Copper Foil EMI Shielding Split Braided Wire Sleeve

MJ FLEX MBS-CFW-S is a self-closing split shielding sleeve braided with conductive copper foil filaments. Its side-entry construction wraps around installed cables without removing connectors, while the lightweight braid follows bends and changing bundle profiles. It is designed for serviceable signal harnesses that need conductive coverage with less weight and stiffness than a conventional solid-wire metal braid.

  • Why Choose MBS-CFW-S Self Closing Shielding Sleeving?

    • Add shielding to completed harnesses

    The split construction installs around terminated cables, branches and connectors.

    • Reduce added weight and bulk

    Copper foil filaments provide a lightweight conductive braid for compact assemblies.

    • Keep wiring accessible 

    The self-closing overlap can be opened locally for inspection, cable additions and repair.

    • Preserve flexible routing 

    The braid follows curved paths and irregular bundles without rigid metallic conduit.

     

    Key Features

    1. Conductive copper foil filaments 

    Creates a lightweight shielding layer around cable bundles.

    2. Self-closing split construction 

    Supports side-entry installation and automatic wrap-around coverage.

    3. Retrofit-friendly design

    Fits existing harnesses without connector removal.

    4. Flexible braided structure

    Conforms to bends and moderate bundle-diameter variation.

    5. EMI and RFI shielding support

    Helps control radiated interference when correctly grounded and terminated.

    6. Accessible branch points

    Allows local opening for cable exits and maintenance.

    7. Custom braid configurations

    Size, coverage, overlap, length and packaging can be reviewed for OEM projects.

    Typical Applications
    Electronic instruments 
    Protects low-level signal wiring where added shield weight and stiffness should be minimized.
    Robotics and automation
    Wraps feedback and control cables near motors and drives while preserving service access.
    Communication equipment
    Adds conductive coverage around compact data and signal bundles in crowded enclosures.
    Vehicle electronic systems 
    Retrofits shielding around auxiliary and communication harnesses near electrical noise sources.
    Medical and laboratory equipment 
    Helps separate sensitive signal cables from nearby interference; final equipment EMC validation remains required.

    How to Select

    Provide the minimum and maximum bundle diameter, required overlap, target frequency range and intended grounding method. Also identify bend radius, flex cycles, branches, connectors and environmental exposure. Copper foil braid is mainly selected for lightweight flexibility; applications requiring a robust bonding path, lower resistance or higher current capacity should be evaluated against MBS-TC-S.

     

    Customization Available

    Nominal size and overlap - Matched to the actual bundle range and coverage target.

    Braid density and filament construction - Adjusted for flexibility, weight and shielding priorities.

    Cut lengths and branch preparation - Project-specific pieces available after drawing review.

    Identification and packaging - Labels, reels, kits and OEM packaging available by agreement.

     

    Testing and Compliance

    RoHS and REACH documents may be available for the confirmed construction. Shielding effectiveness, resistance, temperature and flex life must be stated only against an agreed test method and sample configuration. Final EMC compliance depends on the complete cable assembly, including overlap, seams, grounding and termination.

     

    Quality Assurance

    Filament identity check - Copper foil filament construction and incoming condition are verified.

    Braid and overlap inspection - Coverage consistency, broken filaments and self-closing behavior are monitored.

    Dimensional verification - Nominal size, overlap and finished length are checked.

    Functional release - Continuity or resistance checks can be agreed with final label and packaging review.

    Frequently Asked Questions

    01. Can it be installed after connectors are fitted?
    Yes. The split design wraps around the existing harness from the side.
    02. Does the overlap affect shielding performance?
    Yes. Insufficient or inconsistent overlap can create shielding gaps, especially at bends and branches.
    03.Can it be used as a grounding strap?
    It is primarily a lightweight shielding wrap; use a tinned copper construction when a robust bonding or current path is required.
