Federal-Mogul’s Electrical/Electronics Systems Protection Portfolio Eliminates Electromagnetic Interference (EMI)
SOUTHFIELD, Mich., March 18 /PRNewswire-FirstCall/ — As automakers continue to develop vehicles with significantly increased use of electronic controls, there is a growing need to ensure that the electrical/electronics architecture is protected against electromagnetic interference (EMI). Federal-Mogul Corporation (Nasdaq: FDML) is a leader in systems protection products for aerospace applications and has recently developed new EMI shielding products for automotive use. EMI is the unintentional generation and reception of electromagnetic disturbances traveling through a circuit or wiring harness that can cause computer-controlled systems to power-up, power-down or create a variety of other unwanted effects. EMI can be blocked using specially designed protective sleeves, thereby preventing the transmission and reception of the disturbance and its negative consequences.
“Federal-Mogul offers a complete range of electromagnetic shielding solutions that ensure EMI events do not adversely affect the function of device control systems or electronic actuators,” said Jan Maiden, engineering and sales vice-president, Federal-Mogul Systems Protection Group. The company currently provides EMI shielding solutions to leading U.S. and European commercial aircraft manufacturers and believes this unique expertise is increasingly needed for current and future automotive and commercial vehicle uses, considering the increasing use of hybrid and electric propulsion systems. “The electrical and electronic architectures of vehicles must be properly engineered and that includes proper shielding against EMI,” said Maiden.
Federal-Mogul’s EMI shielding products feature a specially-designed, braided, tinned, copper wire combined with a proprietary hybrid yarn technology that can be easily installed on existing electrical/electronic architecture used in instrument panels, engine compartments, vehicle interior systems or other electrical and electronic devices. The sleeving is available in tubular and self-wrapping constructions that can be installed during initial harness assembly or after complete vehicle systems are assembled, in the event that an EMI problem is detected and correction is required.
“EMI shielding performance is a function of metal content and metal coverage – the greater the metal content, the better the low-frequency shielding performance. However, increased metal content adds weight and doesn’t necessarily shield well at higher frequencies. High-frequency protection occurs when the metal completely covers the wire with a thin conductive layer, meaning there are no pinholes that allow the EMI to leak through.” Federal-Mogul’s hybrid yarn technology achieves a balance of low- and high-frequency shielding because the metal strands are twisted together with filler yarns, resulting in a high-strength material. “When woven or braided into sleeves, the yarns achieve an optimized blend of metal content and coverage that is lightweight, flexible and durable,” Maiden said.
Other shielding techniques, such as foil wrapping or full wire mesh over-braiding are also available in the marketplace, but can limit harness flexibility and increase overall weight, according to Maiden. Federal-Mogul’s hybrid polyester and metal wrap solutions offer a nearly 30 percent weight savings over metal overbraids, an approximately 40 percent decrease in bundle diameter and a 55 percent increase in overall flexibility, thus facilitating harness routing inside the vehicle.
Federal-Mogul EMI shielding products are engineered, designed and tested at the company’s Systems Protection technical centers in Exton, Pa., USA and Crepy-en-Valois, France, and are sold under the Federal-Mogul and Bentley Harris brand names.
