XG4H Board-to-board Sockets

The Mainstream of Circuit Board Connectors conforming MIL Standards with Improved Design.

  • Our new production system improves reliability.
  • Space-saving Box-type Plugs (XG4C) available.
  • IDC Plugs (XG4E) can be used for relaying.
  • An endless number of combinations can be made using the XG-5 IDC Connectors for discrete wires, XG8 Original Plugs, and the XG2 IDC Connectors for PCBs.
  • The Original Plugs (XG8) and the Box-type Plugs (XG4C) can be locked using Lock Levers.
  • Conform to MIL standards (MIL-C-83503).
  • See the "Standards certification / conformity list" for information on conformity to certification standards.
