MAJR Products Home Page

Our product line primarily consists of conductive gaskets, form-in-place gasketing, shielded tents, sticky fingers, elastomers, electromagnetic interference (EMI) windows, board level (EMI/RFI) shielding, and air ventilation/filtration panels. These products reduce or eliminate EMI/RFI "noise" associated with electronics and are usually installed in or on the enclosure or cabinet that contains the working electronics.

Fingerstock Products
MAJR FingerstockOur fingerstock gasketing made of Beryllium Copper is ideal for repeated opening and closing applications where high attenuation performance and mechanical strength is required. Beryllium copper's electrical properties provide shielding effectiveness over an extremely broad frequency range. Mechanically, Beryllium Copper yields a high deflection range, with low compression set. Beryllium Copper, alloy 25, is used for maximum spring properties of strength and fatigue resistance. A variety of fingerstock is also available in stainless steel. We feature RoHS Compliant Material, High EMI/RFI Attenuation, variety of platings and finishes and high temperature tolerance.
Board Level Products
MAJR Custom Board Level ShieldingMAJR specializes in the design and production of custom shielding solutions, shielding cans manufactured specifically to meet the requirements of exact EMI/RFI applications. Using precision Photo Etching techniques, MAJR can supply custom tailored solutions in a matter of days, so there can be little justification for maintaining stocks of cans with compromised, standard, design and dimensions. Ideally, cans should be designed to suit the application and not vice versa. This 'custom' approach is essential if functionality and the use of 'real estate' are to be optimized. MAJR has successfully assisted dozen's of companies in the co-design of shielding for board level explicit problems.
Thermal Management
MAJR Thermal ManagementMAJR 6000 thermal management materials consist of sheet, adhesive, and grease compounds; these thermal materials are used in a wide variety of markets such as chip sets for IC controller packages, IT for industrial and personal computers, DRAM Modules, telecom devices, automotive control units, and a variety of other products used in military and commercial markets.
