Higher signal speeds require new levels of radiation emission protection. In order to accommodate more effective shielding performance ITT-ICS introduces a new family of EMI protective MDM series of connectors and cable assemblies. This new family of shielded connectors incorporates the highly successful ITT-ICS micro twist pin contact system for superior electrical signal and mechanical performance. In addition, the new design utilizes an EMI ground spring on the pin side connector as well as an integrated back shell for shielding terminations on the back end. The ground spring is gold plated offering superior EMI protection. The connector family is available from 9 contact positions thru 51 contact positions and meets the performance requirements of Mil DTL 83513. The new EMI MDM series is offered in cable assemblies which can be provided as pigtail or end to end assemblies. These assemblies provide flexibility as to wire types and can be provided in twisted pairs. Cable types will typically include an overall shield braid that can be easily terminated directly to the connector.
