 HIGH VIBRATION PLUGPDS-229-2Dualok is a MIL-DIL-38999 Series III type plug connector with an enhanced antidecoupling mechanism designed to perform under severe vibration environments –far exceeding the typical military specification requirements.

HIGH VIBRATION PLUGFULLY CUSTOMIZABLEThe Dualok plug is proven to mitigate the negative effectsof high vibration operation by eliminating connector back-offand reducing conditions that can cause fretting corrosion.
Dualok is compatible with all D38999 Series III receptacleinterfaces and has been qualified to multiple customerspecifications.

Designed for the next generation of commercial jets, spacecrafts, or military vehicles. Dualok options include a fully composite coupling nut, tailored to more commercial applicationswhere maximizing weight savings (35%) is a must. For Military Rotocraft, a familiar aluminum connector with a hybridcomposite coupling nut can act in as the drop-in replacementthat provides weight savings and eliminates backing off underharsh vibration. The hybrid steel/composite design will fill thegap where high temperature, and durability meet. All Dualokconfigurations accommodate both commercial and mil-specinsert arrangements as well as standard D38999 contacts, andaccessories.

SUPERIOR ELECTRICAL PERFORMANCEWhen fully mated, Dualoks’ anti-decoupling mechanismeliminates back-off which is common issue among standardD38999 mated pairs. Dualok’s superior coupling ensuresreliable shell-to-shell bottoming which significantly improvesthe conductive path through the connector shells, thusimproving EMI shielding, lightning strike performance, andcontact interface sealing. When compared to D38999 SeriesIII aluminum mated pairs, equivalent Dualok pairs showedshell-to-shell conductivity values 75% better than the milspec requirements.
