PXA - Single Shell DPX
PXA connectors are one-piece shell miniature
ack/panel connectors. The construction offers
igh strength and maximum utilization of insert area
for contact arrangements accommodating up to 106
contacts. Shells are keystone-shaped for polar-
zation. Operating temperature for the DPXA is
-54.2˚C to +125˚C (-67˚F to +257˚F).
PXB - Polarized ARINC Shell
DPXB connectors are DPXA connectors with an
ARINC B shelf. Additional polarization is provided
y three hexagonal polarizing posts.
DPX2 - Two Gang DPX Series
DPX2 connectors are the original two-gang versions
f the DPX, and are made of the same materials and
ccommodate the same contact arrangements.
eystone 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
PX2-A connectors are DPX2 connectors with an
RINC A shell. This shell type has the receptacle
lange placed .344 (8.74) from the front of the
engaging portion of the shell, and short aluminum
lloy polarizing posts permit polarization before
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 Ass embly
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
DPX*ME connectors are DPXMA connectors with
environmental interfacial and grommet seals, and
olive drab shell finish.
eceptacle 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
PX2-B connectors supersede the DPX2-A and
have an ARINC B Shell. This Shell type has the
Cadmium plate with yellow chromate
Melamine or Phenolic
Screws & Lockwashers
Cadmium plate with yellow chromate for MA: olive drab for ME
Diallyl phthalate or epoxy
