7. INSPECTING THE CRIMP HEIGHT
Crimp height inspection is performed using a micrometer with a modified anvil, commonly referred to as a
crimp-height comparator. TE Connectivity does not manufacture or market crimp height comparators. Detailed
information on obtaining and using crimp-height comparators can be found in instruction sheet 408-7424.
1. Refer to Table 1 and select a wire (maximum size) for each crimp section listed.
2. Refer to section 5, CRIMPING, and crimp the contacts accordingly.
3. Using a crimp height comparator, measure the wire barrel crimp height listed in Table 2.
If the crimp height conforms to that shown in the table, the tool is considered dimensionally correct.
If not, adjust the tool. Refer to section 8, ADJUSTING THE RATCHET.
CAUTION
Do not use damaged product. If a damaged contact is evident, replace it. Do not re-terminate contacts.
