USB Feedthroughs

USB feedthroughs are used in vacuum and pressure applications for seamless data and power transfer. At Douglas Electrical Components, we provide hermetically sealed USB feedthroughs for these applications. Our USB vacuum feedthroughs combine multiple USB connectors or cables into a single feedthrough using hermetic epoxy sealing. Our feedthroughs are available in standard flange and face seal packages and customized housings with radial O-ring feedthrough .

Epoxy sealing creates hermetic sealing that enhances the performance of USB feedthroughs. This sealing prevents gas or liquid ingress and maintains a stable environment in the vacuum chamber. It helps create airtight connections and equip devices to withstand pressure differentials, extreme temperatures, and other environmental factors. The epoxies we use for sealing can resist chemicals, which makes them ideal for vacuum applications where they may be exposed to gases, fuels, and solvents. Epoxy technologies ensure faster data transmission rates than hermetic USB feedthroughs using glass-to-metal sealing. Hermetically sealed USB feedthroughs provide an extra layer of protection, ensuring the reliability and longevity of the device.

Epoxy technology enables us to create high-density feedthroughs that can accommodate various types of conductors and connections, thereby offering us flexibility and adaptability to specific project requirements. At Douglas Electrical, we primarily work with USB-A and USB-C connectors, which are commonly chosen for their high-speed data transfer and power flow features. However, we can also combine other types of connections to create a high-density connection that minimizes the space and hardware needed to penetrate your vacuum chamber, glovebox, or system. This means, we can also create USB Feedthroughs to accommodate USB 3.0, USB 2.0, USB C, or USB sealed C connectors.

At Douglas Electrical, we can create backpotted connector assemblies featuring USB connectors such as the MIL-DTL-38999 connector interface, which more common in military and aerospace applications.
