Douglas Electrical Components SAE Hermetic Terminal Seal 27404

StudSeal™ hermetic terminal seals provide a secure barrier for high current or high voltage transfers in sealed environments. Our products are designed for high vacuum and pressure applications, including air conditioning and refrigeration compressors, semiconductor processing equipment, vacuum furnaces, and power distribution equipment. Customize your terminal seal We also offer completely customized terminal seals with individual terminal ends or built as a multi-terminal plate assembly. The mechanical interface, number of terminals, and each terminal feedthrough end can be customized to meet the requirements of your specific application. While threaded terminals are most popular, other variations of threaded terminals as well as wires and connectors can be designed into a StudSeal feedthrough. Standard Designs Our standard hermetic terminal seals feature solid copper, heavy-current conductors sealed in NPT and face seal packages housing styles and stainless steel materials, with a hermetic, moisture-tight epoxy to seal between the conductor and housing. They are compatible with a wide range of liquids and gases, including refrigerants, oils, heat transfer fluids, and jet fuel, and comply with various certifications and standards. DATASHEET We manufacture custom designs for a range of production volumes to meet your fit, form, and functional requirements. Our products offer a moisture-tight seal for transferring power in and out of a sealed environment, and can handle operational loads of up to 1,000 amps and 15kV. Choose from standard or customized designs to meet your specific application needs. Contact us today to discuss your hermetic terminal seal and power feedthrough requirements.
