Networking Cable EFB Elektronik K8048PUI3 RJ-45 Cat6a 3m Black Red

The EFB Elektronik K8048PUI3 is a 3 m Cat6a RJ45 patch cable designed for 10 Gigabit Ethernet connections. Manufactured in Europe, the cable combines a Cat.7 core (UC900 SS27 Cat.7 PUR from Draka) with TM21 RJ-45 connectors from Hirose and features a highly abrasion-resistant PUR outer sheath that provides resistance to mineral oil and ASTM oil. The cable is intended for stable high-speed data transmission in professional and industrial environments and supports data rates up to 10000 Mbit/s.

Advantages

This Cat6a patch cable offers S/FTP-like construction and high-quality components that ensure reliable 10 Gigabit performance. The gold-plated RJ-45 contacts provide good conductivity and corrosion resistance, while the anti-kink grommet prevents cable damage near the connector. The PUR outer jacket increases durability and chemical resistance, and the assembled construction with TM21 connectors ensures consistent termination quality.

Suitable for

• 10 Gigabit Ethernet networks (10GBase-T)
• Server rooms and data centers
• Industrial and factory networks exposed to oils and mechanical wear
• Office LAN connections and high-speed workstations

Key specifications

• Standard: Cat6a (based on Cat.7 core components)
• Length: 3 m
• Connectors: RJ-45 to RJ-45 (TM21 from Hirose)
• Conductor: 4 x 2 x AWG27/7
• Sheath: PUR, abrasion-resistant, mineral oil and ASTM oil resistant
• Temperature range: -35°C to +75°C
• Max data rate: up to 10000 Mbit/s (10G)
• Colour: Black and Red

How to use

Connect one RJ-45 end to your network device (switch, router, NIC) and the other end to the corresponding port. Ensure connectors are fully inserted until the latch clicks to secure the connection. Route the cable to avoid sharp bends and excessive pulling; the anti-kink grommet helps prevent strain at the connector. For optimal performance, use within specified temperature range and avoid close proximity to strong electromagnetic interference sources.

Recommendations

For sustained 10G performance, verify device compatibility with Cat6a cabling and avoid running the cable parallel to high-voltage power lines. Inspect connectors periodically for contamination and make sure the cable is not bent beyond recommended bend radius. Replace the cable if the sheath or conductors show visible damage.
