Black Box 20ft CAT6 250MHz Shielded Ethernet Patch Cable (Blue)

The Black Box EVNSL0272BL-0020 is a 20 foot Ethernet patch cable that complies with the CAT6 specification and arrives in blue for quick identification in crowded racks or workstations. Built for sites where electronic noise can cripple network speed, it surrounds each of its four twisted pairs with foil and then adds a braid made of tinned copper, forming a shield that blocks electromagnetic and radio-frequency interference.

Certified for 250 MHz, the cable moves Gigabit Ethernet, Fast Ethernet, and voice or audio video traffic without hesitation. Each RJ-45 plug uses 50 micron gold plated contacts that resist corrosion and maintain solid conductivity. The molded strain relief protects the latch, and the connector assembly is verified for up to 750 plug-and-unplug cycles, so it stands up to frequent reconfiguration in patch panels or equipment racks.

Choose this cable when you route lines near fluorescent fixtures, power supplies, or other gear that can inject noise into unshielded cabling. It fits naturally in offices, data center cabinets, broadcast suites, test benches, and home networks where reliable, high-throughput links are essential.
