Advantages

Ultra-Vanshield Dual Elastomer Shielding Gaskets Provide the Following Advantages Over Traditional EMI Gaskets with Conductive Particle Throughout Cross Section:

Resilient inner core remains free of metal fillers

  • Optimum compression and aging properties

Silver conductive material is only present in outer thin membrane

  • Excellent Conductive Properties

Thin silver layer permits reduction in costly silver content

Attenuation performance is not degraded under full compression

Very low compression force

Manufacturing flexibility

Easy termination

Single piece weather and EMI seal

  • Extended galvanic protection
  • NEMA, IP, wind driven rain, and immersion sealing protection

MicrobridgeMicrobridge™

(US Patent # 6,410,846B1 and 6,613,976B1, other patents pending)

Same advantages as Ultra-Vanshield

Offers moisture seal on both sides of conductive portion for extended galvanic protection

Further reduces silver content for better cost performance
