3M Interconnect Products MDR Connector Selection Guide 3High Density Input/Output Connectors 3M Mini Delta Ribbon (MDR) Connectors Performance and Reliability in Miniature The Mini Delta Ribbon (MDR) is a half pitch interconnect system from 3M, designed to meet the needs of high speed/density input/output applications. With more than 20 years on the market, the MDR system is an established and well-proven solution for high density I/O. MDR enjoys widespread acceptance by offering a combination of design features: n Shielded shells provide EMI/ESD protection n Pre-loaded ribbon contacts provide proven reliable connection n IDC U-shaped contacts allow mass termination n Wide range of pin counts and form factors enable design flexibility As one of the worlds most innovative companies, 3M is continually developing its products to meet your I/O needs. The current range of MDR system components can easily be expanded to meet the specific requirements of a broad range of applications. The MDR connector system contains a ribbon-style contact based on 0.050 centerlines. Both the receptacle and the mating plug contain pre-loaded contacts for reliable contact during insertion and withdrawal cycles. The cable connectors utilize an insulation stripping U-contact to connect to the cable conductor wires. The contact is stamped from a high performance copper alloy, which provides an excellent combination of mechanical strength, electrical conductivity and corrosion resistance.
