Καλώδιο δικτύου EFB Elektronik K5456.25 25m Cat5e SF/UTP RJ-45

The EFB Elektronik K5456.25 is a 25 m Cat5e SF/UTP networking cable designed for wired Ethernet connections. It combines twisted-pair conductors with an SF/UTP shielding arrangement to reduce electromagnetic interference and preserve signal integrity. Fitted with RJ-45 connectors with gold-plated contacts, the cable supports data transfer rates up to 2500 Mbit/s and is suitable for structured cabling in offices, server rooms, and home networks.

Advantages

The SF/UTP shielding construction minimizes crosstalk and external interference while maintaining flexibility for routing and installation. Gold-plated RJ-45 contacts provide reliable contact resistance and corrosion resistance for long-term connectivity. With a 25 m length, the cable accommodates mid-range distances without the need for additional patching, and the black jacket offers a neutral appearance for concealed or visible installations.

Suitable for

• Ethernet connections between switches, routers and networked devices
• Patch cabling in small offices and home networks
• Connections in server cabinets and wiring closets
• Temporary or permanent installations where EMI reduction is needed

Key specifications

• Standard: Cat5e
• Shielding: SF/UTP (foil screen with braided overall)
• Length: 25 m
• Connectors: RJ-45 to RJ-45
• Contact plating: gold-plated contacts
• Color: black
• Maximum data rate: up to 2500 Mbit/s

How to use

Route the cable between network devices, avoiding sharp bends and tight kinks. Insert the RJ-45 connectors firmly into the corresponding Ethernet ports until the latch engages. For installations near potential sources of interference, ensure the cable's shield is properly terminated at patch panels or shielded connectors to maintain shielding effectiveness. When cutting to length is necessary, re-terminate using compatible shielded RJ-45 plugs or a keystone module designed for SF/UTP cabling.

Recommendations

Avoid running the cable parallel to high-voltage power lines and keep minimum separation from fluorescent lighting fixtures and large motors. Secure the cable with appropriate cable ties or Velcro straps without compressing the jacket, and maintain bend radius recommendations for Cat5e cabling to preserve performance.
