What is M17/176-00002 Wire?

M17 is the military standard for coaxial cables which are used to maximize performance in difficult situations that the military might encounter. M17/176-00002 is a variation of M17 coaxial cable called twinax cable. Twinax is similar to coaxial cable, however it has two inner conductors instead of one. This cable is used for high frequency signal transmission.

M17/176-00002 Construction

As stated above, M17/176-00002 is a variation of coaxial cable that is a twinax cable. Its 2 inner conductors are 24 AWG, each 19/.005 silver coated copper alloy. This cable has two solid Polytetrafluoroethylene (PTFE) dielectric cores. These cores are twisted together and filled with two PTFE rod fillers. The outer conductor is a single braid of 38 AWG, silver-coated, high strength alloy. The inner braid has 95.4% coverage and the outer braid has 94.6% coverage. M17/176-00002 has a Perflouroalkoxy (PFA) type XIII jacket with an overall diameter of 0.129 inches.

Allied Encyclopedia: M17 and RG Coaxial Cables

Allied EncyclopediaM17 coaxial cable? RG coaxial cable? All of these cable designations and specifications for different types of coaxial cable can get confusing, especially with how often the same standards seem to evolve.

M17 and RG standards both refer to coaxial cable, but they are not exactly the same. See how the designations differ and learn about the continuing changes in military specifications for the wire and cable industry.

Let’s start with the oldest first. RG coaxial cable designations are the old military standards for coax; RG meaning “radio grade.” They are still popularly used to refer to parts, but they have been officially discontinued by the military. You will mostly hear RG coaxial cable part numbers used by commercial industries, corresponding to the different types of connectors used in their products. There are a wide range of products still available under their RG numbers, and the differences between these numbers can depend on one or more things, including a material change or difference in ratings. Because the RG standard is no longer controlled by the government, even products with the same RG number are not guaranteed to be exactly the same, so it is important to check product specifications.

M17 refers to the military specifications (Mil-Spec) set by the U.S. Department of Defense. Mil-DTL-17, or M17 for short, is their standard for coaxial cable. They replaced the old RG numbers and ensured that the new M17 coaxial cables would stand up to tough military requirements in extreme applications and environments.

While the Mil-Spec numbers are still common, they are also being transitioned out of the industry. The government often releases cancelled or inactive standards to the hands of non-government standards bodies, like the Society of Automotive Engineers (SAE) and the National Electrical Manufacturers Association (NEMA). These independent organizations develop standards that address the quality and safety of cable products, and both SAE and NEMA are in the process of updating and converting a selection of Mil-Spec numbers into their own standards.

No matter what kind of cable you are ordering or what identifying standards are associated with it, make sure to read every specification sheet closely. This is an important step to ensure that you choose the appropriate product for your application requirements and the standards you need.

Allied Encyclopedia – Shipboard Cable

Allied EncyclopediaThe term “shipboard cable” covers a wide range of wire options. Different shipboard cables can be used for power, communication, control, lighting, electronics, instrumentation, and even other specialized applications. They are also diverse in terms of the people who use them: everyone from the U.S. Navy to recreational boaters.

No matter what the application or who the user is, shipboard cable must prove safe, effective, and reliable in any situation. Standards help manufacturers and end-users ensure that shipboard cable is designed to meet all product quality and safety requirements necessary for successful application on the seas.

If you take a closer look at any of our shipboard cable specifications, you will see that the mil-spec numbers are followed by series of letters. Each series represents a different version of that particular mil-spec cable. The letters let us know more about each one, including whether the cable is armored or unarmored, and whether or not the cable is watertight.

The following letters are associated with cable characteristics:

  • O =  Unarmored
  • A = Armored
  • S = Shielded
  • W = Watertight
