Procedure
Step 1 Hold the crimped RJ45 connector and observe the side from the front. Check the
height of each metal contact slice. The standard height is 6.02 mm ± 0.13 mm. If
no special test instrument is available on site, compare the RJ45 connector with
another well crimped RJ45 connector.
unqualified RJ45 connector and a qualified RJ45 connector respectively.
Issue 05 (2023-03-31)
The metal contact slices should be of the same height and are of the required
sizes. The crimp part should properly contact the core conductor.
The metal contact slices should be basically parallel with a deviation of not
more than five degrees. The top edges should be basically parallel with the
axes of the RJ45 connector with a deviation of not more than 10 degrees. This
ensures reliable contact.
No perceptible object, dirt or rust should be present on the surface of the
metal contact slice. Otherwise, the conductivity is affected.
The metal contact slices should reliably contact the RJ45 connector socket.
The plastic spacers should remain the same before and after the crimping,
and should have the same spacing between each other. Each of them should
be straight and intact.
The crimping blade of the metal contact slice should exceed the core end. The
core end should tightly contact the trunking side of the RJ45 connector. The
contact spacing should not exceed 0.5 mm.
