Flat Cable Connectors
XG4
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 and XG4H)
RoHS Compliant
■Terminology
z MIL standard
z Standoff
Abbreviation for Military Standard. To unify the compatibil-
ity and quality assurance condition of each company, MIL-
C-83503 (applicable to connectors) was established in
1977.
Part provided for lifting the housing from the board (This
part improves airflow at the through-hole for better assem-
bly.)
z 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.")
