Professional Cable Assembly Solutions Delivering Quality, Reliability and Efficiency
TensAcc designs and manufactures custom cable assemblies for companies that need things done right. From early prototypes to low-volume production, we support medical, industrial, aerospace, and specialty applications with in-house overmolding, tooling and testing capabilities.
Founded in 1978 and a family-owned manufacturer based in Minnesota, we’ve spent over 45 years solving your cable assembly challenges. We work closely with both startups and OEMs, bringing deep hands-on experience, practical design insight, and a collaborative approach that helps customers move faster, especially with tight timelines and evolving designs.
Here’s how it works
Simple, straightforward, with clear communication and experienced builders focused on getting it right.
Every project begins with a discussion. We review your requirements, application environment, quantities, and timeline.
We evaluate materials, connectors, strain relief needs, shielding, and environmental factors.
Prototypes are produced quickly so you can test, validate, and confirm performance before moving into production.
Our team builds each assembly using controlled processes, proper documentation, and consistent workmanship.
Every assembly undergoes continuity testing and insulation verification before it leaves our facility.
We ship throughout Minnesota while staying involved and responsive even after delivery.
trusted by industry leaders
Quality and compliance are built into every assembly we manufacture.
Manufactured using materials that meet RoHS requirements, restricting hazardous substances commonly regulated in electronic components.
Built with materials aligned to REACH standards, supporting responsible chemical use and supply-chain transparency.

Frequently Asked Questions
TensAcc is a Minnesota-based contract manufacturer specializing in custom cable assemblies and custom molded cable assemblies. We build overmolded cables, medical leadwires, sensor cables, and wire harnesses for industries including medical devices, aerospace, industrial automation, and agriculture, with most production done in the USA.
Cable overmolding is a process where thermoplastic or rubber material is molded directly over a cable connector or strain relief to create a sealed, durable, and professional assembly. It's used in medical, industrial, and agricultural cables to protect connections from moisture, stress, and physical wear. TensAcc offers full overmolding services in-house with 8 molding presses and thousands of existing molds, which often means lower tooling costs for you.
Yes. TensAcc specializes in low-volume and prototype cable assembly runs. We help startups move from concept or drawing to finished, tested cables quickly and affordably, including design assist when you don't have a completed drawing yet. Our in-house mold library and segmented tooling can significantly cut your upfront tooling investment compared to most manufacturers.
TensAcc builds custom cable assemblies for medical devices, aerospace, industrial automation, automotive and mobility, agriculture and heavy equipment, biomedical devices, mining, and board-to-board applications. We serve both early-stage companies and established OEMs across the United States and internationally.
TensAcc is known as a go-to resource for urgent cable assembly needs. When materials are on hand, we can deliver assembled and tested cables within days, including rush overmolding, soldering, and crimping done at our Minnesota facility. We handle emergency builds, mid-run fixes, and 3D-printed tooling solutions to keep your project on schedule.
TensAcc is located in Minnesota and manufactures the majority of assemblies domestically. We ship throughout the United States and internationally, with active customers on the East Coast, Southwest, and overseas. For high-volume orders where domestic production isn't cost-effective, we work with a trusted offshore partner.
