Procedure
Step 1 Hold the crimped connector, with the front side facing you, and check whether the contact strips
are of the same height. The height should be 6.02 ± 0.13 mm (0.237 ± 0.005). If a measuring
tool is not available, you can compare the connector with a standard connector.

Issue 02 (2011-09-10)
To ensure proper contact between the crimped wires and the wire conductors, the heights
and sizes of the contact strips must be standard and the same.
The contact strips must be parallel to each other, with an offset less than 5°. The top margin
of a strip must be parallel to the axis of the connector, with an offset less than 10°.
To ensure conduction, the surface of the contact strips must be clean.
The contact strips must be in good contact with the RJ45 socket. The plastic separators
must remain intact and be aligned.
The contact strip blade must extend beyond the ends of the wires. The ends of the wires
must be in contact with the edge of the RJ45. The distance between them must be less than
0.5 mm (0.02 in.).
NOTE
All unqualified pieces must be crimped again.
