Shielded TPU Coiled Cable

TPU coiled cable manufacturer | Compare TPU coiled cable applications

Quick answer: A shielded TPU coiled cable combines an extendable cable form with a shielding construction selected for signal integrity or noise-control requirements. Nexharn Connectivity reviews the signal type, power conductors, shielding method, grounding approach, coil dimensions, connector termination, movement and test criteria before sampling. Shielding performance depends on the complete design and should never be assumed from the presence of foil or braid alone.

Shielded TPU Coiled Cable Product Overview

Shielded coiled cables require coordination between conductor layout, shield coverage, connector design and mechanical movement. Coiling can change geometry and stress the shield during repeated extension. Buyers should identify the signal, frequency range, surrounding interference sources, grounding strategy and acceptable test method so the supplier can propose a practical construction.

Typical Applications

• Sensors, encoders and measurement instruments
• Barcode scanners and industrial handheld devices
• Machine controls and robotic peripheral equipment
• Low-voltage power combined with signal circuits
• Equipment operating near motors, drives or other noise sources

Customization Options

• Foil, braid, drain wire or combined shielding options
• Twisted pairs and conductor arrangement
• Shield termination at one or both ends
• Connector shell and grounding configuration
• Coil dimensions, TPU hardness and straight tails
• Continuity, shielding and application-specific test requirements

Technical Specifications

Cable Structure and Construction Options

Options may include aluminum foil with drain wire, copper braid, or a combined foil-and-braid system. Twisted pairs may be used where appropriate. The shield must be terminated deliberately at the connector or cable end, and a TPU jacket protects the moving assembly. Each shielding method has tradeoffs in flexibility, diameter, cost and termination complexity.

Tradeoffs should be reviewed rather than hidden. Increasing conductor size or adding shielding may increase cable diameter and weight. A tighter coil can increase stress, while a longer extension can affect voltage drop, return force and service life. Nexharn confirms the proposed construction and sample acceptance plan before mass production.

Why TPU for This Application

TPU supports a flexible and abrasion-resistant outer surface for moving equipment, while the internal shield addresses electrical noise requirements. The mechanical design must avoid excessive stress on foil, braid and drain wires. A larger coil or controlled working extension may be needed to protect the structure during repeated use.

Testing and Quality Control

Test requirements and acceptance criteria are confirmed before sampling. Production inspection follows the approved drawing, sample and order specification.

• Continuity and pinout inspection
• Shield continuity and termination verification
• Insulation and electrical testing as specified
• Dimensional, stretch and rebound checks
• Application-specific noise or signal testing when criteria are supplied
• Connector, strain-relief and visual inspection

Information Required for Quotation

For an efficient engineering review, send the target application, wiring or pinout, electrical requirement, natural coil length, normal working extension, coil outside diameter, straight tail lengths, connector details, working environment, estimated quantity, packaging and destination market. A drawing is helpful but not mandatory; equipment photos, an existing sample or a dimensioned sketch can be used to begin discussion.

Buyer FAQ

Which shielding option is best?

There is no universal choice. Foil, braid and combined shielding differ in coverage, flexibility, diameter, termination and cost. Selection depends on signal and environment.

Can shielding guarantee a specific EMI result?

No. Results depend on cable construction, shield termination, connector, grounding, equipment and test setup. Acceptance criteria should be defined before sampling.

Can power and signal conductors share the same coiled cable?

Sometimes, but conductor separation, current, signal sensitivity, shielding and connector pinout must be reviewed. Separate cables may be preferable in demanding applications.

Should the shield be connected at both ends?

That depends on the system grounding strategy and noise environment. Nexharn follows the buyer’s approved wiring and termination requirements.

What should be sent for quotation?

Send signal details, wiring diagram, shielding request, grounding plan, coil dimensions, connector, movement, environment, quantity and test criteria.

MOQ and Lead Time

MOQ is quoted after the conductor construction, TPU grade, connector, tooling, testing and packaging are reviewed. Sample and production lead times are estimated after the drawing revision, material availability, quantity and approval route are confirmed. Request written project terms; no fixed MOQ or delivery promise applies to every custom cable.

Testing and Custom-Option Resources

For project-specific test methods, equipment and acceptance records, review TPU cable testing and quality equipment. Use the RFQ, sample approval and packaging worksheets to describe custom conductor, connector, coil geometry, shielding, labels and pack options before quotation.
