DEUTSCH 38999 Series IV connectors

DEUTSCH 38999 Series IV connectors

TE's DEUTSCH 38999 series IV connectors, qualified to MIL-DTL-38999 specifications, use a breech coupling mechanism that only requires 90° of rotation to engage and disengage.

Resist interfering signals. TE's DEUTSCH 38999 Series IV connector product line is designed and built using the superior breech lock coupling mechanism. Special grounding fingers form a 360-degree circle just inside the shell, acting as a shield. The connector is actually grounded when the shells meet, even before the contacts engage. The line also includes blind-mateable, Qualified Parts Listing (QPL) and modified connectors and custom cable assemblies.
