vehicle subsystems, computer system, or terminal in order to protect the integrity of the entire network. The databus coupler is often called a ‘stub coupler’ where a ‘stub’ is simply a pair of wires connecting avionics components to the main bus.
Twinaxial cables feature a two-conductor twisted balanced wire line and a specific impedance, plus a shielding braid around both wires. They’re similar to coaxial cables, but, with two inner conductors instead of one.
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.
As with much of our nation’s IT infrastructure, the military designed MIL-STD-1553. In the early 1970s the new standard replaced analog point-to-point wire bundles between electronic instrumentation. In 1978, leaders upgraded to version MIL-STD-1553B as a way to boost compatibility between designs by different manufacturers, as well as enhance overall flexibility. The updated standard provided explicit specifics about electrical interfaces.
BNC (Bayonet Neill-Concelman) RF connectors make it easy to connect coaxial cables with radio-frequency equipment like radios and TVs, composite video on commercial video devices. The amount of ohms indicated basically measures electrical impedance along the coaxial cable. They’re easy to install with a simple “snap and lock” mechanism, which ensures a high-quality connection. They arrive tested to 3 GHz. And they come in handy when you need to combine them with, say, an RCA connector on the end of the coaxial cable.
