Insulation Crimp Note
Due to the terminal’s insulation grip design
and insulation diameter range, this tool uses
overlap form geometry in the insulation
punch. This produces an overlap insulation
crimp (A-620 compliant). Although the
insulation punch profile may appear lopsided,
this is a normal condition for this tool. See
figure to the right. Some tools with multiple
crimp pockets may not have the overlap
profile on all pockets.
CONDITIONS
After crimping, the conductor profiles should measure the following:

To achieve IPC/WHMA-A-620 Class 2 crimps, the following overall wire insulation diameter ranges are recommended:
Profile A:
1.30-1.40mm (.051-.055”)
Profile C:
1.10-1.20mm (.043-.047”)
Profile B:
1.35-1.55mm (.053-.061”)
Profile D:
0.80-1.00mm (.031-.039”)
Tool Qualification Notes
1. Pull force should be measured with no influence from the insulation crimp.
2. The above specifications are guidelines to an optimum crimp.
Note
A crimp height chart is provided with this document as Reference Only. Due to the wide range of
wires, strands, insulation diameters, and durometers available, actual crimp height measurements
may very slightly. An occasional destructive pull force test should be performed to check hand tool
crimp. Pull force value must exceed the minimum pull force specifications listed.
