Utilizing the dielectric footprint of the ITT’s MD series connector and designing an aluminum shell to be a thinner lower profile package ITT has succeeded in developing a new connector family that meets all of the performance criteria of ITT’s MDM series as well as the M83513 series of connectors. The new low profile series is available in standard cable plugs and receptacles in contact sizes 9 through 51 positions. This family of connectors like the original MDM series features ITT-ICS’ twist pin contact technology on 0.050 inch spacing. This contact system has been utilized by ITT-ICS for nearly 50 years and is an excellent system under high shock and vibration loads. In addition to the cable variants, ITT-ICS also offers the new low profile series in board mount straight and condensed board right angle versions. These connectors are lower profile and take up less real estate on a PCB. The board mount designs are thru whole versions and can accommodate from 9-51 contact positions. Future versions will include surface mount designs. The performance attributes of the low profile series are the same as the MDM and Mil DTL 83513 series of connectors. These interconnects are available as complete assemblies. Also, the low profile MDM series meet high temperature requirements greater than 200° C operating temperatures for the most demanding environments.
