Quick-Shield：EMI Spiral Shielding Gaskets with Excellent Spring Back

Quick-Shield strikes the perfect balance between high performance and cost-effectiveness in electromagnetic interference (EMI) protection. This spiral gasket solution offers engineers a practical and reliable answer to EMI shielding challenges, without exceeding budget constraints. Its intelligent design focuses on delivering essential functionality with minimal complexity, making it an ideal choice for a wide range of electronic applications requiring consistent EMI compliance.

Core Advantages of Quick-Shield

The strength of Quick-Shield lies in its thoughtful engineering. Crafted from spring-tempered stainless steel, the gasket maintains excellent spring memory and resistance to compression set. This guarantees long-term, consistent performance—even in applications involving frequent access or operation.

The spiral construction creates multiple contact points upon compression, forming highly effective electromagnetic seals across enclosure interfaces. Combined with the inherent durability of stainless steel, this design offers a robust solution capable of withstanding demanding environmental conditions while preserving shielding integrity.

Performance Specifications

Quick-Shield provides reliable EMI shielding, typically exceeding 95 dB at 1 GHz. While actual performance may vary based on application-specific conditions, this level of protection meets the common requirements of commercial and industrial electronic equipment. The gasket effectively aids compliance with FCC and European Community EMI regulations.

This performance is achieved through an all-metal spiral construction that maintains stable electrical characteristics over time. Unlike composite materials that may degrade, Quick-Shield ensures consistent and durable shielding throughout its service life.

Flexible Configuration Options

To accommodate diverse application needs, Quick-Shield is available in three compression force variants:

• Standard Kraft – for robust applications
• Mäßige Kraft – for general-purpose use
• Geringe Kraft – for delicate structures

This flexibility allows designers to select the ideal resiliency level for their mechanical requirements. Optimal compression is achieved at 25% of the spiral diameter, ensuring effective sealing with manageable closure forces.

Practical Implementation

The groove-mount design streamlines installation and enhances reliability. When used with die-cast or molded “pinch boss” grooves, the system delivers outstanding price-to-performance value. This mounting approach ensures secure placement and proper alignment during operation.

For applications where over-compression is a concern, corded versions are available alongside the standard no-cord configuration. The product also supports customization, with diameters ranging from 0.034″ to 1.5″, and passivated stainless steel versions for improved corrosion resistance.

Now available in passivated stainless. Please contact us for ordering details.

Additionally, silicone cord inserts are offered in multiple color options—including orange, gray, and transparent. This color-coding system aids visual identification during assembly and maintenance, while retaining all the mechanical and shielding properties of the standard configuration.

Applications and Value

Quick-Shield is well-suited for a variety of electronic applications where both cost-effectiveness and dependable performance are essential. Its balanced approach to EMI protection makes it particularly valuable for volume production projects that demand consistent quality and predictable costs.

By combining stainless steel construction, a proven spiral design, and flexible configuration options, Quick-Shield provides engineers with a practical and reliable tool for addressing electromagnetic compatibility challenges. It demonstrates that effective EMI protection does not require complex or costly solutions when core requirements are met through intelligent engineering.
