In order to receive a quote for custom Mil-Spec (or Military Specification) cable assemblies, the manufacturer will need detailed information and specifications. The more information you can provide to the manufacturer, the more accurate and robust the quote will be. At Quadrangle Products, there are several key design inputs that are helpful to know before quoting your cable assembly. If you are unsure about certain information, the team at Quadrangle will likely be able to help you figure out what specific design you need. What follows is a breakdown of the specifications you should provide when looking to purchase custom Mil-Spec cable assemblies.
What is the Application of the Cable/Wire?
Mil-Spec cables are designed and built to comply with military specifications. This means the connections are designed to protect against environmental invasiveness, which makes them great for military and aerospace applications, although they can be useful in all sorts of industries.
One of the first things a cable manufacturer should know before providing a custom Mil-Spec cable assembly is what the application of the cable is going to be. Where is the cable going to be used? Are there any constraints that could affect how the cable will function? Sharing as much information and being as specific in your intent will help you receive an accurate quote quickly.
Some of the questions to consider include:
- What industry is this Mil-Spec cable being used for? (Aviation, Transportation, etc)
- Is this a custom or existing design?
- What does the cable do? What is the intent?
- What is your timeline? When do you need the cables/wires?
- Are there qualification or test requirements?
- What quantities are required for samples and production?
What Connectors Do You Need to Use?
A cable’s connector is a metal and plastic interconnect that allows the wire’s internal copper conductor to be properly mated with the other parts of the assembly. Connectors tend to range in cost and complexity, so it’s a good idea to properly match the application with your connector scheme. Some connector systems have lower cost “equivalent” or “sub” options, offering a form, fit, and performance replacement.
- Manufacturer’s P/N
- Connector type and gender
- Orientation of the connector
- Locking and polarization
- Shielding
- Overmolded strain relief
Some of the base models in the Mil-Spec connector series that we carry include:
- D38999
- M28840
- 2M805
- MS27467
Environmental and Test Considerations
Many custom cable and wire assemblies require some degree of testing for quality assurance. Some applications will be subject to more rigorous environmental conditions and will need to be designed with that in mind. These tests can include submersion tests, pull and flex mechanical tests, or sophisticated electrical tests that need specialized instrumentation.
