Professional Shielded Wire Harness Manufacturing for EMI/RFI Protection
As a trusted shielded wire harness manufacturer, OurPCB delivers EMI-protected cable assemblies that ensure signal integrity in electrically noisy environments. Our wire harness solutions incorporate braided shields, foil shields, and combination shielding configurations to meet your specific electromagnetic compatibility (EMC) requirements.
Our EMI shielded cable products serve critical applications across multiple industries. For medical devices, we provide shielded harnesses for patient monitoring equipment, diagnostic imaging systems, and surgical instruments where signal accuracy is paramount. In industrial automation, our shielded cables protect PLC communications and sensor signals from motor drive interference.
We offer complete shielding solutions from individual pair shielding to overall harness shields. Our braided copper shields achieve 85-98% coverage for general EMI protection, while foil shields provide 100% coverage for high-frequency noise rejection. For critical applications like high-voltage EV systems and medical devices, we offer combination foil+braid shielding for maximum protection across all frequency ranges.
Proper shield termination is essential for effective EMI protection. Our testing capabilities verify shield effectiveness, and our engineering team provides guidance on 360° backshell terminations, drain wire configurations, and grounding strategies. Whether you need custom shielded harness designs or production-ready solutions, we deliver EMC-compliant assemblies.
Our ISO 9001 certified facilities produce shielded wire harnesses for automotive, communications, test equipment, and audio/video applications. With 48-hour prototyping and no MOQ requirements, you can validate your shielded cable design before volume production. Contact us to discuss your EMI protection requirements.
Shielded Harness FAQ
The best shielding type depends on your application: Braided shields (85-98% coverage) are ideal for general EMI protection and flexible applications. Foil shields (100% coverage) are best for high-frequency interference. Combination foil+braid provides maximum protection for critical applications. We can recommend the optimal shielding based on your EMC requirements.
Shield termination options include: pigtail connection to ground, 360° backshell termination, crimp ferrule, solder to connector shell, and drain wire connection. Proper termination is critical for shielding effectiveness - we can recommend the best approach for your connector and application.
Yes, we can provide individually shielded pairs or groups within a multi-conductor harness. This is common for mixed signal/power cables where sensitive signals need protection from adjacent power conductors. We can also provide overall shields in addition to individual shields.
Shield coverage refers to the percentage of the cable surface covered by the shield. Higher coverage provides better EMI protection. Braided shields typically achieve 85-95% coverage (higher with denser braids), while foil shields achieve 100% coverage. The required coverage depends on your EMC requirements and interference frequency.
