Cavo di rete EFB Elektronik K8449.5 grigio 5 m Cat5e F/UTP

The EFB Elektronik K8449.5 is a 5 m Cat5e F/UTP crossover networking cable with shielded RJ45 connectors (Hirose TM11) designed for 1 Gigabit Ethernet at 100 MHz. The cable uses four twisted pairs (AWG26/7) with foil shielding and a PVC jacket, and it meets flame retardant and low-smoke, halogen-free standards for safer installations. The grey cable is fitted with a mounted red strain relief (without latch protection) to reduce cable stress at the connector.

Advantages

This Cat5e crossover cable provides reliable 1 Gigabit Ethernet connectivity and supports 100 MHz bandwidth. The F/UTP construction (foiled overall) reduces electromagnetic interference compared with unshielded cables. Shielded Hirose TM11 RJ45 plugs (IEC 60603-7-3) ensure robust connector shielding. The cable complies with IEC 60332-1 (flame retardant), IEC 60754-2 (halogen-free), and IEC 61034 (low smoke) safety standards.

Suitable for

• Direct device-to-device connections requiring crossover wiring (e.g., switch to switch, PC to PC where crossover is needed)
• Home and office Ethernet networks supporting Gigabit speeds
• Installations needing shielded cabling to reduce interference

How to use

Connect each end of the cable to the RJ45 ports of the devices you want to link. As a crossover cable, it swaps transmit and receive pairs, so use it for direct connections where crossover wiring is required. Ensure connectors are fully inserted; the mounted strain relief helps prevent abrupt bending at the plug. Avoid excessive twisting or pulling on the cable during installation.

Recommendations

For best performance, keep the cable away from strong electrical noise sources and avoid tight bends below the cable's minimum bend radius. Use this crossover cable specifically when connecting devices that require crossed pairs; for standard connections between devices via a switch, use a straight-through Cat5e or higher cable.
