Mounts to all MIL-DTL-38999
The universal header assembly from
Amphenol provides for easy separation
of the connector from the board.
The header assembly is comprised of
a short pin/socket contact. The tail end
of the contact is soldered to the through
hole of the ex or printed circuit board.
The socket is embedded in the insulator,
making electrical contact with the printed
circuit tail of the connector.
Features and Benefits:
• Circular and square header assemblies available
• Cost and time savings in the manufacturing process
• Assemblies can be vapor phase or wave soldered to ex/printed
circuit board
• Allows electrical testing when installed properly.
• Connector assemblies can be easily removed from and reattached
to the header assembly.
Mounting Applications
• Amphenol square universal headers are slotted to allow mounting to
all series of MIL-DTL-38999 or MIL-DTL-26482 connectors without
special alterations.
• Amphenol circular universal headers are designed to accommodate
the rear flange of PCB Board Mount shells, series
MIL-DTL-38999 connectors without special alterations.
• The header assembly can be attached to connectors with standard
ange placement or directly to the circuit board.
• Connectors with dual ange mounting hardware can be provided to
allow easy mounting to the panel or the header assembly.
- Forward ange would mount the connector to the panel
- Rear ange would be used to mount to the header assembly.
• Various types of captivated or loose attaching screws can be utilized
for unique applications.
* For information on Header Assemblies for MIL-DTL-26482 connector,
consult Amphenol Aerospace.
Mounting to Rectangular ARINC
Connectors
• Headers for ARINC connector arrangements
accommodate up to 150 pins
• Consult Amphenol Canada, Ontario for
ARINC congurations.
Materials
• Body is molded or machined from FR-4.
• Electrical engagement areas of the header
contact are plated with .00003 inches
minimum of gold over .00005 inches
minimum of nickel.
See drawing of standard header on next page.
Headers provide easy
separation of the
connector from the PC board.

Where 2 or 3 tools are listed for a contact size, only one tool and its die or
positioner are required to crimp the contact. The above crimping tools and
positioners are available from the approved tool manufacturer.
The following data includes information pertaining to the appli-
cation tools which have been established for crimping, inserting,
and removing contacts incorporated in the TV, CTV and MIL-
DTL-38999 Series III connectors. For additional information on
coax, twinax and triax contact tools, see High Speed Contact
section of this catalog.
All crimping tools included are the “full cycling” type and
when used as specied in the installation instructions
L-624 covering the TV, CTV and MS series connectors,
will pro vide reliable crimped wire to contact terminations.
There is a possibility of additional crimping tools other
than those included being available at present or in the
future for this specic appli cation.

** Min. diameters to insure moisture proof
assembly; max. diameters to permit use of metal
removal tools.
1. Strip wire to required length. (See Figure at right). When
using hot wire stripping, do not wipe melted insulation ma-
terial on wire strands; with mechanical strippers do not cut
or nick strands.
2. See Table 1 for proper nished outside wire dimensions.
3. Twist strands together to form a rm bundle.
4. Insert stripped wire into contact applying slight pressure until wire insulation
butts against wire well. Check inspection hole to see that wire strands are vis-
ible. If there are strayed wire strands, entire wire end should be re-twisted.
When wire is stripped and properly installed into contact, the next step is to
crimp the wire inside the contact by using the proper crimping tool.
Crimping
See table on preceding page for recommended
M22520 series crimping tools, turret head
or positioner selection settings according to
contact size, part number and wire gauge size.
VISUAL INSPECTION
HOLE
1. Insert stripped wire into contact crimp pot.
Wire must be visible through inspection
hole.
2. Using correct crimp tool and locator, cycle
the tool once to be sure the indentors are
open, insert contact and wire into loca-
tor. Squeeze tool handles rmly and
completely to insure a proper crimp. The
tool will not release unless the crimp
indentors in the tool head have been
fully actuated.
3. Release crimped contact and wire from
tool. Be certain the wire is visible through
inspection hole in contact. Examples of M22520 Series Crimping Tools:
Shown top: tool used for small size 22, 22D
and 22M contacts.
Shown bottom: tool used for size 20, 16 or
12 contacts and has a positioner that can be
dialed for each contact size.
Contact Insertion
1. First remove hardware from the plug
and receptacle and slide the hard-
ware over wires in proper sequence.
2. Use proper plastic or metal insertion
tool for corresponding contact. (Con-
sult Insertion Tool table on preceding
page). Slide correct tool (with plastic
tool use colored end) over wire insula-
tion and slide forward until tool bottoms
against rear contact shoulder.
3. Next align the tool and contact up
to the properly identified cavity at
rear of connector plug. Use rm,
even pressure; do not use exces-
sive pressure. It is recommended
to start at the center cavity. Contact
must be aligned with grommet hole
and not inserted at an angle. Push
forward until contact is felt to snap
into position within insert.

Installation Instructions, cont.
Contact Insertion, cont.
4. Remove tool and pull back lightly
on wire, making sure contact stays
properly seated and isn’t dragged
back with the tool. Repeat operation
with remainder of contacts to be
inserted, beginning with the center
cavity and working outward in alter-
nating rows.
5. After all contacts are inserted,
ll any empty cavities with
wire sealing plugs. (Refer to
sealing plug charts for Series
III on page 18, for Series I & II
and SJT see page 19.
6. Reassemble plug or receptacle hardware
- slide forward and tighten using connec-
tor pliers. Connector holding tools are
recommended while tightening back ac-
cessories. When using strain relief, center
wires at bar clamp. Slide clamp grom-
met into position and tighten clamp bar
screws. When tightening screws, pressure
should be applied in the same direction
that clamp is threaded to rear threads of
connector. When not using clamp grom-
met, build up wire bundle with vinyl tape
so clamp bar will maintain pressure on
wires.
CAUTION, when inserting or removing contacts, do not
spread or rotate tool tips.
Contact Removal
1. Remove hardware from plug or
receptacle and slide hardware back
along wire bundle.
2. Use proper plastic or metal
removal tool for correspond-
ing contact. (Consult Removal
Tool table on page 135). Slide
correct size tool over wire
insulation.
3. Insert plastic or metal removal tool into
contact cavity until tool tips enter rear
grommet and come to a positive stop.
Hold tool tip firmly against positive stop on
contact shoulder. Grip wire and simultane-
ously remove tool and contact. (On occa-
sion, it may be necessary to remove tool,
rotate 90° and reinsert.)
Use white end of plastic tool for
removal of contacts.
