Full-Service Custom Cable Assembly Solutions


EI Sales connects engineers and OEMs to high-quality custom cable assembly solutions manufactured by BEC. Designed for performance and built for reliability, these assemblies are tailored to meet the electrical, mechanical, and environmental demands of complex systems. Industries such as medical devices, aerospace, industrial automation, and transportation rely on BEC’s cable assemblies to maintain signal integrity and power delivery under challenging conditions.


We support projects at every stage, from initial concept and design assistance to prototyping and full production. Our partnerships with U.S.-based manufacturing facilities ensure high-quality, consistent builds with short lead times and full engineering collaboration. Whether you need simple point-to-point wiring or complex multi-branch harnesses, EI Sales offers the expertise to bring your designs to life.

Built for Performance, Durability, and Integration

BEC’s assemblies are built with quality materials and robust construction techniques to ensure durability against mechanical stress, vibration, moisture, and temperature extremes.


Assemblies are available with a wide range of conductor types, shielding options, and jacket materials to match specific application needs. We focus on industries where failure is not an option: medical devices, aerospace systems, defense electronics, industrial automation, and specialized vehicles. Every assembly is manufactured to precise specifications to ensure mechanical durability, electrical performance, and environmental resistance, even under extreme conditions.


With full functional testing and rigorous quality controls, you can expect solutions that perform reliably for the life of your product.

Customization Options to Match Your Requirements

Every project has its own set of challenges. BEC offers a full range of customization options for cable assemblies, including conductor counts, wire gauges, connector types, shielding configurations, and labeling. Overmolding, strain reliefs, and ruggedized jackets can also be specified to meet environmental or regulatory requirements.


Through EI Sales, engineers and procurement teams gain access to detailed design support to ensure that cable assemblies are built to match project specifications precisely. Whether the priority is EMI shielding, flexibility, high-voltage tolerance, or resistance to harsh environments, we help select the right materials and construction methods for your application.

I just wanted to let you know that the five prototypes of the Glove 3.0 Main Board you built worked great. No errors and completely functional. Another exceptional job.  Please let everyone know that this is why I use Ninja for our prototypes. I believe you have or will be receiving the P.O. for the remaining 25 units.
