Specifications
Key specifications to define before quotation
Final requirements should come from customer drawings, specifications, test methods, acceptance criteria, and project documentation.
| Retracted length | Specified by customer drawing or target operating envelope |
|---|---|
| Extended working length | Reviewed with cable type, coil diameter, and application expectations |
| Coil outer diameter | Defined by design target, cable outside diameter, and forming requirements |
| Conductor count | Confirmed with electrical requirements and connector configuration |
| Flex-cycle expectations | Reviewed during RFQ with cable type, coil geometry, application profile, and supplied test criteria |

FAQ
Common RFQ questions
What is the difference between retracted length and extended length?
Retracted length is the relaxed coil length, while extended length describes the intended working reach when the cord is pulled in use.
Can coiled cords carry power and signal in one cable?
Mixed power, signal, data, and control requirements can be reviewed during RFQ with the cable construction and connector configuration.
What should be supplied before quoting a coiled cord?
Please provide relaxed length, working length, coil diameter, cable type, conductor count, connector requirements, quantity, and application environment.
