Sunkye Military/Space grade Micro-D sealed/ hermetic connectors are based on the highly reliable twist pin contact technology with a rectangular package for best performance. Environmentally sealed connectors are an ideal interconnect solution for heavy-duty and harsh-environment applications.




Sunkey R04J Series Solder Cup Glass-Sintered Sealed Connector+



Hermetic connectors which need sealed panel mount connector 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' hermetic Micro-D 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.
