What's the difference between cat5 & 6 PLUGs?

[CSCO10662744_2]

I thought all the connectors are the same, but apparently there's a different kind for cat 6 cables.

What's the difference and which one should I get??

We're running cat6 cables so logically we'd opt for the cat6 plug.

However, most of them come w/ a separate insert that guides the cable ends into the plug.

we've run into problems w/ those types of plugs before - they don't crimp well and we'd get signal loss.

The physical dimensions of Cat 6 RJ-45 plugs and jacks are identical to Cat 5 and 5e plugs and jacks. They are backward compatible with Cat 3, Cat 5, and Cat 5e plugs and jacks.Cat 6 follows the standard 568A.you can opt for cat6 plugs
