While I've only used passthrough connectors, it seems that non-pass through connectors would be much less forgiving. With pass through, the wires don't have to be an exact length and they don't all have to be the same length to each other. Once you push the wires through the connector, it is also very easy to double check that the wires are in the correct order before you crimp the connector.With non-pass through, it is harder to verify the order of the wires because you have to try to look through the connector housing to see the order of the wires.I would definitely recommend pass-through from someone that has to start from scratch and buy a crimper and connectors. The crimpers are unique to the style of connector, so you'll have to pick one style and stick with it.
we aim to provide our customers with the best options to make their job easier. One part in particular that our customers request daily is RJ45 connectors. Recently we have received a lot of questions asking what the better RJ45 connector to use is between the non pass-through and pass-through connectors.
Before we break down the differences between these connectors, let's take a look at what they have in common. The pass-through and non pass-through RJ45 connectors are available for Cat5e, Cat6, and Cat6a cabling. You also have the option of shielded or unshielded versions of either connector style. Please be aware that some shielded connectors have an external ground while others are internal.
Hopefully, you now have a better understanding of how the connectors are similar and how they differ. With this information, we hope you are ready to decide which is the better option for your application!
