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

Overview

The Black Box EVNSL0272GN-0020 is a 20-foot CAT6 shielded Ethernet cable designed to maintain reliable Gigabit Ethernet speeds in environments with significant electrical noise. Rated for 250 MHz, it supports high-speed data, voice, and video transmission with minimal interference. Its green jacket makes it easy to identify among other cables, simplifying maintenance and troubleshooting.

Key features

• Double shielding with individually shielded twisted pairs and a tinned copper braid reduces electromagnetic and radio frequency interference, ensuring clean signal transmission.
• 50 micron gold-plated RJ45 contacts provide excellent conductivity and resist corrosion, supporting up to 750 insertion cycles for long-lasting use.
• Molded strain relief at connectors prevents sharp bends, enhancing durability and reducing cable damage over time.
• 20-foot length is ideal for connecting racks, desks, or wall plates without excess slack or tension.
• Green jacket color helps quickly trace and identify the cable in complex network setups.
• Compatible with any standard CAT6 or lower network port, allowing seamless integration with existing infrastructure.
