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).
UL standards (file No. E103202) (All XG4 models
except those with XG4U)
RoHS Compliant
Terminology
• MIL standard
Abbreviation for Military Standard. To unify the compatibility and quality assurance condition of each company, MIL- C-83503 (applicable to connectors) was established in 1977.
• Open-end cover
An open-end cover has a structure where a flat cable can be pulled out from both sides of the cover when a cable is attached to a connector. (The cover having a structure where a flat cable can be pulled out from only one side of the cover is called a "Closed-end cover.")
Standoff
Part provided for lifting the housing from the board (This part improves airflow at the through-hole for better assembly.)
