Flat Cable Connectors XG4 41
Flat Cable Connectors
XG4
Industry Standard Circuit Board
Connectors Conform to MIL Standards
XG4M-U: Unique locking system, with lock levers on strain
relief / socket instead of on plug, saves 24% of space
Space-saving Box-type Plugs (XG4C) available.
Can be used with XG5 IDC Connectors for discrete wires, XG8
Original PCB Plugs, and the XG2 IDC Bus Connectors for PCBs.
The Original Plugs (XG8) and the Box-type Plugs (XG4C)
can be locked using External XG5Z and XG4Z Lock Levers.
Conforms to MIL standards (MIL-C-83503).
UL recognition (file No. E103202)
Ordering Information
Note: 1. XG4M can be provided with or without the strain reliefs;
XG4M-U consists of XG4M-@@3@socket +XG4U-@@04 strain relief
XG4M-T consists of XG4M-@@3@socket + XG4T-@@04 strain relief
2. XG4H PCB mount socket mates with XG4C and XG8W (see XG8 Datasheet) for board to board connectivity without cables.
3. XG5 connectors (see XG5 Datasheet) use discrete wire instead of flat ribbon cable.
4. XG4A PCB mount sockets are available with Long, Short or no Lock Levers.
5. Optional XG4Z-001@side-lock levers, purchased separately, are available for use with right-angle XG4A versions that don’t include them.
6. Optional XG4Z-0002 and XG5Z-0002 top-lock levers are available for mating XG4M(-T) sockets to XG4C and XG8 plugs.

Lock Levers for XG4A-@@3@/7@
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.
These versions of the XG4A connector 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.
Lock Levers can be used with either Straight or Right Angle
versions of the XG4A.
Ordering Information
Note: 1. The left and right Lock Levers are identical. One pair is
needed for each Plug.
2. Use Long Lock Levers when mating XG4A plug to XG4M-T
cable mount socket with strain relief or XG5M sockets for
discrete wires.
3. Use Short Lock Levers when mating XG4A plug to XG4M
without strain relief attached.

Flat Cable Connectors XG4 55
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.
Correct Use of XG4A 2-tier Plug
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 an XG5S Semi-cover before connecting the XG5M-N. It is
not possible to use an XG5S Hood Cover. (See XG5 Datasheet)

External Polarization Options
The following optional accessories can be used to provide polarization to sockets and plugs that do not have molded polarizing guides and slots
built into their housings and shrouds.
Solutions for Shrouded Connectors
XG4Z-0004 Polarizing Key
Typically, 10 contact versions of the XG4A, XG4E and XG4C are
available with or without polarizing guides.
Install the XG4Z-0004 polarizing key on XG4A, XG4E and XG4C
plugs that do not have a polarizing slot, to prevent reverse connec-
tion with XG4M cable sockets that do not have a polarizing guide.
For all other versions, the molded polarity guides and slots can be
used by themselves to help prevent reverse insertion. However, use
the polarizing key with these versions as well for best results.
Note: Each XG4Z-0004 has 4 Polarizing Keys.
Solutions for Unshrouded Connectors
Use the XG4Z-0005 coding pin to fill a specific hole in one of the
XG4 or XG5 sockets. Then, use the XY2E-0002 cutting pin to remove
the corresponding terminal from an XG8 unshrouded plug.
(See XG5 and XG8 datasheets for details about those connectors.)
XG4Z-0005 Coding Pin
Note: 1. A contact with a Coding Pin inserted 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 - PCB Mount Sockets and Plugs
Correct Use
Automated Soldering Conditions (Jet Flow)
1. Soldering temperature: 250 ±5°C
2. Continuous soldering time: Within 5 s
Note: The coding pin and cutting tools can also be used to prevent in-
correct wiring by removing different terminals from side-by-side
connectors. For example, for connector set 1, remove terminal
1 and fill socket hole 1. Then, for connector set 2, remove
terminal 2 and fill socket hole 2. This prevents socket 1 from
mating with plug 2, ensuring correct wiring.
