REASONS WHY IT'S HARD TO MAkE
GOOD CRIMPS ON Rj45S (Continued)
expensive, solidly made crimping tools did not make good
crimps . The best and recommended crimper is provided
in the LC&D Crimping Kit . This crimping tool has no "stop"
feature . The no "stop" feature allows "over-crimping"
to ensure the wires are seated correctly; and thus it is
possible to get the center contacts properly engaged .

THE RIGHT MODULAR CONNECTOR

After much research, we found a modular connector that is
easy to setup and makes it possible to crimp a perfect Cat . 5
cable every time . The brand is "EZ RJ45" (shown in figure
1 . 1 1) . It allows for faster terminations and is compatible
with our crimper tool .
The EZ RJ45 crimp has holes in the front of the connector
which allow the 24AWG wire to protrude from the end
prior to crimping . (shown in figure 1 . 1 1) This will ensure
proper wire color arrangement and will also ensure that
the wires will be pushed all the way into the end of the
RJ45 connector .
Figure 1.11
The "EZ RJ45 Crimping Tool" (shown in Figures 1 . 1 2a and
1 . 1 2b) is specifically designed for these connectors and
will cut through the excess wires protruding from the end
of the RJ45 connector when crimped down .
It has some professional features such as the large crimp-
ing head but it is not capable of "over-crimping" to ensure
that the center conductors have really been engaged .
Though this crimper is very convenient; it will NOT make
good crimps . Use only the ratcheting crimper provided in
the LC&D Crimping Kits . Thus it may ONLY be used as an
initial crimper/cutter and then give the crimp multiple hits
with our recommended ratcheting crimper .
One can use the "EZ-RJ45" connectors with any crimper . It
just requires that the excess wire is cut off very close to the
end of the connector; this can be done with flush cutters .
Care must be taken to
prevent any excess wire
protruding from the end
of the connector since
this will prevent the
connector from seating
properly in the jack .
There are two wiring
standards used for mak-
ing Cat . 5 cables; 568A and 568B . Either one may be used,
as long as it is consistent along the bus . This manual refer-
ences the 568B convention in the examples and images .
