Super Handy RJ45 Connectors
 

There are probably some folks on here that do their own wire/coax/fittings and a month ago I found a couple of my RJ45 connectors had lost their connectivity due to old age, dust, corrosion or ??? since the wire they were on was about 40 feet long I really did not want to have to run new wire. So I needed to put on new RJ45 connectors which if you have done this it is a real pain since there are 4 pairs of wires I.E. solid color and a white wire with a matching color stripe. Once you strip off the outer cover then separate the pairs you have to straighten the wires and try to wiggle them in the right order which is not easy. BUT I found some new fangled RJ45 connectors that let you push the wires in so they pop out the end so you can see their order!!!!! Hot damm, that makes installing new connectors way easier and no chance of getting the wires mixed between the ends. Of course they came from Amazon!

That reminds me of my old Ma Bell job. We had colored pairs of wires in bundles that were also color paired. So you would open a cable boot look for the blue/white bundle then inside that bundle look for a red /green pair. So fun with a flashlight in your teeth while hanging onto a pole with sharpened hooks strapped to your legs. All for $98 / week.

Once you go with the EZ-crimp style ends, you'll never go back. Only annoyance is that you need the special crimper tool that cuts the ends off, you can't use your old tool.

White, Red, Black, Yellow, Violet
Blue, Orange, Green, Brown, Slate

I have an old crimper and connector set for RJ45 and making my Cat 5a and 6 cables. It has a little sleeve that holds the wires in the proper order, and then I slide the plastic connector over them, and crimp. Then I have a tool that checks the connections with blinking lights.

I decided after running all the Cat 5A POE cables for my security system I do not want to do that for a living!

I would love to see the rig real professional use. It has to be better than what I was using. Mine worked, but it took me forever.

I need to do this. I bought the connections but not the tool. All I have for tools is coax.

How many wires you cramming in there?

WhtOrg, Org, WhtGrn, Blue, WhtBlu, Grn, WhtBrn, Brn

I did the ends for about 95 IP cameras at work, usually either on top of a 12 foot ladder or in a manlift, 15 feet in the air. I DO NOT LIKE HEIGHTS. Wired them all by headlamp because they were above the dropped ceiling lights.
Then fixed the punchdown on about 40 of them.
Then added 15 or so new Ethernet runs through the building, and terminated both sides.
Then 30 doors with RFID readers, 2 cables per door terminated on both ends.

Then tested all of them with a Fluke CAT6 verification tool.

Honestly, the company in the building that does building network installs has us train interrns using a Platinum Tools crimper by hand. It's still the fastest way since there's so much manual work needed per end (untwisting the pairs, stripping the jacket,etc). And, you still need to visually check the order before crimping. So, a powered machine of some type really won't save any time.

Those are the primary and secondary color groupings of a 25 pair cable.

The connectors I bought off Amazon (of course) came with a new type of stripper/crimper and I think 50 connectors. Works really great, of course Harbor Freight sells that stuff too.

B spec is the colors you quoted. Why is there an a spec and why use it?

A spec was older.

B spec has a better choice of wires side by side in the connector to deal with electrical fields. High speed data now creates some wild electromagnetic fields when two wires are next to each other transmitting data, the A-spec couldn't handle that very well.


For low-speed networks, or power only type things, it doesn't matter what order you choose as long as both sides are the same, but if *you* ever work on a cable, then in a year someone *else* does, they're going to assume that you used the B spec.

This. And if you want to use some standard commercial Cat6 cables of today, everything works well together. The biggest thing is no cable is forever. It will be worked on again, and if it is built with a standard, much easier for the next guy. And the next guy may well be yourself trying to figure out why one cable is slow or not functional.
