Case Studies: EMI/RFI Shielding Applications

	Portable Telemetry Device Apogee's telemetry products are used for testing bit error rates and data links on satellite displays and rocket launches.
	Printer Base "Our point-of-sale printers sit side-by-side with other electronic equipment," explains Chris Webber, Supplier Engineer at Axiohm Transaction Solutions. "They need to be properly shielded so they don't give off or react to interference created by these neighbors."
	Optical Encoder High performance optical encoders convert mechanical rotary motion in motors, shafts, and conveyors into electrical signals that are monitored by computers.
	Microcell Radios Ricochet, a division of Metricom, Inc. of Los Gatos, CA, has developed a wireless modem and Internet service for on-the-go professionals using lap-top computers.
	Connector Hood Positronic Industries of Springfield, MO and RTP Company teamed-up to meet shielding requirements for a connector hood.
	Cell Phone Gasket RTP Company has developed a new material which provides electromagnetic and radio frequency interference(EMI/RFI) shielding and is pliable enough to serve as a gasket or seal.
	Tape Drive Covers IBM Storage Systems Division in Tucson, AZ and RTP Company teamed-up to find a specialty compound ideal for front and back covers of the IBM Magstar Tape Drive operator/service display panel.
	Electronic Book Enclosure An electronic book by IBM of Rochester, Minnesota which utilizes an RTP Company material, took top honors in Plastics Industry News magazine's Computer & Business Equipment Category.
	Multimeter Shield Molded conductive composites for EMI/RFI shielding are most difficult to qualify by pre-assembly testing. Several methods are useful for ranking or comparing candidate materials.
	Gas Sniffer An RTP Company stainless steel reinforced ABS compound snuffed out a competitive metal as the best material for a gas monitor application.
