Stripping Instructions
ITT Cannon recommends resistance soldering for all
solder contacts, particularly for RF cable where
excessive heat will damage the dielectric. Wires
should be pre-tinned. Shells, bushings, endbells and
junction shells Jwhere applicable) must be slipped
over wire bundles before soldering or crimping is
started. The mechanical steps in wiring coaxials are
described below.
R Coaxial (Straight and 90 )
1. Cut cable even. Trim to dimensions shown on
tabulation. Care should be taken not to injure
the conductor or dielectric.

3. Remove solder pot cover. Insert cable and solder
conductor to contact. If a straight contact is
used, the dielectric should but against contact
solder pot.
2. Comb braid, tin conductor and remove flux. If a
90 contact is used, bend conductor 90 after
tinning.

4. Replace solder pot cover and solder braid to
ferrule.
Engaging Devices
Single Gang - DPD/DPDMA
The DPD/DPDMA can be engaged by means of a
No. 10-32 steel jack screw and clinch nut. This
coupling device is designed to fasten connectors
securely when they are used in other than standard
rack/ panel applications. The jack screws and clinch
nuts are mounted on the shell flanges at the factory.
They may be called out on either -33 or -34 shelis,
although it is preferred to have jack screws on the
-33 shell and the clinch nuts on the -34 shell. The
device can be ordered on both DPD and DPDMA.
How to Order
DPD-**-34*-1* N
DPD-**-33*-1* S
N = Clinch Nut
S = Jack Screw
The suffix "N" or "S" is placed immediately after the mounting
hole variation; i.e., - 1AN, -1AS, etc.
Two Gang - DPD2/DPD2MA
The DPD2 is engaged by means of a variety of
screw mechanisms. Engaging devices are inter-
changeable (within the thread group) with male or
female mounting on either 33 or 34 shells. The
accompanying tabulation lists the available engag-
ing devices, male opposite female, with which they
mate.
