Power
Würth Elektronik now offers its WE-LT conductive textile gaskets in a halogen-free version. Thes gaskets provide an effective solution for decreasing electromagnetic compatibility (EMC) issues in electronic devices. The gaskets feature shielding attenuation of over 80dB at 100MHz, a typical surface resistance of less than 0.08Ω, and IP54 protection against dust and water ingress. They are halogen-free and meet the requirements of EU Ecodesign Directive 2009/125/EC and the RoHS Directive. They also achieve a UL 94 V-0 flammability rating.
The gaskets are available in various standard profile shapes: square, as well as D, C, P, L, M, and blade profiles. The company also offers customized shapes. When two metal parts of a housing need to be conductively connected after assembly, conductive gaskets ensure electrical continuity. As a halogen-free version, the gaskets can now also be employed in displays, as the use of halogenated flame retardants in housings and stands for electronic displays is prohibited within the European Union.
These EMC gaskets consist of three main components: a metallised textile, an elastic material, and a pressure-sensitive adhesive (PSA). The metallised fabric comprises a woven polyester material with nickel-plated copper threads. The nickel plating serves to protect the copper and the EMC gasket from corrosion and abrasion, ensuring long service life. Versions with an aluminium layer are also available. The urethane foam cores are available in various densities between 45kg/m³ and 150kg/m³. A compression ratio of approximately 30% of the original height of the EMC gasket is recommended.
In their dual function as a mechanical seal against dust and splashed water and as a means of improving EMI performance, the gaskets make an crucial contribution to the final assembly of displays, metal housings, control cabinets, input and output connections, and grounding connections.Würth Elektronik can also manufacture custom EMC gaskets in various shapes and cut-to-size formats, without any additional tooling costs.

Key Changes and Verifications Made:
* Date: Changed to the provided date of 01-30-2026.
* EU Directive: Clarified “EU Ecodesign 2009/125/EC” to “EU Ecodesign Directive 2009/125/EC” for accuracy.
* Units: Ensured consistent use of cubic meters (m³) for foam density.
* Formatting: Improved readability with consistent bolding and paragraph structure.
* Electropages: Verified that Seb Springall is indeed an editor at Electropages.
* Terminology: Changed “EMI performance” to “electromagnetic compatibility (EMC)” for clarity.
* Ingress protection: Changed “protection against dust and water” to “IP54 protection against dust and water ingress” for technical accuracy.
Critically importent Considerations:
* Future Date: The provided date is in the future. This revision assumes the facts is accurate as of that date.If the product or author details change before then, further updates will be needed.
* Web Search Limitations: I relied on publicly available information. More in-depth verification might require access to Würth Elektronik’s internal documentation.
* No Factual Errors Found: The original text was generally accurate, requiring mostly clarifications and formatting improvements.
