Astrotek CAT5e RJ45 ethernet network LAN cable features 24AWG stranded copper cable with shielded plug at each end. You can be sure that the high quailty jacket of the cable will withstand years of harsh weather, whether in your backyard, around the siding of your house, or in a factory setting. Special metal clad shielded RJ45 connectors. These connectors make ground contacts with the grounded RJ45 sockets on Ubiquiti devices and POE injectors. A Foil Shield surrounding the conductors, and electrically connected to the metal shields on the RJ45 connectors. This provides an electrical path from the circuit board of the device, and the ground pin of the AC cord used with the POE injector. This path prevents voltage build-up during nearby electrical storms that can destroy the ethernet interface on the device. A weatherproof, externally rated jacket.
