So, why the reference to three locations?
As per my previous message, I read that some tools only crimp in two
locations and they don't do a good job as professional tools that
crimp
in three locations.
And that would be in reference to coax connectors, not RJ45.

AMP crimpers (RJ) crimp the connectors in three locations, not two, as
do some of the cheaper crimpers. |

I still don't understand what the 3 points are. There are the contacts,
which are pushed down, the locking tab and ??? |

This may be a patented AMP improvement on RJ plugs.
Their third location is a lock-down bar between the gold
IDC teeth and the cable jacket lock-down bar near the end.
This intermediate point holds conductor insulation tightly and
reduces stress on the gold IDCs when the cable jacket crawls.

Hi,
Can you recommend a good crimping tool for RJ45 plugs under $100?
I'll use it mostly for me and friends, not for professional work.
Thanks.
Wander down to your local electronics shop. There are many consumer
level
crimpers available for well under $100.
As with most things, you gets what you pays for. The inexpensive Ideal
crimper, for example, does not crimp at all three locations. It only
crimps two points, so the wires don't have a firm anchoring as with a
better quality crimper. The Paladin crfimpers were up around a
hundred,
maybe more than that now, and looked pretty sturdy. I don't rememebr
if
they crimped all three points, tho.
A couple points that are important. Some cheap crimpers try to do doo
much, like also crimp RJ-11. They have cut corners, so they do not
seat
the gold plated pins well, so that the teeth don't pierce the wire
insulation fully and make good contact.
Also, you will never get better than cat5 quality cables. Since
currently virtually all contractors are installing cat6, IMHO you will
never get the full channel up to cat6 if you use anything but the best
cripmers that do the special cat6 connectors. And it's also so cheap
to
buy your patch cords premade, with cat6 cable and connectors, so doing
your own crimping is not the best idea nowadays.
|
I have both a nice paladin, around $120, and an Ideal, and i carry the
ideal all the time, lighter, smaller, easier to user, and just all around
better.

That might explain it. I've never worked with AMP plugs, that I'm aware of.

You might easily not notice. AMP plugs work like normal in 2
position crimpers. They fit and crimp fine. The only thing
is the intermediate crmp bar is not locked down.
What doesn't work is trying to crimp other plugs in AMP
crimpers (at least with the 3 position dies). This will
_NOT_ work because the normal plugs have solid plastic where
the dies want to push in.
