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 dies must be replaced. See Section 8, DIE REPLACEMENT.
5.2. Periodic Inspection
Center Contact Crimp Height Inspection
This inspection requires the use of a micrometer with a modified anvil as shown in Figure 5.
NOTE
Crimp height inspection is performed through the use of a micrometer with a modified anvil, commonly referred to as a crimp
height comparator. TE does not market crimp height comparators. Refer to Instruction Sheet 408-7424 for detailed information
on obtaining and using a crimp height comparator.
Proceed as follows to check the crimp height of the center contact:
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
TE for evaluation and repair (refer to Section 8, DIE REPLACEMENT).

Gaging the Ferrule Crimping Chamber
This inspection requires the use of a plug gage conforming to the dimensions in Figure 6. TE does not
manufacture or market these gages. To gage the ferrule crimping chamber, proceed as follows:
1. Close the jaws until the dies have bottomed, then HOLD the frame handles in this position. Do NOT
force the dies beyond initial contact.
2. Align the GO element with the ferrule crimping chamber. Push the element straight into the crimping
chamber without using force. The GO element must pass completely through the crimping chamber.
3. Align the NO-GO element and try to insert it straight into the same crimping chamber. The NO-GO
element may start entry, but must not pass completely through.
4. Repeat Steps 2 and 3 for the insulation ferrule section of the crimping chamber.
NOTE
Insert the gage element for the insulation ferrule section into the back of the crimping chamber. The GO element for this
section will not pass completely through the crimping chamber.
