InLine 18748 Telephone Cable 15 m Grey RJ-12 to RJ-12 6-Core Round Cable

The InLine 18748 telephone cable is a 15-metre modular round cable designed to connect telephones, modems, and communication systems over extended distances. Featuring a grey jacket, pure copper conductors with AWG26 sizing, and two RJ-12 6P6C male connectors on both ends, this 6-core internal wiring design ensures reliable signal transmission for both voice and data devices. The cable provides a stable connection for telecommunications, control systems, and sensor technology.

Advantages

The pure copper conductors reduce line resistance and guarantee dependable signal quality even when spanning longer distances. The moulded RJ-12 connectors significantly enhance mechanical stability, protecting the interface during frequent plugging and unplugging in continuous use environments. Its round cable geometry allows for much easier routing compared to standard flat cables, facilitating neat structured installations. Furthermore, the fully pinned 6-core design supports applications that require all six signal paths.

Suitable for

• Connecting telephones and modems over extended distances
• Integrating communication systems and telephone exchanges
• Signal transmission in control and regulation systems
• Applications in sensor technology and data wiring

When it may not be suitable

This cable is not designed for high-speed Ethernet networking or structured LAN installations that require RJ-45 connectors. Additionally, the 15-metre length may be excessive for devices located close to each other, potentially leading to unnecessary cable clutter.

How to use

Ensure that the devices you wish to connect feature compatible RJ-12 ports before installation. Take one end of the 15-metre round cable and firmly insert the RJ-12 male connector into the port of the first device until it clicks into place. Route the cable safely along walls or through cable channels to avoid tripping hazards or sharp bends. Finally, insert the second RJ-12 connector into the corresponding port of the receiving telephone, modem, or communication system.

What to consider before purchase

• Verify that your hardware utilizes RJ-12 6P6C interfaces rather than standard RJ-11 or RJ-45 ports
• Measure the distance between devices to confirm that the 15-metre length suits your setup
• Check if a round cable profile fits your routing and cable management requirements

Usage recommendations: Avoid tightly bending the cable or placing heavy objects on it to maintain optimal signal integrity. Store excess cable in a gentle loop if the full 15-metre length is not required.
