ARINC 404 DPX

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.
DPXA-34 DPXB-33

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
DPX2-34B DPX2-33B
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 DPX2-B - ARINC B Shell receptacle flange placed .060 (1.52) from the front
alloy polarizing posts permit polarization before DPX2-B connectors supersede the DPX2-A and of the engaging portion of the shell, and polarizing
contacts engage. have an ARINC B Shell. This Shell type has the posts permit polarization before the shells 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 DPX3-34 DPX4-33
with 99 polarizing positions.

DPX*MA - LITTLE CAESAR' Contact Assembly DPX*ME - Environmental with LITTLE CAESAR
DPX*MA connectors are DPX connectors with the Contact Assembly
LITTLE CAESAR contact assembly for rear in- DPX*ME connectors are DPXMA connectors with
sertion, release, and extraction of crimp type con- environmental interfacial and grommet seals, and
tacts. Insertion requires no tool; extraction requires olive drab shell finish.
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.

**Crimp rear release coaxial contacts.

†A106 arrangements have the POS-ALINE connector design. See below.
NOTE: Engaging force of each layout arrangement shall not exceed 45 lbs. maximum.

Positive Contact Alignment Design

For high density A106 contact arrangement
PLUG INSULATOR RECEPTACLE INSULATOR

PIN SOCKET

In the POS-ALIGN connector construction the entire pin contact is recessed in an individual cavity in the
plug insulator while the sturdy socket members are exposed and extend from the connector receptacle face.
There is a lead-in chamfer that guides the socket contact into the pin cavity assuring proper contact
alignment during mating and protecting the pin contact from damage and wear.

Coaxial Contact Assembly Recommendations
(For Codes A, B, C, D, E, J, K, L and P) (For Codes A, B, C, D, E, J, K, L and P)

1. Center contact, rear insulator, crimp ring, support bushing and seal sleeve are packaged separately and
shipped with the coaxial assembly.
2. Use impact extraction tool no. CET-C4 (038869-0004). An insertion tool is not required. (See Item 4). SOCKET
3. Cable Assembly Instructions
Step 1- If applicable, determine which portion of seal sleeve should be used. If seal 2 is used, cut off
seal 1 portion PIN
Step 2 - In sequence, place seal sleeve, support bushing and crimp ring over cable jacket.
Step 3 - Trim cable per illustration. SEALED
Step 4 - Place rear insulator over dielectric.
Step 5 - Solder innerconductor to center contact. SEAL 2
Step 6 - Insert soldered cable firmly into coaxial with shielding over coaxial shell. BUSHING
SEAL 1
Step 7 - Pull crimp ring forward until stopped and crimped.
Step 8 - Insert coaxial assembly into connector until engaged. Push support bushing into grommet
until shoulder rest on tublular extension. Then pull seal sleeve forward until it is snug
against grommet. SEAL
SOCKET
4. To extract coaxial, push back seal sleeve and support bushing. Then push out coaxial from engaging end
with CET-C4 (038869-0004) impact tool.
5. When crimping with CA58073 crimp tool, care should be taken to avoid flaring the front end of the
crimp ring. Place Crimp jaw so that the second tooth of the indentors is over the end of the crimp ring.
6. To facilitate extraction of contacts and avoid splaying the length of free cable adjacent to the rear BUSHING
surface of the connector should not be less then 2.000 (50.80). PIN

The last two digits in the DPX nomenclature (ex: DPXB-8-33B-0014) refer to the polarizing post position. When the last two digits are omitted it means the
polarizing posts will not be assembled and position number is not stamped on the connector. This allows the customer to position the posts themselves and then
stamp the appropriate number on the shell. If the last two digits are made 00 it means the polarizing posts are deleted.
