PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use
and low volume applications. A wide selection of powered application equipment for extended-use, production operations is available.

1. INTRODUCTION
SDE (Two-Piece) Crimping Die Assemblies are
designed to crimp a variety of connectors when used
in PRO-CRIMPER* III Frame Assembly 354940-1.
Refer to Figure 5 for a list of connectors and their
associated dies.
Catalog 1307191 provides a guide for cable-to-
connector selection. For connectors not referenced in
the catalog, contact Tyco Electronics Product
Engineering for recommendations.
Refer to instruction sheet 408-9930 for information
concerning PRO-CRIMPER II Hand Tool Frame
354940-1.
Dimensions in this instruction sheet are in
millimeters [with inches in brackets]. Figures are for
reference only, and are not drawn to scale.
Reasons for reissue of this instruction sheet are
provided in Section 8, REVISION SUMMARY.
2. DESCRIPTION
Each two-piece crimping die assembly consists of an
indenter die and an anvil die, which when closed forms
two or three crimping chambers. The larger crimping
chambers crimp the ferrule of the connector onto the
coaxial cable. The smaller crimping chamber crimps
the center contact onto the center conductor of the
coaxial cable. Each die is held in the PRO-CRIMPER
III hand tool jaws by a single screw. See Figure 1.
3. DIE INSTALLATION
(Figure 1)
1. Close the tool handles until the ratchet releases,
then allow the tool handles to open fully.
2. Install anvil die in the movable jaw of the tool
frame. Align the die with the retaining screw hole,
then secure die with the die-retaining screw. Do
NOT fully tighten.
3. Install indenter die in the stationary jaw of the tool
frame. Slowly close the tool handles, allowing the
dies to align themselves.
Once the anvil has entered the indenter, place a
copper bus bar (1.57 ± 0.05 [.062 ± .002] diameter)
into the center contact crimping chamber of the die
assembly.
4. Close the tool handles completely.
5. Securely tighten both screws with the appropriate
screwdriver.
4. CRIMPING PROCEDURE
Select the appropriate cable size and connector. The
wire size and insulation diameter must be within the
specified range for the connector.
This tool is provided with a crimp height adjustment
feature. Initially, the crimp height should be verified.
Refer to Section 5, Crimp height Adjustment, to
verify crimp height before using the tool.
For detailed information on cable strip lengths and
proper assembly of the connector, refer to the
instructions packaged with the connector. Make sure
that the connector's ferrule has been placed onto the
cable, and that the cable's braided shield is flared
away from the cable. Then proceed as follows:
4.1. Crimping the Center Contact
(Figure 2)
1. Close the tool handles until the dies are partially
closed.
2. Assemble the center contact onto the cable
center conductor and place the center contact in the
smallest crimping chamber of the anvil die.
Make sure the flange on the end of the center
contact butts against the die.
