Black Box CAT6 25ft Shielded Ethernet Cable (Black)

Overview

The Black Box EVNSL0272BK-0025 is a Category 6 shielded Ethernet cable designed to maintain reliable network connections in environments with significant electromagnetic interference. At 25 feet long, it provides a direct link between switches, routers, servers, or Power over Ethernet devices without the need for couplers that can degrade Gigabit Ethernet performance. Its robust shielding and flame-retardant jacket make it suitable for both indoor and outdoor installations, including challenging spaces like manufacturing floors and broadcast studios.

Key features

• Dual-layer shielding with aluminum mylar foil around each twisted pair and a tinned copper braid around the entire cable reduces radio-frequency noise and electromagnetic interference.
• Flame-retardant black PVC jacket supports safe routing through ceilings, exterior walls, and outdoor areas while meeting common safety standards.
• RJ-45 connectors feature 50-micron gold plated contacts that resist wear and maintain low resistance through up to 750 insertion cycles, ensuring long-term connection stability.
• Factory tested to 250 MHz bandwidth, providing reliable support for Gigabit Ethernet speeds with extra headroom for demanding network traffic.
• Compliance with RoHS, EN 50173-1, IEC 60332-1, and ISO/IEC 11801 standards guarantees quality and safety in regulated environments.
• Lifetime limited warranty from Black Box offers confidence in durability and performance over time.
