MDMH connectors are ideal for applications

requiring a better seal than can be achieved

with epoxy resins.

The connector utilizes size 24 AWG contacts

that are compression glass sealed through a

steel shell and into a diallyl pthalate front end

insulator. An interfacial seal provides

environmental protection when mated. We

recommend MDMH receptacles be soldered

to the chassis or container for a completely

leak-proof joint.

MDMH receptacles mate with standard MDM

plugs.

Features

• Hermetically sealed connector designed for

those applications where a vacuum, inert

gas or a constant controlled pressure are

required to eliminate adverse effects creat-

ed by atmospheric changes.

• Steel shells to provide greater strength, pre-

vent chipping, cracking or breaking, offer

electro-magnetic (EMI) and RFI shielding.

• Silicone elastomer compression interfacial

seal to provide a moisture and humidity

seal between each contact and between

contacts and shell.
