Coax Series Coaxial Feedthroughs

Coaxial feedthroughs are designed to transmit signals and data in vacuum and pressurized environments including vacuum chambers, control cabinets, and gloveboxes. Coaxial feedthroughs feature two conductors sharing a common axis. The inner conductor carries small signals and the outer conductor shields signals against electromagnetic interference. At Douglas Electrical Components, we manufacture custom hermetic coaxial feedthroughs to meet specific customer requirements. Our hermetic coaxial feedthroughs can be easily integrated with various connectors, including SMA – for low and high frequency, BNC (Type N, Mdot), MCX, MHV, SHV, SMC, TNC, UHF, and more. Alternatively, Customers also have the choice between a standard or custom bulkhead mechanical interface.

In addition to our coaxial feedthrough offerings, we also provide Triaxial Feedthroughs. With options such as Triaxial Bulkhead Connectors or Triaxial BNC Connectors, we offer versatile solutions to meet your specific needs. Whether you require standard configurations or customized designs, our expert team is dedicated to delivering high-quality Triaxial Connectors tailored to your design requirements increasing EMI shielding and frequency range.

Douglas’s engineering team will work with you to integrate hermetically sealed coax connectors or wire into the bulkhead fitting. Our SMA bulkhead feedthroughs are a popular choice for signal and data transmission in high-frequency applications. These SMA bulkhead feedthroughs feature space-saving designs and ensure shielded, low-loss transmission of high-frequency signals through the wall of vacuum systems. We can hermetically seal virtually any coaxial connector. We can also hermetically seal coaxial cables in any wire length. In addition to this, customers can also choose from a wide variety of hermetic feedthrough mounting styles, including jam-nut bulkhead, CF flange, KF flange, radial O-ring, and customized options. Our coaxial feedthroughs mounted on KF-style flanges are widely used in high vacuum environments for demountable connections.
