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

Overview

The Black Box EVNSL0272BL-0020 is a 20-foot shielded Ethernet patch cable designed to deliver reliable network performance in environments prone to electromagnetic interference. Certified for frequencies up to 250 MHz, it supports Gigabit Ethernet, Fast Ethernet, and audio/video traffic with stable and consistent connectivity. Its blue jacket makes it easy to identify among other cables in busy racks or workstations.

Key features

• Shielding on each twisted pair combined with an overall tinned copper braid reduces electromagnetic and radio-frequency interference, ensuring signal integrity in noisy environments.
• 50 micron gold plated RJ-45 contacts resist corrosion and maintain low resistance connections for long-term reliability.
• Connector assembly is tested to withstand up to 750 insertion and extraction cycles, making it suitable for frequent reconfiguration in patch panels or equipment racks.
• Blue jacket color aids in quick cable identification and organized cable management.
• Supports multiple network protocols including Gigabit Ethernet, Fast Ethernet, voice, and audio/video signals for versatile use.
