This RJ45 Connector only supports Cat7 Cat6A installation . Support inner conductor 23 AWG;The Insulated core diameter must be 1.35-1.45mm thick. Otherwise, this can cause the cores in the connector or threading aid to not be fixed and moved in them.High speed signal transfer rate This Cat 7 connector also supports higher data transfer rates up to 10 Gigabit EthernetPass Through type RJ45 crimp connector: the order of wiring can be double checked by the pass-through design of the connector. Thus, the assembly process is much easier than the conventional type, which can reduce the error rate. Professional RJ45 crimping tool is required for this.Material and performance: Shielded RJ45 connector Cat7 Shielded housing: copper alloy; Contact plate: copper alloy, thickness of gold plating: 50u; reduce signal interference; Durable material for easy plugging and unplugging; leads to increase the quality of signal transmission.
