Hermetic micro D connectors are used in applications where an enclosure needs to be isolated from the outside environment. Panel feed-through is the main application for this type of connector. In the vast majority of applications, the use of a hermetic encapsulant offers sufficient levels of hermeticity at a reasonable price. Only extreme environments require glass-to-metal sealing.

Furthermore, Sunkye fully tests its hermetic Micro-D solutions to provide reliability and satisfaction to its customers. Helium leak rate is the most common and most reliable method to quantify a small leak. Based on its expertise, Sunkye can also design tailor-made connectors to fit your application needs.

By mounting the flange to the panel, all Sunkye hermetically sealed electrical connectors can be used to maintain low or high pressure vacuum seals. They are fully compatible with standard Micro-D connectors. A wide range of products is already available, however, custom interconnect solutions can be designed for specific panel cut-outs and thicknesses.
