Networking Cable EFB Elektronik K8449.1 1m Cat5e F/UTP

The EFB Elektronik K8449.1 is a 1 m Cat5e networking cable with F/UTP construction and shielded Hirose TM11 RJ45 plugs. Designed for Gigabit Ethernet crossover connections, it provides foil shielding around four twisted pairs assembled from AWG26/7 conductors and meets relevant flame retardant and low-smoke safety standards. The cable is grey and includes a mounted red strain relief (without latch protection).

Advantages

F/UTP foil shielding reduces electromagnetic interference and supports stable data transmission over 100 MHz Cat5e specification. Shielded Hirose TM11 RJ45 plugs (IEC 60603-7-3) provide a secure, grounded connection. The crossover pin assignment allows direct device-to-device links without an intermediary switch. The cable conforms to IEC 60332-1 (flame retardant), IEC 60754-2 (halogen free) and IEC 61034 (low smoke), which supports safer use in enclosed spaces.

Suitable for

• Direct device-to-device Gigabit Ethernet connections (crossover)
• Office and home network patching where screened cable is required
• Environments demanding flame-retardant and low-smoke cabling

How to use

Connect each RJ45 plug to the corresponding Ethernet port on the devices you want to link. Because this is a crossover cable with the specified 1-3, 2-6, 3-1 ... wiring, it is intended for direct connections between two network endpoints (for example PC-to-PC or switch-to-switch where crossover is required). Ensure connectors are fully seated and that shielding is grounded via the equipment chassis if available. Avoid sharp bends and excessive pulling; observe the cable's minimum bend radius to maintain performance.

Recommendations

Use this cable for short runs up to 1 m in installations that benefit from screened cabling and where crossover wiring is required. For permanent in-wall installations or distances beyond Cat5e recommendations, consider suitable permanent cabling products and installation practices.
