Douglas Electrical Components Mechanical Interfaces: Feedthroughs by Housing Type

Douglas Electrical Components manufactures standard and custom hermetic electrical feedthroughs in various housing styles and configurations. Depending on the application, existing hardware, or design constraints, Douglas will partner with you to find the right housing to meet your application demands. With in-house CNC and machine tooling as well as a strong network of outside resources, our team is prepared to support custom designs in competitive lead times while keeping costs down and quality up. Vacuum CF Series Conflat Feedthroughs Hermetic CF feedthroughs designed to your electrical connection requirements Custom Housing Seals Customer-Supplied Housing Feedthroughs Create lightweight, low-profile hermetic assemblies using your existing housings and hardware. Face Seals Face Seal Feedthroughs Designed for vacuum and positive pressure applications. NPT Feedthroughs & Conduit Seals Stop pouring your own seal and rely on a plug-and-play, reliable solution approved for hazardous and non-hazardous locations. KF Series KF Feedthroughs Hermetically seal any electrical conductor or optical fiber in a KF, NW, or QF-type flange. SAE Series SAE Feedthroughs Hermetically seal connectors, wires, cables, terminals, circuits and optical fiber with an SAE mechanical interface. Portplate Series Custom Hermetic Flange & Plate Assemblies Multi-port hermetic assemblies accommodate any feedthrough configuration, with time and troubleshooting minimized. Hermetic assemblies are available in a variety of materials from plastic, brass, and aluminum to stainless steel and specialty nickel alloys for more corrosive applications. We have the capability to also use customer-supplied housings to directly cast the electrical connection to hermetically seal it to maintain a low profile, light weight, or seal within complex geometry. Our high-strength, hermetic epoxy is chemically inert, providing a hermetic seal between any conductor type and the mechanical interface. This includes wires, cables, connectors, printed circuits, flex/rigid circuits, and optical fibers. In the development of a hermetic assembly, incorporating Design for Manufacturing (DFM) principles involves optimizing the design to ensure that the manufacturing process is efficient, cost-effective, and of high quality, leading to a seamless production of the feedthrough while minimizing potential issues and delays. Our team will integrate other electrical components into the design such as shielding, connectors, and cable harnesses directly into the assembly for plug-and-play operation. Utilizing LEAN manufacturing, our assembly process is designed to support production volumes from single piece orders to hundreds of thousands of pieces. Our feedthroughs and assemblies are manufactured in Randolph, NJ to ISO 9001 standards with IPC-620 trained technicians (AS9102 First Article Inspections available upon request; contact factory).

Electrically and hermetically tested to ensure quality. IPC-620 certified technicians provide the basic hermetic seal and cable harness work like labeling, bundling, twisting, shielding, filtering, solder, and crimping. Chemically compatible with a variety of liquids and gases Choose from mechanical interface materials including MIL-certified stainless steel, brass, plated steel, or lightweight options of aluminum, titanium, and plastics Use a variety or combination of wire and cable materials, wire conductor types, gauges, and lengths Integrate hermetic seals directly into active sensing elements, circuit boards, and flex circuits to save weight and space FAQ What are some standard housing materials? Douglas offers a variety of standard housing materials including brass, aluminum, and stainless steel. Additionally, we can machine and hermetically seal plastics, specialty alloys, and more. The material type will depend on the operating conditions such as the pressure and temperature; contact our design engineers to review your application. How do you test your housings for leaks? Depending on the fitting and customer requirements, we have two standard tests. First, we offer helium leak testing via mass spectrometer. Second, we can offer pressure testing in-house up to 15,000 PSI for high pressure applications. All assemblies are 100% tested (no lot testing) to ensure each hermetic assembly meets our quality standards. Our in-house machine shop ensures that tooling is developed to properly test and verify each assembly. How do I calculate the wire density in a feedthrough? Our standard catalog has some basic information on wire density, yet it is best to contact our team. We will review your requirements and combine the correct wire gauge and conductor count for the housing size to ensure the proper fit, performance, and highest density possible while maintaining all electrical performance properties. Do you offer hermetic assemblies for explosion-proof applications? Yes. Our NPT line of hermetic electrical feedthroughs (commonly referred to as conduit seals or wire bushings) are available with approval to Class I Division 1 Explosion-proof. Contact us for ATEX availability as well. Can the housing be designed with additional features such as integrated shielding or grounding? Yes. Our technical sales engineers will work with you and your team to integrate connectors, shielding, grounding or any other design features to make the installation process seamless. How do you address potential issues like outgassing in vacuum or space applications? Douglas employs a low-outgassing hermetic epoxy to its hermetic electrical feedthroughs and assemblies.
