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

The InLine 18749 telephone cable is a reliable 20-meter modular round cable featuring RJ-12 connectors on both ends. Designed for professional office environments and telecommunication installations, this 6-wire 6P6C cable ensures stable and secure signal transmission over longer distances. Built with pure copper conductors and moulded connectors, it provides dependable performance for various communication and control systems.

Advantages

The cable utilizes pure copper conductors with an AWG26 cross-section, significantly reducing line resistance to maintain optimal signal quality over extended lengths. Its fully pinned 6P6C configuration connects all six contacts, making it versatile for applications requiring complete signal paths. The round cable shape offers improved flexibility and easier routing compared to standard flat cables, ensuring neat management in cable ducts and along routing paths. Additionally, the robust moulded RJ12 connectors enhance mechanical durability, protecting the interface during frequent plugging cycles in continuous professional use.

Suitable for

• Connecting telephones and fax machines in office environments
• Telecommunication installations and PBX system wiring
• Control, regulation, and sensor technology systems
• Extended distance signal connections requiring a 6-wire configuration

When it may not be suitable

This cable is not designed for Ethernet networking or high-speed internet connections that require RJ-45 plugs and network protocols. It is also unsuitable for very short connections where a 20-meter length would create excessive cable slack and clutter.

Key specifications

• Cable length: 20 m
• Connector type: RJ-12 male to RJ-12 male
• Wiring configuration: 6P6C, 6-wire full pinout
• Conductor material: Pure copper (AWG26)
• Cable shape: Round
• Colour: Grey

How to use

Ensure that the connected devices are compatible with RJ-12 6P6C connections before installation. Insert the RJ-12 plug into the telephone or telecommunication device port until it clicks securely into place. Route the 20-meter round cable carefully along walls, through cable ducts, or behind furniture, avoiding sharp bends or excessive pulling force to maintain cable integrity. To disconnect, press the plastic locking tab on the plug and pull straight out without tugging on the cable itself.

What to consider before purchase

• Verify that your devices require an RJ-12 connector and a 6-wire 6P6C configuration rather than standard RJ-11 or RJ-45 plugs.
• Measure the distance between your devices to ensure that the 20-meter length is appropriate without leaving an unmanageable amount of excess cable.
• Check available space in cable channels or conduits to ensure the round cable profile fits your installation layout.

Usage recommendations: Plan the routing path in advance to avoid stepping on the cable or exposing it to heavy office traffic. Secure loose sections along baseboards or inside conduits to prevent accidental tripping hazards and mechanical wear over time.
