Networking Cable EFB Elektronik K5450.1 1m Cat5e SF/UTP

The EFB Elektronik K5450.1 is a 1 m Cat5e SF/UTP crossover patch cable designed for Gigabit Ethernet applications. It uses shielded RJ45 plugs (IEC 60603-7-3) on both ends and a foil-and-braid screened SF/UTP core with four twisted pairs (AWG26/7) inside a PVC jacket. The molded red strain relief with latch protection and flame-retardant construction (IEC 60332-1) provide durability and safety for structured networks.

Advantages

This Cat5e crossover cable supports 1 Gigabit Ethernet at up to 100 MHz and reduces electromagnetic interference thanks to foil and braid shielding. Shielded RJ45 plugs and a robust PVC outer jacket increase mechanical reliability, while the molded strain relief protects the connector latch and cable entry. The product conforms to relevant IEC standards for connector dimensions and flame retardance.

Suitable for

• Direct device-to-device connections without a switch (crossover use)
• Short runs in office and server closet environments (1 m length)
• Environments requiring improved EMI protection thanks to SF/UTP shielding
• Installations where a protected latch and strain relief are needed

How to use

Connect each RJ45 plug to the Ethernet ports of the devices you want to link directly (for example, two computers or a computer and a switch/router configured for crossover). Ensure that connectors are fully inserted until the latch clicks and that the molded strain relief seats against the device panel to reduce stress on the cable. Because this is a crossover cable, verify your equipment’s port requirements before use.

Recommendations

Use the cable for short, indoor connections where Cat5e performance and additional shielding are sufficient. Avoid tight bending near connectors and keep the cable away from strong sources of interference despite its shielding. For longer runs or higher performance needs, consider Cat6/Cat6a alternatives.
