ECF504 Ethernet Cat6 Coupler Kits

L-Com ECF504 Ethernet Coupler Kits offer Cat6 performance ratings that facilitate high-speed data communication. These adapters feature fully stamped shielding that provides isolation from both EMI and RFI, ensuring smooth operation. The panel-mount RJ45 coupler kits allow panel mounting in virtually any panel thickness, and they are designed to work with EIA/TIA 568A and B wiring, providing a passage for high-speed data communication through a chassis or rack panel. L-Com ECF504 Ethernet Cat6 Coupler Kits are suitable for telecommunications, LAN, IDF, and voice and data applications.
