Rack and Panel Connectors
DPGM/DPJM/DPJMB
•Rectangular Rack/Panel Connectors
•Non-Environemental Single and Two-Gang
Configurations
Cannon's DPD Rack and Panel connectors are dis-
tinguished from other connector lines by their
rectanguiar shape which provides maximum space
utilization an rack or chassis mounted equipment.
The DPD is used in any commercial application
where moisture/ environmental resistance is not
required, such as I/0 connector or computer pan-
els, GFE test equipment, and GSE ground support
equipment. For example, one-half of a connector
assembly is mounted on a radio rack, or panel, and
the mating connector is attached to a cable that
connects to another instrument or rack. The DPO
has a temperature range of -55˚C to +125˚C
(-67˚F to +257˚F).
In addition to standard DPD connectors with solder
contacts, the DPDMA version has rear insertion, rear
release crimp, snap-in contacts that feature the LITTLE
CAESAR®, rear. release contact retention assembly
used in many other ITT Cannon
product lines.

DPD - Standard Rack and Panel Connector
Series
DPD connectors are the original rectangular rack
and panel connectors with solder type contact
termination, accommodating a wide range of con-
tact arrangements and a variety of endbells and
junction shells.
DPDMA - LITTLE CAESAR® Contact Assembly
DPDMA connectors are DPD's with the LITTLE
CAESAR contact assembly for rear insertion, re-
lease and extraction of crimp type contacts. Con-
tacts are inserted by hand, and extraction is ac-
compfished with the use of an expendable plastic
tool. Hard dielectric, closed-entry socket inserts
have lead-in chamfers for positive mating of pin
contacts during engagement. Both the DPD and
DPDMA connectors are intermateable.
DPD2 - Two Gang Version of DPD
DPD2 connectors are two-gang versions of the DPD
solder type connectors designed to handle double
the circuitry in instrument panel disconnect applica-
tions. The DPD2 is identical in shell style and
materials to the DPD, but features a center coupling
screw for positive engagement. Various coupling
devices are shown on pages 110 and 111. The DPD2
may also be ordered without the engaging device by
DPD2-34/DPD2MA-34
Receptacle
omitting the letter code "M" as shown in the
ordering nomenclature. Two optional polarizing
posts give up to six alternate insert positions (page
112).
DPD2MA - LITTLE CAESAR® Contact Assembly
DPD2MA connectors are DPD2 connectors with the
LITTLE CAESAR contact assembly for rear insertion,
release and extraction of crimp type contacts.
Contact insertion is by hand and extraction is by an
expendable plastic tool. Hard dielectric, closed-
entry socket inserts have lead-in chamfers for
positive mating of pin contacts during engagement.
DPD2 and DPD2MA connectors are intermateable.
