Why Hermetic Sealing is Crucial for Space Electronics April 24, 2024

Space electronics are designed to withstand extreme conditions. They are used in many critical applications, such as navigation, scientific data collection, communication, and operational controls. These electronic devices are expected to operate reliably and efficiently in challenging conditions, such as vacuum, drastic temperature fluctuations, and high levels of cosmic radiation. This condition necessitates specialized approaches […]

Hermetic vs. Environmental Connectors: Which is Right for Your Application? March 22, 2024

Connectors are used in electronic devices to establish connections between components and cables, ensuring smooth signal transmission. Although designed to ensure efficiency and performance of components, these connectors may need additional protection in challenging work environments. This is where environmental and hermetic connectors gain prominence. Both these types are designed to protect components against contaminants […]

Seal Tight Connectors vs. Line Bushings February 15, 2024

Seal tight connectors, also referred to as Sealtite connectors are electrical cable glands used in hazardous locations. Wire or cable passes through the center of the fitting with a locking nut that tightens to the outside diameter of the cable jacket. Various configurations are available, each with hazardous area ratings. Seal tight connectors offer a […]

High Voltage Feedthrough Solutions: Design, Types, and Applications January 17, 2024

Douglas Electrical Components manufactures hermetic feedthroughs for high voltage wire, cable, terminal, and connector applications. Utilizing a proprietary hermetic epoxy material and process, Douglas can seal wires , cables and connectors to 30kV and stud terminals over 20kV in a variety of applications and industries. Transmitting high voltages can be its own challenge but […]

Mastering Cable Potting: Hermetic Seals for Demanding Applications January 8, 2024

Cable potting involves encasing conductors in an epoxy, liquid, or gel within an enclosure or feedthrough housing. Douglas Electrical Components employs a proprietary hermetic epoxy to seal wire and cable feedthroughs requiring cable potting. Cable potting is often done in-house by OEM’s or through some Douglas competitors. Differences can arise in the potting encapsulation compound, […]

Wire Feedthroughs and Line Bushings Versus Conduit Cement Compound December 15, 2023

Douglas Electrical Components wire feedthroughs and line bushings are often compared to wire feedthroughs that are hermetically sealed using conduit cement within a metal housing. Conduit cement is a traditional bonding substance for sealing electrical systems and conduits whereas epoxy in wire feedthroughs and line bushings can be more suitable for preventing the entry of […]

Design for Manufacturability (DFM) in Hermetic Feedthroughs February 23, 2023

Design for Manufacturability, or DFM, is the practice of designing products in a way that makes them easy and cost-effective to manufacture. This is especially important in the field of hermetic electrical feedthroughs. Hermetic electrical feedthroughs provide a sealed electrical connection between the inside and outside of a sealed enclosure. They are airtight and withstand extreme environments, […]
