Shielded Wire Harness

A shielded wire harness adds a conductive shielding layer – typically aluminum foil, braid, or a combination of both – around signal conductors to block electromagnetic interference from nearby power lines, motors and radio sources. The shield preserves the integrity of sensitive signals, which is why shielded harnesses are specified in medical imaging equipment, communication devices and precision instruments.

Description

Shielding is only useful if it is designed for the actual interference path and assembled so the shield stays continuous. Our team reviews the application and the critical signal paths during the drawing phase, then applies foil, braid or combined shielding where it is needed, including the transition into the connector. The assembled harness is covered by reliability test reports, and a sample is confirmed before production so the shielding performance is verified on the actual configuration.

Applications

Medical imaging

MRI and similar instruments need low-noise, high-shielding internal cable runs to keep signal quality stable.

Communication equipment

Shielded harnesses prevent interference from switching power supplies and radio stages.

Precision instruments

Measurement accuracy depends on protecting low-level signals from EMI.

Customization

We customize shielding structure (foil, braid, or combined; full or selective), conductor schedule, connector type and pin layout, length, jacket material and grounding arrangement. Production follows customer drawings or samples with a confirmed sample before mass production.

Packaging & Transportation

Each batch is inspected before shipment and ships with outgoing inspection and reliability test reports. In-stock items ship within about 48 hours; custom orders typically 15–21 days (excluding shipping). Payment is deposit plus balance before shipment.

FAQ

Q1. Can you add shielding to a wire harness?

A: Yes. Foil, braid or combined shielding can be applied to selected wires or the full bundle according to the application, and the configuration is confirmed during design review.

Q2. How do you verify interference resistance?

A: The harness is produced to the approved sample and covered by reliability test reports; our factory has reliability testing equipment for validation.

Q3. Can we get a sample of a shielded harness?

A: Yes. When existing tooling and materials match, samples of around 5 pcs are free of charge; otherwise sample cost and tooling are discussed per project.
