Cannon's DPXNA and DPXNE are rack and panel connectors designed for military, aerospace, and computer periphery equipment applications. They are designed to operate in temperatures ranging from -65°C to +125°C and meet or exceed the requirements of MIL-C-81659. The connectors are available in single, 2, 3, and 4 gang configurations and can accommodate 12 contact arrangements, contact sizes 12, 16, 20, and 22, and combination standard and coaxial contacts. The crimp snap-in contacts are retained by the LITTLE CAESAR® rear release contact retention assembly. Environmental sealing is achieved through wire sealing grommets and interfacial seals. The shell cavity locations are specified in the insert designation number in the charts.
This handbook describes the DPXNA (non‑environmental) and DPXNE (environmental) rack and panel connectors that meet MIL‑C‑81659 Revision B. It covers the connector series, shell styles, contact arrangements, material specifications, and environmental sealing methods.
The document provides ordering tables, mechanical dimensions, panel cutout layouts, contact and termination tooling data, and a list of accessories such as junction shells and dust caps. Modification codes and ARINC‑404 compliance details are also included.
