Networking Cable EFB Elektronik K8449.2 2m Cat5e F/UTP

The EFB Elektronik K8449.2 is a 2 m Cat5e F/UTP crossover patch cable designed for Gigabit Ethernet connections. It uses foil-shielded twisted pairs and shielded Hirose TM11 RJ45 plugs to reduce electromagnetic interference and ensure stable data transmission. The cable is flame retardant and low-smoke, halogen-free, and comes with a mounted red strain relief without latch protection.

Advantages

This Cat5e F/UTP crossover cable provides reliable 1 Gigabit Ethernet performance up to 100 MHz and improved immunity to interference thanks to foil shielding. Shielded Hirose TM11 RJ45 plugs (IEC 60603-7-3) offer secure metal shielding at the connector ends. The cable’s construction with AWG26/7 conductors and a 5.4 mm diameter balances flexibility and durability. Safety properties include flame retardance (IEC 60332-1), low smoke emission (IEC 61034) and halogen-free materials (IEC 60754-2).

Suitable for

• Direct device-to-device connections requiring a crossover wiring (M:N peer connections)
• Home and small office Gigabit Ethernet links
• Environments where reduced electromagnetic interference is needed

How to use

Connect each RJ45 plug to the corresponding network ports on the devices you want to link. This cable uses a crossover wiring assignment, so it is intended for direct connections between compatible devices (for example, between two computers or certain network devices that require a crossover). Ensure ports are powered down if required by device instructions before connecting or disconnecting. Verify link status LEDs on devices to confirm a successful connection.

Recommendations

For standard structured cabling where straight-through wiring is required, use a standard Cat5e patch cable; use this crossover cable only when a crossover connection is needed. Avoid sharp bends and do not subject the cable to excessive pulling to maintain connector and shielding integrity.
