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)
■Terminology
zMIL standard
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.
zOpen-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.")
zStandoff
Part provided for lifting the housing from the board (This
part improves airflow at the through-hole for better assem-
bly.)
■Ordering Information
■Ratings and Characteristics
Note: 1. The rated current will depend on the Socket you are using. It is 1 A using the XG4M for example.

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.
Note: The left and right Lock Levers are identical. One pair is needed
for each Plug.
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.

I Cable Number and Correct Use
12 Flat Cable Connectors XG4
■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 pattern-
ing.
■Precautions
Correct Use
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 pos-
sible to use the Hood Cover.
Soldering
• Automated Soldering Conditions (Jet Flow)
1. Soldering temperature: 250 ±5°C
2. Continuous soldering time: Within 5 ± 1 s
Lock Lever Operation
When you operate the lock lever, do not force it past the movable
range.
The connector may be damaged.
Do not use any type of tool to operate the lock lever. Operate it only
with your hand.
The connector may be damaged.
Always release the lock mechanism before you disconnect the con-
nector from the connected socket.
The connector may be damaged.

■Tools and Accessories (Sold Separately)
XG4Z-0004 Polarizing Key
Polarity guides and slots can be used by
themselves to help prevent reverse inser-
tion. Use the Polarizing Key as well for best
results.
Note: Each XG4Z-0004 has 4 Polarizing
Keys.
XG4Z-0005 Coding Pin
(To prevent erroneous insertion)
The Coding Pin is used to prevent confu-
sion 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 Discrete-
wire IDC Connectors.
Note: 1. A contact with a Coding Pin in-
serted cannot be used.
2. Each XG4Z-0005 has 4 Polarizing
Keys.
XY2E-0002 Contact Cutting Driver
The Contact Cutting Driver is used to cut
(twist off) a contact on the mating Plug
when using an XG4Z-0005 Coding Pin.
■Precautions
Correct Use
• Automated Soldering Conditions (Jet
Flow)
1. Soldering temperature: 250 ±5°C
2.
Continuous soldering time: Within 5±1 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 con-
nector 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.
