TE Connectivity SNGS Low Hardness Conductive Elastomers

Introduction

TE Connectivity SNGS Low Hardness Conductive Elastomers are silicone-based conductive materials developed for applications that require both electromagnetic interference (EMI) shielding and environmental sealing. Their soft construction helps designers create reliable seals while using relatively low compression force.

Part Description

SNGS conductive elastomers combine silicone with nickel graphite conductive filler material. The resulting compound provides electrical conductivity for EMI shielding while retaining the flexibility and sealing characteristics associated with silicone elastomers.

With a 40 Shore hardness rating, these materials are softer than many conventional conductive gasket materials. This low-hardness construction can help accommodate enclosure tolerances, uneven mating surfaces, and component height variation. It can also reduce the force required to compress a gasket or seal during assembly.

TE Connectivity offers SNGS materials in extrusion and molding grades, supporting a range of gasket profiles, custom seals, formed components, and other enclosure-interface designs. These conductive elastomers are suited to assemblies where protection against electromagnetic emissions or susceptibility must be combined with resistance to environmental contaminants.

Applications

Potential applications for SNGS Low Hardness Conductive Elastomers include:

• EMI shielding gaskets for electronic enclosures
• Environmental seals for control modules
• Conductive seals around display housings
• Shielded connector interfaces
• Cabinet and panel-door gaskets
• Sealing interfaces for automotive electronic modules
• Medical equipment enclosures
• Data communications hardware housings
• Energy-storage and power-electronics enclosures
• Telecommunications equipment seals
• Ruggedized sensor housings
• EMI-sealed access panels and covers

Industries

SNGS conductive elastomers may be used in a variety of industries, including:

• Automotive and electric vehicles
• Medical devices and healthcare equipment
• Data centers and networking infrastructure
• Telecommunications
• Industrial automation
• Aerospace and defense
• Energy generation and storage

Usage Ideas

1. EMI-Sealed Automotive Control Unit
   Use an extruded SNGS gasket around an electronic control unit cover to help provide EMI shielding and environmental sealing while accommodating housing tolerance variation.

2. Shielded Medical Device Enclosure
   Integrate a molded conductive elastomer seal into a portable diagnostic instrument enclosure to support low-force assembly and help control electromagnetic interference.

3. Data Center Network Switch Gasket
   Apply a conductive gasket around a network switch access panel or chassis opening to reduce EMI leakage while maintaining a flexible serviceable seal.

Conclusion

TE Connectivity SNGS Low Hardness Conductive Elastomers provide a practical material option for designs requiring EMI shielding and environmental sealing in the same interface. Their soft 40 Shore construction, low compression-force requirements, and availability in extrusion and molding grades make them suitable for electronic enclosures, connectors, panels, and modules across automotive, medical, data, energy, and industrial applications.
