Networking Cable EFB Elektronik K5450.3 3m Cat5e SF/UTP Grey

The EFB Elektronik K5450.3 is a 3 m Cat5e SF/UTP crossover patch cable designed for Gigabit Ethernet connections. It features shielded RJ45 plugs on both ends and a molded strain relief in red with latch protection, meeting flame-retardant standard IEC 60332-1. The cable construction uses SF/UTP 4 x 2 x AWG26/7 conductors with foil and braid shielding and an outer PVC jacket, diameter 5.7 mm.

Advantages

This Cat5e crossover cable supports data rates suitable for Gigabit Ethernet over a 100 MHz bandwidth and provides improved interference protection thanks to foil and braid shielding (SF/UTP). Shielded IEC 60603-7-3 RJ45 plugs and a molded strain relief with latch protection increase connector reliability and mechanical durability. The flame-retardant jacket adds safety for indoor installations.

Suitable for

• Connecting two network devices directly (PC-to-PC or switch-to-switch) requiring a crossover wiring assignment
• Temporary or permanent Ethernet links in small office and home networks
• Situations where additional electromagnetic shielding is needed

Key specifications

How to use

Plug each shielded RJ45 connector into the Ethernet ports of the devices to be connected, ensuring the latch engages. Use this crossover cable when a direct device-to-device connection requiring crossed pairs is necessary. Route the cable to avoid sharp bends and protect the molded strain relief from excessive tension.

Recommendations

For optimal performance, use the cable for short to medium runs up to typical Ethernet distances, avoid running parallel to strong electrical sources to reduce interference, and ensure both connected devices support the intended crossover connection or use an intermediate switch if required.
