Rack and Panel Connectors
DPGM/DPJM/DPJMB
Environmental, Rectangular Connectors for
Aircraft, Missile and Ground Support
Equipment Applicatoins
Cannon's DPGM, DPJM, and DPJMB connectors are
designed for applications where space and weight are
prime considerations. Their rectangular shape
provides maximum space utilization and permits
easy removal of equipment for inspection and/or
repair. DPGM and DPJM connectors feature crimp
snap-in contacts with ring-type retention while
DPJMB connectors feature the LITTLE CAESAR®
rear release contact retention assembly (rear insertion,
release and extraction of crimp snap-in
contacts). They both have one piece diallyl phtha-
late insulators with polychloroprene wire sealing
grommets. They also incorporate a peripheral seal
design that allows an axial tolerance of up to .125
(3.175) while still effecting a seal. The 34 shell
utilizes a rubber seal encased in such a way that the
step down design of the mating 33 shell seats into
and against it.
All of these connectors utilize keystone corners for
polarization and are coupled by friction. Two shell
styles with different mounting provisions are avail-
able.
For all new applications, the referenced connectors
will be available only with insulators in the normal
position, that is, pin insulators in the 34 (receptacle)
shells and socket insulators in the 33 (plug)
shells.
For replacements it is suggested that where pract-
ical, customers using these connectors with re-
versed insulators change to connectors with
insulators in the normal position. However, for those
who are unable to change we will furnish connect -
tors with reversed insulators to maintain their
equipment usage.

MODIFICATION
Contacts, coaxials and junction shells must be
ordered separately, except for the DPJMB where
the contacts are supplied with the connector. When
(ordering or reordering) please specify the 3-4-3
contact part number as shown. We have cross-
referenced these new part numbers with the previ-
ous part numbers (which have been obsoleted) for
vour convenience.
