3M™ Mini Delta Ribbon (MDR) Interconnect Solutions

High-density, shielded interconnects for demanding industrial, imaging, and high-speed I/O designs.

3M Mini Delta Ribbon (MDR) interconnects deliver reliable, high-density performance for applications ranging from industrial equipment and motion control systems to machine vision and general high-speed I/O. Built on a 0.050 inch ribbon-style contact interface, MDR connectors support stable electrical performance and consistent mechanical retention in environments where signal integrity and durability are critical. With a long-proven performance record and comprehensive ecosystem of connectors, shells, and cable assemblies, the MDR family provides a robust foundation for high-density interconnect designs.

Key technical advantages include:

  • Shielded metal shells for EMI/ESD protection
  • Pre-loaded ribbon contacts for stable, repeatable mating/unmating
  • IDC U-contact termination enabling efficient mass-termination
  • Broad selection of wiremount, boardmount, and shell-kit options to support flexible design architectures
  • Fully shielded Camera Link and LVDS cable assemblies with controlled impedance and low signal skew
  • Rugged hardware options including thumbscrews, jack sockets, and mounting accessories for secure retention
