I've been trying to first identify and then try to find and purchase different types of RJ45 jacks. There are a few cases that I'm considering and I'll lay them out here for you based on the cable they will be crimped on.
1. Cat5 - Stranded
2. Cat5 - Solid
3. Cat5e - Stranded
4. Cat5e - Solid
5. Cat6 - Unshielded Stranded
6. Cat6 - Unshielded Solid
7. Cat6 - Shielded Stranded
8. Cat6 - Shielded Solid
These are the 8 cases that concern me in my line of work.
I separate Stranded wires from Solid wires because I once came across the connector in the photo below (RJ45-Solid) but I can't find it anymore. Notice how the blades are slightly curved to allow them to attach to the sides of the solid wire instead of cutting through it. Which would be the case if one used the other jack (RJ45-Stranded) who's blades are straight.
In the case of a Cat5e cable, I keep seeing these connectors on ready-made patch cords. Instead of having the wires lined up on a straight line, they are positioned in two rows, one higher, one lower. (See picture RJ45-Cat5e)
I was able to find some connectors for Cat6 cable, seeing as there's very little space to fit a Cat6 cable in the Cat5 connectors.
Any help identifying these connectors would be appreciated.
