Key Features
The D38999/26JJ35PN plug provides ultra high-density interconnect capability for advanced aerospace and defense systems. Because it is manufactured to MIL-DTL-38999 Series III standards, it supports reliable performance in vibration-prone and harsh environments. In addition, the 128-position configuration enables complex signal routing within a compact shell. The threaded coupling mechanism also ensures secure mating under mechanical stress. Therefore, it is well suited for mission-critical electronic platforms.
Applications
Aircraft avionics systems
Military communication equipment
Defense radar assemblies
High-density sensor platforms
Industrial ruggedized signal interfaces
Advanced control system interconnects
Product Overview
The D38999/26JJ35PN from Amphenol is a 128-position straight plug designed for MIL-DTL-38999 Series III interconnect systems. It includes installed pin contacts, which simplifies harness integration and reduces assembly time. Because high-density connectors are critical in modern aerospace systems, this configuration supports efficient multi-circuit integration within limited panel space.
Moreover, the aluminum shell construction and conductive plating support shielding continuity and mechanical durability. This makes the connector suitable for aircraft platforms, military vehicles, and industrial systems exposed to vibration and temperature variation. In addition, Series III design characteristics ensure environmental sealing and long-term reliability.
As a result, engineers rely on D38999/26JJ35PN connectors when building compliant and high-performance interconnect assemblies. Cyndtek supplies new Amphenol components ready for immediate deployment.
