MM and MB series

View Products

Qualified per MIL-C-28748 requirements, the MM and MB series are miniature and sub miniature connectors used in civil and military applications such as in-flight equipment, instrumentation or missile. These rectangular multicontact connectors offer:

  • Ruggedness
  • High performance
  • High contact density
  • Weight and space saving design
  • High vibration and shock resistance

An interconnect solution for electric and electrical equipment, MM and MB series are fitted with non-removable solder type contacts. Originally developed for rack and panel assemblies, they can be adapted for cable-to-cable applications with a cable clamp backshell.
