Norden Category 6 tool less UTP keystone Jacks give optimum protection from electromagnetic interference from an outside source. The tool-less termination allows all eight conductors to be terminated simultaneously when the termination cap is pressed into place. These PCB based Jacks are designed to reduce the Insertion loss & alien cross talk in order to provide maximum flexibility and high performance for all 10G Ethernet applications in accordance with IEEE 802.3an and are available in a 180° orientation with back interconnection of Dual Style IDC blocks in universal pin/pair assignment.180° orientation provides perfect termination with minimum distance to the IDC. This is tested to 250 MHz range over 100m and supports T568 A&B wiring & easy installation. The jack is manufactured with an integral cable strain relief. They can be installed into a number of Face plates and unloaded shuttered modules.
