XG4
Flat Cable Connectors
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 compatibility and quality assurance condition of each company, MILC-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 assembly.)
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.")

Lock Levers
• This series of Connectors allows you to attach Lock Levers on
Right-angle Terminal Plugs after automated soldering is completed.
• Lock Levers can be easily mounted simply by manually pushing
them in.
Attachment after Soldering
• Long Levers interfere with automated mounting.
• Long Levers are in the way when boards are packed.
↓
• These problems are resolved using Connectors with Long Levers
that can be attached after soldering is completed.

■ Mounting Example
■ 2-tier Plug Features
• Recommended for high-density mounting.
• MIL-compliant cable ensures faster delivery times and lower cost
than half-pitch board cable. The 2.54-mm pitch simplifies patterning.

■ Precautions
Correct Use
Soldering
• Automated Soldering Conditions (Jet Flow)
Mounting
• Be sure to anchor the board with screws before mounting.
• Note that a Polarizing Key cannot be mounted on the lower Plug.
Connecting the Socket
• Before connecting the XG4M with Strain Relief, remove as much
slack from the cable as possible. Insert as shown below.
• Attach the Semi-cover before connecting the XG5M-N. It is not possible to use the Hood Cover.

Polarity guides and slots can be used by
themselves to help prevent reverse insertion. Use the Polarizing Key as well for best
results.
(To prevent erroneous insertion)
The Contact Cutting Driver is used to cut
(twist off) a contact on the mating Plug
when using an XG4Z-0005 Coding Pin.
How to use
Insert
The Coding Pin is used to prevent confusion when many Connectors with the same
number of contacts are lined up. It can also
be used to prevent reverse insertion when
using Connectors without a shroud like the
XG8 Unshrouded Plug. The Coding Pin
can also be used with XC5, and XC6 DIN
Connectors as well as with XG5 Discretewire IDC Connectors.
How to use
Twist
Insert the plug
contact into the
groove on the
Driver, and twist
off the contact
from the base.

■ Precautions
Correct Use
• Automated Soldering Conditions (Jet
Flow)
1. Soldering temperature: 250 ±5°C
2. Continuous soldering time: Within 5 s
• Soldering
Solder-mount the XG4A with the lock levers
fully closed or fully open.
Solder-mounting the XG4A with the lock
lever half-open may cause play in lock lever
due to thermal deformation of the housing.
• Storage
If the lock levers of the XG4A or XG4E connector are left at an intermediate position
for a long time, they may get to feel loose in
operation due to deterioration of the plastic
part. When the lock levers are not used,
store the plug with the lock levers fully
closed or fully open.
