1. INTRODUCTION
SDE Crimping Die Assemblies 91911-[ ] are designed
to crimp the center contact and ferrule of COAXICON
connectors when used in PRO-CRIMPER* III Frame
Assembly 354940-1. Refer to Figure 1 for die
assembly-to-connector cross-reference.

2. DESCRIPTION
Each die assembly consists of an indenter die and an
anvil die. Each die is held in the tool frame assembly
by a single screw (included with the tool frame).
When closed, the dies form two or three crimping
chambers. The larger crimping chambers crimp the
ferrule onto the coaxial cable, and the smaller
crimping chamber crimps the center contact onto the
center conductor of the coaxial cable.
3. DIE INSTALLATION
1. Close the tool frame handles until the ratchet
releases, then allow the tool handles to open fully.
2. Install the anvil die into the movable jaw of the
tool frame. Align the die with the retaining screw
hole, then secure the die with the retaining screw.
DO NOT fully tighten.
3. Install the indenter die into the stationary jaw of
the tool frame. Slowly close the tool handles,
allowing the dies to align themselves. After the anvil
die has mated with the indenter die, place a
1.57 ±0.05-mm [.062 ±.002-in.] diameter copper bus
bar into the center contact crimping chamber of the
die assembly. Secure the die with the retaining
screw. DO NOT fully tighten.
4. Close the tool handles completely.
5. Securely tighten both retaining screws.
4. CRIMPING PROCEDURE
Select the appropriate size cable and connector. The
wire size and insulation diameter must be within the
specified range for the connector.
Initially, the crimp height should be verified before
crimping the center contact or ferrule. Refer to
Instruction Sheet 408-9930 included with the tool
frame for crimp height adjustment.
NOTE
i
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 ferrule has been placed onto the
cable, and that the cable braided shield is flared
away from the cable.
Proceed as follows:
4.1. Crimping the Center Contact (See Figure 2)
1. Close the tool handles until the dies are partially
closed.
2. Assemble the center contact onto the cable
center conductor. 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.
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.
