As shown on the picture below, the pins on these Ethernet ports are not all the same.

It looks like pin 3, 5, 7 and 8 (or 1, 2, 4 and 6?) are elevated in order to make contact, but not the others.

I'm seeing this on a RJ45 Cat6 STP wall plug like shown below.

Why is that?

  • On what device are you seeing this?

    I've seen both styles of pins used, but never together. There's no logical reason to mix them, or have that pattern of pairs.

  • The early-contact pins are 1, 2, 4, 6. 1-2 is a pair, but 4 and 6 belong to different pairs. All pins need to be used for Cat 6. Why the pins are staggered is beyond me, likely just mechanical reasons. Both your photos seem to show different jacks though.

  • Blow up the sockets on the 2nd image, and you will not see anything like what is on the first image. Those are two different devices. Even on the first image, the pins that are not raised will make contact when the jack is inserted into the socket. Notice that they are bent up to meet the contacts in the the jack.
