DPXA - Single Shell DPX

DPXA connectors are one-piece shell miniature

rack/panel connectors. The construction offers

high strength and maximum utilization of insert area

for contact arrangements accommodating up to 106

contacts. Shells are keystone-shaped for polar-

ization. Operating temperature for the DPXA is

-54.2˚C to +125˚C (-67˚F to +257˚F).

DPXB - Polarized ARINC Shell

DPXB connectors are DPXA connectors with an

ARINC B shelf. Additional polarization is provided

by three hexagonal polarizing posts.

DPX2 - Two Gang DPX Series

DPX2 connectors are the original two-gang versions

of the DPX, and are made of the same materials and

accommodate the same contact arrangements.

Keystone shaped shells accommodate two DPX

inserts with up to 212 contacts. The DPX2 has

three polarizing posts with 99 polarizing positions.

DPX2 - A - ARINC A Shell

DPX2-A connectors are DPX2 connectors with an

ARINC A shell. This shell type has the receptacle

flange placed .344 (8.74) from the front of the

engaging portion of the shell, and short aluminum

alloy polarizing posts permit polarization before

contacts engage.

DPX3 - Three Gang DPX Series

DPX3 connectors are three-gang versions of the

DPX, made of the same materials, and accommo-

date the same contact arrangements. The three-

gang version can therefore accommodate up to a

total of 318 in the keystone shaped shells, with

three polarizing posts that are capable of providing

up to 99 polarizing positions.

DPX4 - Four Gang DPX Series

DPX4 connectors are four gang versions of the DPX,

made of the same materials, and can accommodate

four separate arrangements that can total up to

424 contacts. The DPX4 has three polarizing posts

with 99 polarizing positions.

DPX*MA - LITTLE CAESAR' Contact Assembly

DPX*MA connectors are DPX connectors with the

LITTLE CAESAR contact assembly for rear in-

sertion, release, and extraction of crimp type con-

tacts. Insertion requires no tool; extraction requires

an expendable plastic tool. A hard dielectric,

closed-entry socket insert has lead-in chamfers for

positive mating of contacts. Contacts are crimpable

with the M22501 tool.

DPX*ME - Environmental with LITTLE CAESAR

Contact Assembly

DPX*ME connectors are DPXMA connectors with

environmental interfacial and grommet seals, and

olive drab shell finish.

receptacle flange placed .060 (1.52) from the front

of the engaging portion of the shell, and polarizing

posts permit polarization before the shells engage.

DPX2-B - ARINC B Shell

DPX2-B connectors supersede the DPX2-A and

have an ARINC B Shell. This Shell type has the
