TE Connectivity SNGS Low Hardness Conductive Elastomers

Introduction

TE Connectivity SNGS Low Hardness Conductive Elastomers are silicone-based conductive sealing materials designed to provide effective electromagnetic interference (EMI) shielding while maintaining environmental sealing performance. Their soft, low-force characteristics make them suitable for assemblies with limited clamping force or uneven mating surfaces.

Part Description

The SNGS series uses a silicone nickel-graphite formulation that combines electrical conductivity with the flexibility and durability of silicone elastomer material. With a hardness of approximately 40 Shore, these conductive elastomers can conform to component-height variations, surface irregularities, and enclosure tolerances without requiring excessive compression force.

SNGS conductive elastomers support both EMI shielding and environmental sealing, helping protect sensitive electronics from external electromagnetic noise, dust, moisture, and other environmental contaminants. They are available in extrusion and molding grades, enabling use in standard gasket profiles as well as application-specific molded seals. A PFAS-free extrusion option is also available for designs with material compliance or sustainability requirements.

Applications

Potential applications for SNGS conductive elastomers include:

• EMI shielding gaskets for electronic enclosures
• Conductive environmental seals for outdoor electronics
• Cabinet, panel, and access-door sealing
• Shielded connectors and connector interfaces
• Seals around displays, control panels, and HMI assemblies
• Aerospace and defense electronics housings
• Telecommunications equipment enclosures
• Medical-device electronics protection
• Industrial control and automation cabinets
• Automotive electronic control-unit enclosures

Usage Ideas

1. Weatherproof RF Enclosure
   Use an SNGS gasket around a radio-frequency enclosure lid to provide EMI shielding and protection against dust and moisture.

2. Industrial Control Panel Seal
   Install an extruded conductive elastomer profile around an industrial controller door to reduce electromagnetic emissions and improve environmental sealing.

3. Vehicle Electronics Housing
   Integrate a molded SNGS seal into an automotive electronic control-unit housing to accommodate assembly tolerances while supporting EMI performance.

Conclusion

TE Connectivity SNGS Low Hardness Conductive Elastomers provide a practical combination of low compression force, conductive EMI shielding, and environmental sealing. Their soft 40 Shore formulation helps compensate for height variation and uneven surfaces, while extrusion and molding options support a broad range of enclosure, connector, and electronic-system designs.
