Custom Cable Assemblies and Wire Harnesses for Defense
Defense applications often require assemblies built around specific electrical, mechanical, and installation requirements. MJM Industries manufactures custom defense cable assemblies and complex wire harnesses to customer specifications, incorporating the cables, connectors, materials, and manufacturing processes required for the application.
Depending on the design, assemblies can incorporate military-style connectors, NATO plugs, overmolding, potting and encapsulation, Class 3 wire processing, soldering, and other specialized processes.
Supporting Defense Program Requirements
MJM Industries is an ITAR-registered U.S. manufacturer with systems and processes that support defense program requirements, including:
- BABA compliance
- NIST SP 800-171
- CMMC cybersecurity
We also serve customers that are AS9100 certified, following applicable customer compliance protocols.



Overmolded Solutions for Harsh Environments
Overmolding can help protect cable-to-connector interfaces from moisture, high temperatures, mechanical stress, and repeated handling while providing strain relief and supporting ingress protection. MJM Industries manufactures custom overmolded cable assemblies around the connector, cable construction, and environmental requirements of the application.
In-house engineering, machining, and molding capabilities allow MJM Industries to design and manufacture custom tooling for overmolded configurations. Potting and encapsulation provide additional protection where required.
Manufacturing Support From Design Through Production
When a customer’s engineering team has established the electrical and system design, MJM Industries applies manufacturing expertise to help move the design into production. Depending on the project, support can include:
- First articles and prototypes
- Design for manufacturability
- Manufacturing process development
- Tool design and machining
- Production fixture design
- Part development
- Production planning and implementation
The Advantages of U.S. Manufacturing
MJM Industries manufactures in Northeast Ohio, with engineering, machining, cable and wire processing, overmolding, and assembly capabilities under one roof.
