XG4M-U MIL-type Connector with socket Lock

The mainstream of circuit board connectors, meeting MIL standards with improved design.

  • With our new production system, we have improved the reliability and decreased the cost.
  • Space-saving box-type plug (XG4C) also available.
  • Solderless plug (XG4E) can be used for relaying.
  • An endless number of combinations can be made using the discrete wire solderless connector (XG5), the original plug (XG8), and the PCB connector (XG2).
  • The unshrouded plug (XG8) and the box-type plug (XG4C) can be locked using the lock lever.
  • Conforms to MIL standards (MIL-C-83503).
  • UL standard component (file no. E103202).
