Networking Cable EFB Elektronik K5458.20 RJ-45 Cat5e 20m Red

Networking Cable EFB Elektronik K5458.20 RJ-45 Cat5e 20m Red is a 20-metre Cat5e patch cable designed for 10/100/1000Base-T(X) networks. The cable uses SF/UTP (S-FTP) construction with foil and braid shielding and is fitted with two shielded RJ45 plugs (IEC 60603-7-3). It is colour-coded red and meets flame retardant standard IEC 60332-1 with TIA/EIA 568B wiring.

Advantages

The SF/UTP construction with foil and braid shielding reduces electromagnetic interference and crosstalk, supporting gigabit Ethernet performance over 20 metres. Shielded RJ45 plugs ensure reliable connector contact and compliance with IEC 60603-7-3. The moulded strain relief boot with latch protection protects the connector and latch during installation and use.

Suitable for

• Wiring between switches, routers and patch panels in office or server-room environments
• Gigabit Ethernet (10/100/1000Base-T(X)) connections
• Applications requiring shielded cabling to reduce EMI

Key specifications

• Length: 20 m
• Cable category: Cat5e, 100 MHz
• Connectors: 2 × RJ-45 shielded (IEC 60603-7-3)
• Cabling: SF/UTP (S-FTP), 4 × 2 × AWG26/7, PVC, Ø 5.7 mm
• Wiring: TIA/EIA 568B
• Flame retardant: IEC 60332-1
• Colour: Red

How to use

Connect one RJ-45 plug to your network device (switch, router or network interface) and the other plug to the corresponding port. Ensure connectors are fully inserted until the latch clicks and route the cable to avoid sharp bends and excessive tension. For installations in shielded environments, verify that equipment chassis or patch panels provide proper grounding for the shielded cable.

Recommendations

Use this Cat5e SF/UTP cable for short- to medium-length gigabit connections where reduced electromagnetic interference is required. Avoid running the cable parallel to high-voltage power lines and maintain minimum bend radius to preserve performance. Ensure shielding is properly terminated at both ends for optimal EMI protection.
