Robert McKeown Co., Inc. - Low Closure Force EMI Gaskets - Selector Guide

Soft Shield commercial-grade EMI gaskets are designed for shielding and grounding in today's commercial electronic enclosures. They consist of an electrically conductive fabric jacket over a highly compressible urethane foam core. Nickel-plated-silver, woven nylon rip-stop jacket is self-terminating when cut. A broad range of highly compressible profiles are available as strips or kiss-cut parts, in both UL 94V-0 and General Duty versions. Pressure-sensitive adhesive attachment tape is provided standard for easy application.

¹ PSA typically covers less then 50 % of contact area. Upon compression the conductive fabric will make direct contact to the interface.
