High-Performance RF Connectors

EI Sales connects engineers and OEMs to high-performance RF connectors manufactured by BEC. EI Sales provides RF connectors engineered for precision, durability, and minimal signal loss. We offer a full range of solutions rated across the spectrum, from low-frequency applications to GHz-level systems, ensuring your designs meet both electrical and mechanical demands.


With access to ruggedized and high-reliability product lines, we enable OEMs in aerospace, medical, defense, and industrial sectors to build systems that stand up to harsh environments and stringent specifications. Our RF connectors are manufactured in the U.S., delivering the consistent quality and performance required for mission-critical applications.

Custom and Standard Interface Options

Every system has unique requirements.  EI Sales offers a comprehensive portfolio that includes SMA, SMB, N-Type, TNC, and custom coaxial connectors, supporting a variety of impedance and frequency needs. Engineers can specify configurations for cable assemblies, board mounting, and bulkhead designs, tailored to system size, frequency range, and environmental requirements.



Our custom solutions support specialized form factors, integrated cable assemblies, and low-PIM requirements essential for advanced RF systems. With EI Sales, you can streamline design cycles by working with a partner who speaks your language.


Built for Critical OEM Applications

RF connectors are not all created equal, especially when used in industries where performance failure is not an option. From defense communication systems and aerospace navigation to medical imaging and industrial automation, our connectors are built to exceed the stringent demands of high-stakes OEM environments.


Industries such as aerospace, military, medical devices, and industrial systems depend on connectors that resist vibration, temperature extremes, and environmental exposure. Designed for vibration resistance, EMI shielding, and environmental sealing, our products ensure reliable signal transmission even under extreme conditions. With tight production controls and traceability, EI Sales delivers RF connectors that meet or exceed industry certifications, ensuring compliance with ISO, AS9100, and MIL-STD specifications.

What our partners say

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.

Engineer-to-Engineer Support

RF design requires precision, and so does RF connector selection. EI Sales bridges the gap between connector manufacturing and system design with direct engineer-to-engineer support. We collaborate early in your project, offering technical guidance on interface compatibility, signal integrity, and assembly techniques.



Our technical team works directly with design engineers to evaluate interface needs, advise on impedance matching, and recommend configurations that reduce loss and maintain signal integrity. Early technical engagement helps prevent costly redesigns and ensures that connectors are properly matched to the system’s electrical and mechanical needs.
