Cannon's DPD Rack and Panel connectors are dis-
t
inguished from other connector lines by their
rectanguiar shape which provides maximum space
utilization an rack or chassis mounted equipment.
T
he 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

Series
D
PD connectors are the original rectangular rack
and panel connectors with solder type contact
t
ermination, 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
t
ool. Hard dielectric, closed-entry socket inserts
have lead-in chamfers for positive mating of pin
c
ontacts 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 114-115. The DPD2
may also be ordered without the engaging device by
o
mitting the letter code "M" as shown in the
ordering nomenclature. Two optional polarizing
p
osts 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.

There was no evidence of breakdown when the test
voltages given were applied, for a period of one
minute, between the contacts and between the
shell and the contacts with spacings as noted.
