1. INTRODUCTION

SDE (Two–Piece) Crimping Die Assemblies are

designed to crimp a variety of connectors when used

in PRO–CRIMPER* II 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.

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 II hand tool jaws by a single screw.

See Figure 1.

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.

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.

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

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.

NOTE

4. Close the tool handles completely.

5. Securely tighten both screws with the

appropriate screwdriver.

NOTE

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.

NOTE

3. Holding the cable in place, close the tool

handles until the ratchet releases.

4. Allow the tool handles to open fully and remove

the crimped center contact from the dies.

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.

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.

Make sure the flange on the end of the center

contact butts against the die.
