2. Slide the ferrule forward over the braid until the
ferrule is against the connector body.
3. Place the ferrule in the crimping chamber on the
anvil die so that the shoulder of the connector body
is against the edge of the die. Refer to Figure 4.
4. Holding the assembly in place, close the tool
handles until the ratchet releases.
5. Allow the handles to open fully, and remove the

5. INSPECTION
5.1. Visual Inspection
The crimping dies should be inspected on a regular
basis to ensure that they have not become worn or
damaged. Inspect the crimping chambers for
flattened, chipped, worn, or broken areas. If damage
or abnormal wear is evident, the tool must be
replaced. See Section 8, DIE REPLACEMENT.
5.2. Periodic Inspection
A. Center Contact Crimp Height Inspection
This inspection requires the use of a micrometer with
a modified anvil as shown in Figure 5. Tyco
Electronics recommends the modified micrometer
(Crimp Height Comparator RS–1019–5LP), which can
be purchased from:
Proceed as follows to check the crimp height of the
center contact:
Shearer Industrial Supply Co.
1. Select the center contact for the connector.
2. Refer to Section 4, CRIMPING PROCEDURE,
and crimp the center contact accordingly.
3. Using a crimp height comparator, measure the
crimp height as shown in Figure 5. If the crimp
height conforms to that shown, the die assembly is
considered dimensionally correct. If not, return the
dies to Tyco Electronics for evaluation and repair
(refer to Section 8, DIE REPLACEMENT).
