Custom RF Connectors and Cable Assemblies

Promark Electronics manufactures a wide variety of custom RF Connectors and Custom Coaxial Cable Assemblies, including RG-58, RG 59, RG 62, LMR, Low Loss, semi-rigid and RG6 coaxial cables in Quad Shield and Tri Shield with BNC, F and other connectors. Our cable assemblies can be built from any number of materials and completed with connectors in almost any configuration, including right-angle connections.

Choosing the right connector

Selecting the right connector for your interconnect application is paramount, our expertise allows us to choose the best materials during the component selection process. We assess different factors such durability in harsh environmental conditions, current requirements and manufacturer ratings. Connectors have ingress protection (IP) designations for specific conditions, but the IP68 rating for example can be defined differently per manufacturer, this is an important factor that our design engineers know to navigate.

Thoughtful Design

Aside from build endurance and performance, thoughtful design must be applied. We leverage our 30 years of experience in various demanding markets to design quality custom connectors, whether it be a military application, mass transit or medical. We pride ourselves on creating accessible designs, as well as being at the cutting edge of small electronic parts assembly technology.

Quality and Testing

We are an ISO 9001:2000 certified manufacturer, specializing in simple and complex RF applications for a wide variety of industries. With our years of experience, we are able to produce large quantities of custom RF cable assemblies quickly. Each product and each build is subject to multiple in-process inspections. A final inspection, documented with our high-end ERP system, provides first-article quality for every one of our assemblies.

Performance and Quality

Signal integrity is the key purpose of a connector, there should be no weak links in an electronic application’s signal path. Quality build materials and thoughtful engineering are necessities in creating a high performance, high-bandwidth connector. Issues such as crosstalk, skew and propagation delay are just some of the factors that can compromise a project led by inexperienced engineers.
