NECABLES 2Pack 6 Inch Short RJ12 Cable Short Telephone Cord Phone Cable

I've bought these cables from the same vendor several times over the past few years, and they've worked perfectly for my applications (connecting between a PLC and an HMI). This week, I needed another for a similar application, but this time I was careless and chose incorrectly between "straight" and "reverse" wired. I'd built up the panel on my bench, testing it with my one remaining old cable, and it worked perfectly. The new ones I ordered were three feet instead of two - this was the supposed to be *only* difference. After installing the panel in the field (actually, my RV) with the new cable, it didn't work. Well crap, I must have blown something out - that's not good! After futzing around with it for a couple of hours upside down in a compartment, I bypassed the system and gave up for the night. The next morning, I realized that it had to be the cable, and I had a suspicion why... Crawling back into the compartment, I unbolted everything (why did they put the frickin' connectors on the bottom??), and pulled the cable. Upon comparing it to the older one, I could see that the vendor's definition of "straight wired" was different than I was accustomed to. You can see this in the picture (sorry it's a bit blurry - dammit, Jim, I'm an engineer, not a photographer). The older cable is on the left, which despite the conductors being in reverse order is what I would consider to be straight wired. This is because if you lay the cable out flat and straight, the conductors do indeed run in a straight line from one connector to the other. Note that the Bell company also considered this to be straight wired... Now look at the other (new) cable. Here you can see that the conductors are the same going into both connectors, such that if you laid the cable out straight and flat, one of the connectors would now be upside down. It's counter-intuitive, but this is actually considered to be a "swap" or "reverse" cable. Most telephone equipment would never notice the difference, because land-line wiring got screwed up so frequently after the Bell break-up that nearly every piece of telephone gear is tolerant of reverse polarity. However, if you're actually going to use these cables for data (as advertised), make sure you choose correctly; a "standard" 6P6C cable is the one this vendor call "reverse wired". In my case, I just cut off one end and crimped a new connector on the correct way, but there are a few hours and a couple of barked knuckles I would rather have not spent. Assuming you do get the correct wiring, these cables seem to use decent cable, and were well put together - I've never had one fail in the frequently rough places I've used them. It's also nice that they're available in a wide variety of lengths, or even custom, and with either wiring, They definitely deserve the five-star rating.

Bought these because I needed a longer rj12 for my moza Sim racing setup. Works perfectly. Length is what I ordered and feels like a better quality cable than what came with my handbrake.

I bought this for my Spider Farmer grow tent accessories and it works flawlessly. They are much better made than what come with the AC5 power strip and are the length I needed for my 3x3 tent. They connected up to my Spider Farmer Fan. I would buy again for the price and quality.

They worked just fine for what I needed

Love em

Good, thick, heavy-duty cables. Just what I needed for my project.

If you're looking for a replacement for your FT-891 Yaesu HF transceiver, THIS IS THE ONE. Beware of "twisted" cables, you need MALE TO MALE STRAIGHT RJ12 cables, no longer than 6 inches in length. This one was perfect.

I bought these cables to support additional EXT devices on my Pegasus astronomy programmable USB controllers. I needed short cables and these fit the bill nicely, keeping cable run lengths short as possible. These cables appear well made and so far no issues.

good quality, did the job

works fine, no issues. I ordered an extra short cable to make a tidy install.

Good quality and value.

Fast delivery and does the job perfectly
