Selected Manufacturers | Schlegel EMI
EMC / RFI Shielding | Thermal Management
Schlegel Electronic Materials (SEM) invented highly conductive fabric over foam shielding gaskets in 1987, marking a major breakthrough for the electromagnetic interference shielding of electronic enclosures and has become the pre-eminent manufacturer of electromagnetic interference (EMI) shielding products.
SEM offers a full range of EMI shielding products including gaskets, I/O backplane shielding gaskets, BeCu Fingerstock, and conductive tapes and laminates. These enable the computer, telecommunications, military, medical and electronics industries to meet global requirements for electromagnetic compatibility (EMC).
From concept to production, SEM’s complete portfolio of shielding products combines highly conductive materials with flexible foams and coatings to provide the latest EMI containment solutions.
The company’s world-renowned EMI shielding gaskets are available in hundreds of profiles and unique designs, with attachment options that include mechanical self-attaching, clip, rivet, and a variety of pressure-sensitive adhesives.
Elastomers & Silicone Gaskets
Schlegel Electronic Materials, Inc. (SEM) line of silicone gaskets provides shielding capability in diverse markets and applications, including the military, aerospace, medical, fluid seal, environmental and microwave applications. Our silicone elastomers are specifically designed for gasketing applications that require high levels of attenuation up to 120 db.
Conductive Foam
Schlegel Electronic Materials, Inc. (SEM) introduces a new line of EMI foam, CF Conductive Foam. SEM CF Foam, a highly resilient Nickel-Copper polyurethane foam is sandwiched between SEM’s knitted and non-woven fabrics to form industry-leading die-cut gaskets. Conductive Foam material is ideal for applications that require conformity with excellent cavity-to-cavity EMI shielding, superior conductivity at low compression forces and better effectiveness at very high frequencies. EMI foam-based gaskets are precision die-cut with either conductive or non- conductive pressure-sensitive adhesive (PSA).
HC Filters
All frame stylescan be supplied with a conductive gasket to provide the best electrical contact between the frame and mating metal surface.
Standard tolerances for overall Finished Vent Dimensions are +/- 0.8mm
Standard tolerances on Hole Centres are +/- 0.4mm
Typical corner radii on frame styles 1701, 1703, 1705, 1706 & 1707 are R3.0mm
Shielding Windows
SEM is now proud to introduce a complete line of quality Shielded Windows. The addition to SEM’s extensive portfolio of shielding products allows SEM to be your exclusive EMI shielding supplier, to help you meet or exceed your global requirements for electromagnetic compatibilty (EMC).
Thermal Interface Materials
The OpTIM® thermal interface materials by Schlegel, offer a wide range of thermal performance and physical properties and can resolve even the most challenging thermal problems. Our TIMs are used widely for demanding applications, including advanced microprocessors, high-speed memory modules, micro heat pipe assemblies, and LED lighting.
