RJ11 6P4C Flat Telephone Cable Assembly

A flat RJ11 6P4C telephone cable assembly for voice and low-speed communication equipment. The flat profile runs under carpet edges and behind wall trim where a round cable would sit proud, which is why it stays the default for telephone cords.

  • Flat profile routes cleanly along skirting and under desk edges
  • 6P4C plugs match standard telephone and communication device jacks
  • 3m standard length covers desk and wall-plate runs
  • Moulded strain relief survives repeated plug and unplug cycles

Samples ship within 3 days of confirmation. Bulk lead time is typically 7 to 12 days.

Problems It Solves

  • Round cords sit proud of trim and get pinched by furniture
  • Generic cords fail at the plug after a few hundred insertions
  • Wrong conductor count breaks two-line telephone systems

Who It Is For

  • Telecom equipment suppliers
  • Hospitality and office fit-out contractors
  • Device makers bundling a line cord

Application Scenarios

  • Telephone handsets and base units
  • Communication equipment with RJ11 line ports
  • Office and hospitality installs

  • Circuit Configuration Verification. Confirms that a complete, uninterrupted current flow path exists within each circuit
  • Terminal Retention Strength Test. Measures the mechanical reliability of the connection between the terminal and the wire
  • Ingress Protection Rating Test. Evaluates the dust and water resistance sealing performance of harness connectors

The company is certified to IATF 16949 and UL standards. Samples are confirmed prior to trial or mass production, and the approved sample is the reference for every repeat order.

Customization Options

  • Connector family and terminal type to your part numbers
  • Conductor gauge selected from the current per circuit
  • Finished length and breakout positions to your drawing
  • Jacket colour, marking and labelling to your scheme
  • Packing to your instruction, PE bag and carton as standard

Compared With The Alternatives

Round RJ11 cords

A flat cord lies under trim and carpet edges without a bulge

Coiled handset cords

A straight flat cord suits fixed wall to device runs instead of handsets

Use Guide

  • Press the latch fully until it clicks, then release so the retention tab seats
  • Avoid sharp folds in the flat cable, which crack conductors over time
  • Do not run alongside mains cabling for long parallel distances
