Microminiature Connectors
MDMH Hermetic
Our MDMH Hermetic Microminiature Connectors are ideal for applications that require more
robust sealing than can be achieved with epoxy resins. The MDMH uses size 24 AWG contacts
that are compression glass sealed through a steel shell and into a diallyl pthalate front-end
insulator. When mated, an interfacial seal provides environmental protection. We recommend
MDMH Hermetic receptacles be soldered to the chassis or container for a completely leak-proof
joint. MDMH Hermetic receptacles mate with standard MDM plugs.
