SCHROFF EMC textile gasket for 3U (3HE) panels, pack of 10, model 21101853

EMC textile gasket SCHROFF model 21101853 is designed to provide conductive sealing for 3U (3HE) panels used in racks and enclosures. Supplied as a pack of 10, each gasket creates a resilient conductive interface between panel edges and the chassis, helping to reduce electromagnetic interference (EMI) leakage and maintain electromagnetic compatibility in electronic equipment. The gasket material and profile are optimized for installation on standard 3U panels to ensure consistent contact pressure and reliable shielding performance.

Advantages

The SCHROFF EMC textile gasket delivers a combination of good electrical conductivity and mechanical flexibility that simplifies retrofitting and new installations. Its textile construction conforms to irregular surfaces and compensates for minor panel-to-chassis gaps, while conductive fibers maintain an electrical path for shielding. Packaging as a 10-piece set supports multiple panels or spare-stock requirements, reducing downtime during maintenance or upgrades. The gasket is lightweight, non-invasive to panel cosmetics, and designed for repeated installation cycles without significant loss of contact integrity.

Suitable for

• Sealing 3U (3HE) front or rear panels in server and telecom racks
• Improving EMI shielding in industrial control cabinets and instrumentation enclosures
• Retrofit projects where existing panels require additional conductive sealing
• Applications requiring a non-metallic, conformable gasket that still provides conductive contact

Key specifications

• Form factor: designed for 3U (3HE) panels
• Material: conductive textile with resilient backing for consistent contact
• Pack quantity: 10 pieces per package
• Intended function: EMI/EMC sealing between panel edges and chassis
• Installation type: adhesive-backed or mechanical compression (depending on panel design)

How to use

Measure and cut the gasket to the required lengths for the panel edges, ensuring full coverage of the contact surfaces. Clean the mating surfaces on both the panel and chassis to remove dust, oils, and loose particles to ensure reliable conductivity. Position the gasket onto the panel edge and secure it according to the panel design—either by compressing the panel into the chassis to achieve mechanical contact or by using the gasket's adhesive backing where provided. Verify continuous contact along the full perimeter after installation and adjust compression as necessary to avoid over-compression that could damage the textile fibers.

Usage recommendations

For optimal shielding performance, select gaskets covering the full mating surface and maintain even compression around the panel. Inspect gaskets periodically for wear or contamination and replace damaged pieces to preserve EMC integrity. When installing in high-vibration environments, ensure mechanical retention is sufficient to prevent displacement of the gasket.
