The difference between 110 connect and LSA+

There are two versions of IDC contacts around: 110 connect and LSA+. At first glace they resemble each other, but they differ in important details. Read on to find out the differences between the two IDC types and why one shouldn’t mix the punch-down tools.

Insulation displacement contacts (IDCs) of RJ45 outlets, modules and patch panels are available in two versions: 110 connect and LSA+. It is not too difficult to tell the two apart:

With 110 connect, the IDCs are arranged vertically to the wire, with LSA+ they are arranged at a 45 degree angle. This ensures a much better and stonger contact.
