InLine 18749 Telephone Cable RJ-12 to RJ-12 6P6C 6-wire Round 20 m Grey

The InLine 18749 Telephone Cable RJ-12 to RJ-12 6P6C 6-wire Round 20 m Grey is a reliable telecommunication cable designed to link analog or digital devices such as telephones and modems to wall outlets. With a generous length of 20 metres, this round grey cable enables flexible placement of equipment across rooms or within technical setups. Built with pure copper conductors and a fully pinned 6P6C configuration, it ensures dependable signal transmission for both standard communication tasks and specialized technical applications.

Advantages

This telephone cable utilizes pure copper conductors in an AWG26 gauge, which significantly reduces line resistance and maintains stable signal quality over extended distances. The moulded RJ-12 connectors provide enhanced mechanical stability, protecting the connection points against wear during frequent plugging and unplugging. Thanks to its round cross-section, the cable routes more easily than flat alternatives, facilitating neat and orderly cable management in complex environments. All six contacts are fully wired, allowing the cable to support applications that require complete signal pinning across all paths.

Suitable for

• Connecting analog or digital telephones to wall sockets
• Linking modems and fax machines in home and office environments
• Signal transmission in control and regulation systems
• Use in specialized sensor technology and technical communication setups

When it may not be suitable

This cable is not designed for Ethernet network connections, local area network computer networking, or high-speed internet applications that require RJ-45 connectors. It is also unsuitable for outdoor installations where it would be directly exposed to harsh weather conditions and moisture without protective conduits.

How to use

To use the cable, insert one of the RJ-12 connectors into the output port of your telecommunication device, modem, or control unit until it clicks securely into place. Route the 20-metre round cable carefully along baseboards, through cable ducts, or behind furniture to prevent sharp bends or pinching that could damage the internal pure copper wires. Finally, plug the remaining RJ-12 connector into the corresponding wall outlet or receiver port. Ensure the connectors are kept dry and free from dust to maintain optimal signal transmission over time.

What to consider before purchase

• Verify that your devices and wall outlets feature compatible RJ-12 ports and require a 6-wire 6P6C pinout.
• Measure the required distance between your devices to ensure the 20-metre length is sufficient without creating excessive cable slack.
• Check whether a round cable profile matches your planned routing path and cable management requirements.

For optimal performance, route the cable away from heavy electrical power lines to minimize potential electromagnetic interference, and avoid placing heavy objects directly on top of the cable run.
