Adequate Construction but TERRIBLE Crimp Holding
on December 3, 2017
I bought these for my typical, everyday need for RJ45 plugs both at work and at home. I've been making these kind of patch cables for 20 years with CAT5/e/6 so I believe it is safe to consider myself an expert on the topic. I had high hopes for these plugs based on their reviews, but after trying out a sampling of the 100 jacks I just received on a stack of CAT5e cables I had piling up that needed new ends on them, I was very disappointed.
The overall construction of these plugs isn't bad at all - they're pretty solid, the locking clips don't appear to break off easily, the teeth seem pretty good and the wire channels inside are easy enough to hit. That said, the one item that is crucial to any effective RJ45 plug, the crimping connection/hold, is terrible.
If you are using a non-plenum cable or patch cord, forget about it, the won't hold more than a few minutes and you can easily wiggle the cable back and forth, which will also cause your individual strands to start moving. The first cable I tested (white non-plenum) showed a SHORT on the tester. As I said, 20 years doing this and I have NEVER received a SHORT error on my cable tester when making a new patch cable. The second cable I made showed that it was connected correctly, however pin 3 was not communicating properly - again, a first in 20 years of making these. I thought at this point it was my cable, so I tried some of my other plugs I've been using for a few months from a different vendor, and sure enough, everything worked fine and tested perfectly the first time around. I can only conclude that, at least with thinner non-plenum cables, the crimp is so weak that the wires won't hold still at all.
I had a bit more luck with the plenum (blue) based cables that I tested with, but only because they are thicker by design because of the plenum coating. Once crimped, the plugs held on to the cables for a bit longer, but after a few seconds of moderate wiggling, sure enough the cable did break free of the crimp too. The only difference here is that the plenum cables DID test out perfectly despite the crappy crimp, but I suspect that is simply because the twisted pair coatings are also thicker and can hold on tighter, for longer, than the non-plenum cables. That said, I simply can't this kind of risk that ANY cable I make or correct could come loose and begin malfunctioning at any time after I make it.
So, bottom line here is that the plug construction itself is adequate, however the crimp connection is TERRIBLE and I highly recommend avoiding these plugs if you want your work to be taken seriously.
