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. Figure 1 shows an unqualified piece, and Figure 2 shows a qualified piece.
All unqualified pieces must be crimped again.
