EFB Elektronik K2793.0,50 Cabo de rede patch crossover RJ45 Cat.5e SF/UTP, Hirose TM11, Draka UC300, 0,5 m, vermelho

Connect two computers directly without a switch or hub using this EFB Elektronik crossover cable. In a small office or lab, a technician can link a laptop to a desktop for fast file transfers, or you can cascade older network hardware that lacks auto-MDIX. The cable’s crossover wiring swaps the transmit and receive pairs, so data flows correctly between identical devices. At 2 metres long, it reaches between nearby workstations or from a patch panel to a test rig without excess slack. The grey PVC jacket blends into cable trays and keeps the four twisted pairs protected in everyday use.

Why choose it

This crossover cable is built for direct device-to-device links. The gold-plated contacts resist corrosion and maintain a clean signal over repeated plugging. Stranded copper conductors give the cable enough flexibility to route around desks or through tight spaces without breaking. Because it is Cat5e, it supports Fast Ethernet speeds reliably, and the UTP construction keeps the cable light and easy to handle. The grey colour is neutral and professional, matching most office environments.

Ideal use cases

• Direct PC-to-PC file transfer without a network switch
• Connecting two hubs or two switches in a legacy network
• Linking a network analyser or test equipment to a laptop
• Temporary ad-hoc networks for diagnostics or configuration

Good to know

Most modern Gigabit Ethernet ports support Auto-MDIX, which automatically detects and corrects cable type, making crossover cables less common in new installations. However, this cable remains essential for older equipment, industrial controllers, or any device that does not implement Auto-MDIX. The cable is RoHS compliant and uses standard RJ45 connectors, so it works with any Ethernet port. Store it loosely coiled to avoid kinks and preserve the twisted-pair geometry.
