Description:
Amphenol MIL-DTL-38999 Epoxy Sealed Hermetic Connectors offer superior electrical performance and a superior leak rate performance provided by an epoxy seal, coupled with the rugged design of a glass to metal seal connector.
Epoxy Sealed Hermetic Connectors are a lightweight alternative to glass sealed hermetic connectors and are available in custom configurations, including board mounting stand-offs and thru-bulkhead designs. These connectors utilize the same epoxy applied on Amphenol’s EMI Filter connectors.
