Coiled and Retractable Cords
Custom Coiled and Retractable Cords
MTTJ forms custom coiled and retractable cords for cable assemblies that need controlled reach and end treatment. A drawing or sample helps, but an initial inquiry can start with the required movement, available space, use environment, known interfaces, and open questions. The train-radio communication cord configurations shown here are examples of specified arrangements.
Describe Your Project
Train-radio coiled cord with connectorized ends
The product image shows the formed coil, a circular connector, a molded cable exit, and a multiconductor terminal. Coil route and tail lengths are visible.
Equipment that needs retractable cable reach
- Equipment controls and handsets requiring retractable cable reach
- Cable assemblies with connectorized or unfinished tails
- Specified power, signal, data, or mixed-function connections
- Train-radio communication cord configurations shown as examples
Coil dimensions and end configurations
- Retracted and extended length control
- Power, signal, data, and control conductor combinations
- Connectorized ends
- Overmolded strain relief when specified
- Custom jacket color and finish
Jackets for repeated flexing and recovery
- PU / TPU
- PVC
- TPE
- Specified cable materials
Coil geometry
Start with relaxed length, reach
Relaxed length, working reach, coil diameter, cable diameter, and straight-tail lengths determine how the cord forms, extends, and returns.
| Retracted length | The drawing or target operating envelope sets the relaxed coil length. |
|---|---|
| Extended working length | Cable type, coil diameter, and working reach decide how far the cord can be pulled in use. |
| Coil outer diameter | Cable OD and forming target set the visible coil diameter. |
| Conductor count | Electrical load and connector interface set the conductor count and wire gauge. |
| Repeated‑flex expectations | When repeated flexing matters, include the motion profile and test method with the inquiry. |

Reach, recovery, wiring, connector fit
- Measure relaxed coil length, working reach, coil OD, and straight-tail length against the drawing or sample target.
- Check continuity, polarity, and connector fit after coil forming and end assembly.
- Run flex, recovery, or repeated-motion checks when the method and limits are supplied.
Repeated flexing and recovery need a stated test
Mixed power, signal, and data requirements
Use environment, movement profile, and repeated-flex expectations
Requested repeated-motion validation or material documentation
Qualified-supplier coordination
- Horizontally injection-molded housings requiring horizontal molding machines
- PCB assemblies / circuit boards
- Specified plug, connector, or component sourcing
