Networking Cable EFB Elektronik K2793.1 Red 1m Cat5e SF/UTP

The EFB Elektronik K2793.1 is a 1 m Cat5e SF/UTP crossover patch cable designed for Gigabit Ethernet at up to 100 MHz. The cable uses 4 pairs of AWG26/7 conductors with foil and braid shielding and terminates in two shielded Hirose TM11 RJ45 plugs (IEC 60603-7-3). The outer sheath is low-smoke, halogen-free (LSZH) and the cable meets flame-retardant and smoke/halogen standards for installation safety.

Advantages

The SF/UTP construction with foil and braid shielding reduces electromagnetic interference and crosstalk, supporting stable Gigabit data transmission. Using shielded Hirose TM11 RJ45 plugs ensures secure, reliable connections and compliance with IEC connector standards. The LSZH sheath minimizes hazardous gases and smoke in the event of a fire, while the mounted red strain relief improves durability of the connector junction.

Suitable for

• Cross-connecting network devices that require a crossover connection (e.g., direct device-to-device links)
• Environments needing reduced interference — installations near electrical equipment or cabling
• Indoor installations where low-smoke, halogen-free materials are required

How to use

Plug each Hirose TM11 RJ45 connector into the corresponding RJ45 socket on the devices you intend to link. Because this is a crossover cable, connect devices that require direct peer-to-peer wiring (for example, certain switches or legacy network interfaces). Ensure connectors are fully seated and strain relief is positioned to reduce mechanical stress at the termination point.

Recommendations

Use this cable for short-distance, indoor cross-connections up to 1 m. Avoid sharp bends and protect the cable from crushing or prolonged exposure to heat. For longer runs or different wiring needs (straight-through), select the appropriate category and wiring type.
