annon's DPGM, DPJM, and DPJMB connectors are
d
esigned for applications where space and weight are
p
rime considerations. Their rectangular shape
p
rovides maximum space utilization and permits
e
asy removal of equipment for inspection and/or
r
epair. DPGM and DPJM connectors feature crimp
s
nap-in contacts with ring-type retention while
D
PJMB 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-
l
ate insulators with polychloroprene wire sealing
g
rommets. They also incorporate a peripheral seal
d
esign that allows an axial tolerance of up to .125
(3.175) while still effecting a seal. The 34 shell
u
tilizes a rubber seal encased in such a way that the
s
tep down design of the mating 33 shell seats into
a
nd 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.
F
or replacements it is suggested that where pract-
ical, customers using these connectors with re-
versed insulators change to connectors with
i
nsulators in the normal position. However, for those
w
ho are unable to change we will furnish connect -
t
ors with reversed insulators to maintain their
equipment usage.
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.
