Rigid Frame EMI Gaskets
Series No. 3000
MAJR Products’ rigid frame EMI gaskets consist of an aluminum extrusion with a specially designed jaw. When closed, the jaw crimps the fin of the knit wire EMI gasket to form a rigid construction with the EMI gasket held firmly in place.
Using MAJR’s rigid frame EMI gaskets allows for mechanical mounting in problem areas for cabinets and enclosures including doors and access panels that need EMI/RFI shielding that are frequently opened. The rigid frame gasket is designed to control compression on the chosen gasket material ensuring the gasket material doesn’t take a compression set over time. It also acts as a mounting surface allowing the use of bolts or screws to secure the gasket to a flange instead of relying on adhesives which can degrade quickly in harsh environments.
Overview
MAJR Products’ rigid frame EMI gaskets consist of an aluminum extrusion with a specially designed jaw. When closed, the jaw crimps the fin of the knit wire EMI gasket to form a rigid construction with the EMI gasket held firmly in place.
MAJR’s Rigid framed design provides a gasket assembly that can be installed with flat-head screws. This design makes retro-fitting in the field a relatively easy task while at the same time providing a positive stop for controlled compression of the EMI gasket.

Product Features
Built to your specifications: MAJR’s engineering team will work with you to design a Rigid Frame EMI Gasket to meet your custom requirement.
Versatility of Materials: MAJR provides the standard knit wire mesh in either monel, tin-plated ferrous or knitted mesh over core as well as conductive elastomer profiles to best accommodate your requirement.
High EMI/RFI Attenuation Levels: The highest possible attenuation levels are achievable with MAJR’s EMI/RFI knitted wire gasketing. Attenuation levels beyond 110 dB in the E-Field and 65 dB in the H-Field are common with MAJRís EMI shielding gasketing. Higher levels of attenuation are attainable with special materials and special design available through MAJR’s engineering team.
Resilient Gasketing Material: MAJR’s knit wire gasketing material acts like thousands of tiny spring members which are compressed and released with each opening and closing of a cabinet door or enclosure cover. The spring-look gaskets assure long life with consistent point-to-point contact, providing high shielding effectiveness and long life.
