Omnidirectional Conductive

Foam

Gasket

Overview

The Omnidirectional Conductive Foam Gasket offers full three-axis (X, Y, Z) conductive contact and shielding within a compressible foam core wrapped in metallized fabric or foil. It is designed to handle complex geometries and high-density electronics, delivering superior EMI performance in enclosure seams, connector interfaces, and compact modules.

Core Features & Benefits

Three-axis Conductivity — Provides electrical contact and grounding in all directions, ideal for fine-pitch and high-speed designs.
Low Compression Force — Engineered to establish reliable contact with minimal force and accommodate tolerant assemblies.
High Shielding Effectiveness — Achieves > 90 dB attenuation across broad frequencies in compact form factors.
Durable Construction — Metallized fabric resists abrasion, shear, and repeated closure cycles, ensuring long-term reliability.
Customizable Profiles — Available in die-cut shapes, slit strips, adhesive-backed formats and designed for odd-shaped or space-constrained applications.
Compliance — Flame-retardant, halogen-free, and RoHS-/REACH-compliant options available for rigorous regulatory environments.
