Minnesota Wire Custom Designs, Develops, and Manufactures Wire, Cable, and Interconnect Assemblies.

Home 1

We excel at solving unique and difficult interconnect problems.

Minnesota Wire has been engineering and manufacturing custom solutions for complex cable assemblies since 1968. We are a full-service development and manufacturing house for wire, cable, harness, and interconnect assemblies.

We are vertically integrated.

Vertical integration is a rarity in the wire and cable business. It means we can expedite your project from concept to production—all in our facilities. Our in-house capabilities include concept design, prototyping, design verification, production, and product validation.

We have state-of-the-art testing facilities and a full R&D department. We use these assets to support prototyping and to ensure that every detail of your project meets your specifications.

Whether you need wire and cable, or wire and cable assemblies with custom connectors in a unique configuration, we would welcome the opportunity to assist you with your next custom project.
