Networking Cable EFB Elektronik K8104SW.20 RJ-45 Cat6 20 m Black

The EFB Elektronik K8104SW.20 RJ-45 Cat6 networking cable is a 20 m black cable designed for wired Ethernet connections where stable, high-speed data transfer is required. Built to Cat6 specification with U/UTP construction and gold-plated contacts, the cable supports data rates up to 5000 Mbit/s and is suitable for typical office, home or server-room deployments that use RJ-45 terminated Ethernet ports.

Advantages

This Cat6 cable offers U/UTP shielding which helps reduce external electromagnetic interference in typical indoor installations. Gold-plated RJ-45 contacts improve contact reliability and reduce oxidation over time for consistent signal transmission. The 20 m length provides flexibility in device placement without the need for additional patching, and the black jacket gives a discreet appearance that integrates with most cabling setups.

Suitable for

• Connecting desktop computers, switches and routers in offices and homes
• Patch connections in network cabinets and server rooms
• Wired connections for IP cameras, VoIP phones and media devices
• Temporary or permanent Ethernet links for multimedia streaming and data transfer

Key specifications

• Cable category: Cat6
• Cable construction: U/UTP (unshielded twisted pair with overall braid absent)
• Maximum data rate: up to 5000 Mbit/s
• Length: 20 m
• Connectors: RJ-45 to RJ-45
• Contact plating: gold-plated contacts
• Color: black

How to use

Plug one RJ-45 connector into the Ethernet port of your device and the other into the switch, router or wall outlet designed for network access. Ensure connectors are fully inserted until the latch clicks to establish a secure physical connection. For best performance, avoid excessive bending or kinking of the cable and maintain recommended separation from strong electromagnetic sources such as large motors or fluorescent ballasts.

Recommendations

For stable network performance, route the cable away from power lines and high-interference equipment. Use cable management accessories to prevent strain on connectors and to maintain signal integrity over the full 20 m length. Test connections after installation with a network tester if precise diagnostics are required.
