Most balun/extender mfgrs. state that use of EZ connectors is not recommended or supported. They end up being forbidden at any company I work for. Whenever I see them I think to myself, "I bet those were made for electricians trying to do LV".

I've been using one-piece RJ-45 connectors since I started & they're cake for me. I bet my rate of crimping a bad connection is less than 1 in 250, and that's being conservative.

Most manufacturers understand that the termination is only as good as the terminator, so they cover their a$$ by saying they do not recommend certain things, especially ones that are easy to do wrong (EZ connectors would fall into this category....I think among others, Brent has explained several times the why and how). As with any other termination, EZ connectors work fine up until the time they do not work. And usually, the reason they do not work is because some dummy did it the wrong way and/or with the wrong tools. I knew an installer who only crimped his radial RG6 connectors halfway because "it was too hard" to crimp the things down all the way.

I do not use EZ connectors. Neither place I have worked for has used them for whatever reason....and it was not due to HDMI extenders since we did not use them since long before HDMI was even invented. :) I have an astounding success rate with the one piece RJ45 connectors as well. And with the 2 or 3 piece CAT6 connectors also. But I would seriously consider using 1 piece CAT6 EZ connectors if I were doing a million CAT6 terminations. My thumbs hurt after 20-30 of the Binary 3 piecers. :P

Well at least provide us with links to these policies so we have them documented.

Thanks.

EZ RJ's when it's for something other than an a HDMI extender.

In the case of a HDMI extender it's the single piece conventional RJ's for me, because I want to know that it's going to work.

Any reason to believe HDMI extenders require something special?

EZs are pretty much the same as your typical RJs.

No they are not. The have extra length of wire that extends beyond the blades in the connector. This has been discussed many times as the reason they are not acceptable to use for extremely high speed networks (10 Gigabit).

HDMI extenders are 10 Gigabit speeds. There is no network you probably work with in a home that is using that speed. So EZ connectors can be used with regular network, up to Gigabit networks. But when you get up into speeds with 10 Gigabit, EZ connectors can cause issues.

While I am in no position to disprove your statement as a general rule, I've installed multiple HDBT tranceivers using either Belden 7851a or Belden 1872a bonded pair cable with EZRJ45 CAT6 connectors and have not had any issues at 1080p/60 HD resolutions [big knock].

Most manufacturers recommend NOT using EZ45's including us. The long term results will largely depend on the environment that the product is in. High humidity environments will be susceptible to corrosion on exposed ends. If the corrosion becomes significant there is a likelihood that the corrosion could create a bridge between wires and cause problems.

NEVER recommended for outdoor installations.

I just terminated some CAT6 cables at my house. What a PITA. After doing some of these I really began to see the desire to use EZ45's.

The next time a customer thinks your bid is too high, give him or her a 1 foot length of CAT5, tell them to correctly terminate both ends. Come back in an hour and let them know you will have to do this 50 or 100 times for their project. Now what do you think about the price?

I to have used EZ45 connectors with HDMI extenders (and it was even regular cat5) and it worked. But the 1st one that failed on me and replacing the ends with some AMP cat5 connectors fixed the problem; I researched and learned what was wrong with using EZ45's. I have never used them since on HDMI extenders.

Ain't that the danged truth...

The HDBaseT org states that no special cabling is required and the technology will work over cat 5e/6.

Given the spec of 100m max cable length I find it hard to believe that the little bit of wire beyond the contacts (and it is a little bit - maybe 1/32) is going to have a significant impact.

The issue with corrosion is of greater concern.

And the fact that replacing one kind of an connector with another in one situation which then worked is hardly a statistically meaningful event. You might have used the same kind of connector and had the same result. There are many other variables in play beyond the kind of connector used.

Learn how to terminate a proper RJ 45 end.. Eazy ends are for lazy people that can't be bothered with doing it the right way and would never be accepted in any installation that required any kind of certification.

this thread is crazy and full of random unproven info.

The ends are fully TIA compliant and definitely would certify. In fact I have read of research that they have the potential to work better by requiring less wire to be "untwisted". you can pull the twist tight up into the connector.

IMO, the manufacturers advice of not using EZ was based on previous HDMI extender technology which was finicky at best. why not advise a method that eliminates one possible point of failure? Be it the actual connector or un-sharp tool.

I have NEVER had a failure related to EZ connectors on any of our HDBASET equipment. EVER, not one. We terminate them perfectly, cleanly, as good as a termination you can get with EZ connectors. When done so, they are absolutely in spec. I have terminated 10s of thousands of standard Cat5e and 6 connectors in 15 years, Trust me, I know how to them well! My fingers and hands have definitely been affected by this. I use EZ for that reason alone. Until they present a problem for me, I will continue to use them. That being said, I do have 50 of each 5e and 6 standard connectors for emergency. I know there are 50 because that is the quantity i bought them in and we havent used one.

That being said, we barely use them anyway, we patch everything at the rack and rarely would we not have a wallplate. We use ICC Cat6a keystones at both ends.
I love supporting product that supports me!

I switched to EZ's primarily due to a Belden representative's conveyance of this superior aspect of the EZ's...Better preservation of pair twists (on average) and, thus, superior noise rejection and performance (on average).
