As the originator of the fabric-clad foam EMI shielding technology, Schlegel EMI is the industry’s most trusted name. We continue to set the standard for quality and innovation, designing advanced solutions for a wide range of applications. And our worldwide locations ensure that you get what you need, when you need it.
Modern electronic equipment often requires EMI Gaskets to avoid radiating EMI/RFI suspeptibility to outside sources of EMI/RFI. Maintaining electromagnetic compatibility can be an increasing challenge of the designers of today’s electronic and electrical products.
Schlegel Electronic Materials, Inc. (SEM), the preeminent manufacturer of fabric over foam EMI shielding products for the computer, telecommunications, and electronic industries, offers a full range of EMI shielding products–including gaskets, I/O backplane shielding gaskets, and highly conductive envelopes, tapes and laminates.
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).
Design and Consultation
SEM can offer a design and consultation service to help you to design filters for your display requirements. Displays are used in all applications from public information, through to man machine interfaces. This means that the physical properties of a filter will vary to suit its performance needs.
Consideration will often need to be given to several characteristics, including: impact resistance, solvent and abrasion resistance, reflection control, fire specifications, U.V. resistance or protection, RFI shielding, ESD, anti – static and anti – mist.
Filters can be designed to incorporate several characteristics in one part, and material selected from allyl carbonate, acrylic, polycarbonate, polyester and glass.
If a filter is designed correctly it can reduce cost, improve the readability of the display and allow your product to look at it’s best for a long time.
A display filter is the part of your equipment, which is looked at for the majority of its life. If badly designed it can have a detrimental effect on the performance of your product.
Optical Filters and Fascia Panels
SEM supplies high quality optical filters and fascia panels. These products are manufactured to suit individual customer requirements or specifications and can be made from allyl carbonate, acrylic, polycarbonate and glass. All filters can be manufactured to include screen printing and RFI shielding, (see technical information “RFI / EMC Filter windows” if necessary).
Filters can be manufactured to include many characteristics including ; contrast enhancement, reflection control, impact strength, fire specifications, abrasion and solvent resistance, polarisation and combinations of properties.
