Profile: Hermetic Seal Corp. is a provider of electronic components and interconnect solutions for harsh environments. Our product line includes sealed connectors, sealed terminals, sealed headers, sealed packages and cable assemblies. Our battery & capacitor end seals are used to both store electrical energy (charge) and restrict/permit the flow of DC and AC current depending on the capacitance and frequency. These batteries provide power to a wide range of equipment, including: communications equipment, imaging devices, chemical agent monitors, and weapons system. Our sealed terminals and hermetically sealed headers are interconnect devices with single or multiple electrodes for isolation of electrical current or radio frequencies. A "terminal" is a device with a single contact pin. A "header" has multiple terminals inserted in a frame. Terminals and headers are widely used in electrical devices such as relays, transformers and capacitors as a means of allowing electrical feed-through while maintaining atmospheric insulation.
