BRUSH CONNECTOR ROW AND CAVITY
IDENTIFICATION
Contact rows and cavities are identied with molded-in
letters and numbers respectively and, depending on the
connector style, are located either on the front, rear or
both faces of the connector. See illustration at right.
Note: The brand name of Bendix may appear molded-in on
connectors. As manufacturing molds are remade, the correct
Amphenol name will replace the former Bendix name.
As shown in the second illustration at right, row identica-
tion is always at the radius end and begins with Row “A”.
Contact cavity identication always starts at radius end
and begins with cavity #6 and then every fth cavity
thereafter, except for arrangements consisting of 10
contacts per row, which lack numerals. Up to every 9
contact locations at the high numeral end of the contact
row will not be identied.
Mother Board and PC Connectors
Contact rows are identied on the front and rear faces.
Contact cavities are identied on the rear face.
Daughter Board Connectors
Contact rows and cavities are identied on the front face.
Input/Output Connectors
Contact rows and cavities are identied on the rear face.

General information follows on this page and the next three pages
for assembling connector accessories with Amphenol® Low
Mating Force B3 Brush Contact Connectors.* Provided are
suggestions for proper connector installation that will help to
maintain connector straightness after equipment assembly.
Low mating force connector bodies are intentionally designed to
be non-rigid to facilitate application variables such as compliance
to printed circuit boards, xtures and card cages, vibration and
shock exposure, thermal excursions and differential expansion
characteristics. Users may employ installation procedures that
will provide mating surface straightness of these non-rigid bodies
within 0.010 inch to ensure maximum connector performance.
Generally, no external board support structures are required with
B3 brush contact connectors as long as the mounting surface
offers sufcient rigidity. However, longer installations should
consider external support to prevent excessive exing of the
connector/printed circuit board assembly.
* Installation Instructions for B3 Low Mating Force Connectors had
formerly been covered in publication L-1220. This has been discontin-
ued and all installation instructions are covered here on pages 24-29.
CONNECTOR ACCESSORIES THAT ARE USED WITH B3
BRUSH CONNECTORS INCLUDE:
Locking screws for •I/O connector mounting to board
Locking/mounting bushings: •
• for PC connector mounting to board or mating to I/O
connector
• for MB connector mounting to board or mating to I/O
connector
Polarization keys for each style connector provide up to • 256 different key locations for alternate keying
Test Probe kits for ensuring that contacts are properly • wired within a connector and to prevent damage to brush
contacts during probing.
For How to Order Accessories see page 5.
B3 brush PC style connectors are shipped with PC tail combs
that not only protect the tails during shipment, but aid the
person assembling the connectors to boards to align the
contacts.
Refer to page 2 of this catalog for illustration of the connector
styles and how they mate.

Low Mating Force Connector Accessories
test probe kit
In order to insure that contacts are properly wired
within a connector, a Test Probe Kit is needed (Part
number to order is 11-10400-22). This kit is espe-
cially designed to prevent damage to brush contacts
during probing. It con sists of a plastic holder, insert,
and two contacts, usable for either Mother Board or
Daughter Board applications. It is recommended
that the user buy two kits, if using connectors of two
genders. The kits are not convertible after assem-
bly.
Instructions:
DB-IO Test Probe - Slide the insert back over the
wire and crimp contact on.
Follow crimping proce dure
below. Then snap the insert
and contact assembly into
the holder.
MB-PC Test probe - Slide holder over wire and
then crimp contact. Follow
crimp ing procedure below.
Slide the insert on the
contact and seat it against
the shoulder. Slide the
holder forward and snap it
onto the insert.
Crimping Procedure: Using accepted industry
pro cedures, strip wire end to be terminated 1/8 to
5/32 inch. Care should be taken not to nick wire
strands. Assemble the M22520/2-01 crimp tool and
the M22520/2-27 positioner, and place tool selector
in correct setting for wire size. Selected wire size
must not have an insulation diameter more

BRUSH CONNECTORS USER APPLICATION
INFORMATION
The Brush B3 connector is a highly sophisticated, innovative low
mating force device designed to provide a multiplicity or highly
redundant number of contact sites for high density, high
performance applications. Contact resistance is stable and low,
approximately 1/3 lower than the most widely available contem-
porary two piece printed circuit card connector type. To maxi-
mize the B3 connector capability and assure the greatest
potential reliability, several guidelines should be followed.
Ideally, connectors should be fully mated and not used as a
packaging system tolerance absorber. Full mating occurs when
the two molded thermoplastic contact housings (connector
bodies) touch, plug skirt to receptacle shoulder over the entire
length of the connector. However, manufacturing tolerances and
user installation procedures must be considered and can be
expected to prevent the “ideal” situation.
Connector bodies were intentionally designed to be non-rigid as
permanent exibility is necessary to allow compliance to user
printed circuit cards, xtures and card cages. Vibration and
shock exposure, thermal excursions, contact repairability, and
differential expansion characteristics further dictate the desir-
ability of exible connectors.
Amphenol drawing call-outs of part atness to a 0.010 inch FIM
(Total Indicator Reading - Full Indicator Movement) over the
mating surface length is to be interpreted as in an “as used”
condition. Rigid mounting of Mother Board (plug) parts to
frames, multi-layer printed circuit boards or back panels should
consider the need for the 0.010 inch maximum condition after
soldering or solderless wrapping procedures.
Normal Mother Board parts in an unrestrained, unused condition
may exceed the “as used” 0.010 inch reading at normal ambient
or storage environments. Thermal cycling may further aggravate
or adjust the condition. These parts present a prole from at to
a “smile” appearance when viewed from the side with the mating
surface uppermost. (For example, see photo above). Normal
positioning of this part on the Mother Board with slight restraint
through use of mounting hardware or standard mounting bolts
will automatically allow part compliance to the atness condition
of the board. Slight restraint is urged to allow for differential
thermal expansion compensation during preheating and
soldering operations. Final torquing or permanent fastening
should be effected after cool down and thermal neutralization.
Normal solderless wrapping procedures could ignore the
differential expansion consideration.
Daughter Board connectors present the same at to “smile”
prole in a free state with the mating surface downward. The
relief shelf can be used as a reference or guide when used with
a straight edged Daughter Board or printed circuit board “page”.
Once proper positioning is veried and contact tails are solder
xed to the plated through holes, straightness will be perma-
nently retained.
Low Mating Force Connector Installation
DAUGHTER BOARD AND MOTHER BOARD
FULLY MATED CONDITION
Users are urged to monitor the quality of connector installation
to optimize the mating of connectors.
During usage and when mated the worst case condition of the
“as used” 0.010 inch maximum reading of both the plug and
receptacle could cause a maximum gap between plug and
receptacle moldings of 0.020 inch. This condition is well within
the B3 product mated performance goals as our minimum
effective electrical contact engagement has greater than a
100% safety factor. Users are urged to monitor the quality of
connector installation to optimize the mating of connectors.
Input/Output connectors also normally exhibit a at to “smile”
prole with the mating surface downward. This “smile” condition
self corrects once mated with the Mother Board counterpart and
accessory locking screws are fastened. Again, checking for the
0.020 inch maximum gap is urged as a quality control monitor of
user application techniques.
Amphenol has attempted to design in the ultimate for connector
compliancy and self-correction during normal user installation
procedures. The connector capabilities and inherent reliability
rely in part on practical user procedures and application
considerations. Refer to pages 27 - 29 for other installation
instructions. And, refer to page 2 for correct mating of low
mating force connectors. Amphenol board level engineers and
product specialists are available to assist the user with applica-
tion recommendations and processing guidance. Give us a call
at 607-563-5011 and ask for board level technical assistance if
further information is needed.

MOTHER BOARD CONNECTOR
MB connectors that are mounted on printed circuit boards should be
installed on the board and held somewhat loosely, yet assuring all
connector molding standoff pads contact the surface of the board,
prior to soldering. There are several methods for attaching the MB
connector to the board.
Inserting locking/mounting bushings with an arbor press is shown in
the top photo at right. Locking/mounting bushing accessory, two per
connector, may be inserted into 0.185 inch diameter CSK holes at
each end of the front of a MB connector body. (Part number to order
locking/mounting bushing is 10-41196-3). Using a light arbor press
or similar device, rmly press the knurled section of the bushing into
the lower 0.122 inch diameter hole until the front of the bushing is
ush with, or slightly below, the front surface of the MB connector.
Refer to Figure 1 at right.
Make sure the bushing and hole axis are properly aligned. Avoid
excessive force which may crack the back surface of the MB
connector body.
The back of the locking/mounting bushing has a 4–40 UNC-2A THD
to mount the connector. Fasten the connector with a suitable washer
and nut. The front of the locking/mounting bushing has a 4–40
UNC-2B THD which will mate with the locking screw accessory of an
IO connector.

When a Daughter Board is mated, use a 4–40 screw of appropriate
length with a suitable washer under the head. Insert the screw from
the front of the connector through the 0.185 inch diameter CSK into
the 0.122 inch diameter hole at each end of the connector and fasten
with a suitable washer and nut. (Refer to Figure 3 below). Torque to
5.5 pound-inch maximum after soldering operation has been
completed.
If MB connectors are to be wave soldered to printed circuit
boards, the boards should be xtured to maintain assembly
straightness prior to and during the wave soldering process.
(Refer to Figure 4 below).
Alternate Mounting Variations for Mother Board Connector
A clinch nut (such as all ESNA 79NCFMA2-26 or equiva lent may be
pressed from the front, knurled end rst, through the 0.185 diameter
CSK into the 0.122 inch diameter hole at each end of the connector.
An appropriate length 2–56 UNC-3A screw, washer, and nut may be
used to mount the con nector. Mounting forces should be applied to
the bushing toward the rear of the connector. (See Figure 2 below)

DB connectors should be loosely held on the printed circuit board
prior to and during wave soldering. Care must be taken to ensure
that the board does not bow away from the center of the connector
during the soldering process. Also, especially on long length

PC CONNECTOR
The PC connector should be loosely attached to the printed circuit
board prior to any soldering of contacts.
Locking bushing accessory, two per connector, may be inserted from
the back of a PC connector body into large mounting holes at each
end. See photo at right. Part number to order locking bushing
accessory for PC connectors is 10-411196-4.The 0.126 inch
diameter cross holes in the locking bushing must be aligned with the
0.126 inch diameter cross hole in the PC connector body. These
holes accept a 4–40 UNC-2A screw which should be long enough to
allow mounting to the board. Fasten with a suitable washer and nut,
making sure an appropriate washer is also under the head.
The front of the locking bushing has a 4–40 UNC-2B thread which
will mate with the locking bushing accessory of an IO connector.
FIGURE 6: THREE TYPICAL MASKING APPLICATIONS FOR SOLDERING DB CONNECTORS
After soldering, mounting screws should be properly
torqued.
For cosmetic purposes, the board side of the DB
connector can be masked prior to wave soldering to
protect it from heat exposure and solder wash.
Acceptable masking may be accomplished with split
tubing, stainless steel, or Mystik Tape #7010 or #7367.
(Refer to Figure 6).
Printed wiring boards with DB connectors attached
should be inserted into the housing until rmly seated.
If possible, visual observation of the MB/DB mated
condition is recommended. The fully mated condition
occurs when the DB connector skirt bottoms on the MB
or PC connector shoulder along the full length. (Refer
to Figure 7).
Printed circuit boards should be supported in card
guides and locked in position when connectors are fully
mated.

The mounting surface to which the connector is applied
should not extend forward of the shoulder of the PC
connector. If the mounting surface does extend beyond
the shoulder, a shim (minimum 0.005 inch thick) must be
inserted between the connector body and the mounting
surface. (Refer to Figure 8). After soldering, mounting
screws should be properly torqued.
Fixturing of the PC connector and mounting surface may
be desirable to assure straightness after wave soldering.
INPUT/OUTPUT CONNECTOR
Use of mating hardware, such as locking screws, is recommended
with I/O connectors. See photo at right. Locking screw accessory, two
per connector, may be inserted into the large holes at each end of the
back of an IO connector body. Part number to order locking screw
accessory is 10-411196-4. By hand, press the locking screw rmly
down into the cavity until it reaches a positive stop. The locking screw
is then captivated in the retention system of the cavity. The front of
the locking screw has a 4-40 UNC-2A thread which will mate with the
locking bushing accessories of MB or PC connectors. (Refer to Figure
9 for I/O locking screw dimensions).
Should it be necessary to remove the captivated lock ing screw
accessory, push the screw as far forward as possi ble. Using vise grip
pliers to grasp the threaded end and pliers to hold the knurled end,
apply torque until the locking screw breaks in two. Each half will then
drop out.
Alternate Mounting Variation for Input/Output Connectors
For xed mounting, a 6-32 thread forming screw, type AB (MS5186)
may be inserted through the mounting member and into the holes at
each end of the connector body from the back. The screws must be
used with suitable washers and must be of sufcient length to
penetrate the connector body 0.350 inch. Care must be taken not to
over-tighten the screws.
FIGURE 8: PC CONNECTOR MOUNTING
FIGURE 9: I/O LOCKING SCREW DIMENSIONS
Visual observation of the mating of the MB connector to the I/O
connector or the PC connector to the I/O connector is recommend-
ed. The fully mated condition occurs when the I/O connector skirt
bottoms on the MB or PC shoulder along the full length. (Refer to

The B3 Brush contact is the standard contact for Low
mating force connectors due to its low mating force,
stable electrical performance and extended service
life. Design exibility is expanded with the ability to add
combinations of other types of contacts: signal, power,
high speed coax or ber optic termini; in one high
density hybrid connector.
Power, shielded coax or twinax contacts, in combina-
tion with Brush signal contacts are available in congu-
rations of the following (see next page for illustrations):
A single row of size 16 power or coax or twinax • contacts with 2 rows of brush contacts
A single row of size 12 power or coax or twinax • contacts with 3 rows of brush contacts
A double row of size 16 power or coax or twinax • contacts with 4 rows of brush contacts
Power and coax contacts are standard MIL-
DTL-38999 Series II type. Consult Amphenol board
level product marketing (800-678-0141) for assistance
with available hybrid congurations.
NOTE: Power and coax contacts and ber optic
termini are not provided with the connector and must
be purchased separately.

the same insert bodies as Amphenol low mating force
connectors, but have power contacts rather than brush
contacts. Cavities allow for size 16 or 12 power
contacts. Or, coax/twinax contacts can also be used in
these size 16 or 12 cavities.

HDB3 High Density Brush Series -
tighter (.070 in. X .060 in.) staggered grid spacing
HDB3 CONNECTORS
The new connector series of brush connectors incor-
porates an even higher density contact pattern and
lower mated height than Amphenol’s standard low mat-
ing force rectangular connectors. These HDB3 con-
nectors utilize the same durable and reliable B3 brush
contact, but in a tighter .070 inch X .060 inch staggered
grid spacing. They offer the advantage of a higher
density pattern in a compact-height connector that will
take up less board space; thus saving cost over adding
additional connectors to meet power requirements.
HDB3 connector styles include mother board, daughter
board, input/output and a stacker style.
For how to order information of the HDB3 see Amphe-

AMPHENOL CONTINUES TO DEVELOP
INTERCONNECTS THAT MEET THE DEMANDS OF
THE AVIONICS INDUSTRY
Starting with the development of the B3 contact, incorpo-
rated into the low mating force PCB connectors, the LRM
line replaceable module followed as the avionics high
density rectangular interconnect solution. LRM intercon-
nects are combinations of module and backplane inserts,
in one bay, two bay, three bay or more congurations.
LRM products are used on major programs of aircraft and
military vehicles.

age socket contact with inserts.
The RADSOK® design is a socket cylinder within the
female contact which has several equally spaced
longitudinal beams twisted into a hyperbolic shape. As
the male pin is inserted, axial members in the female
half deect, imparting high current ow across the
connection with minimal voltage loss. This twisted
hyperbolic grid ensures a large coaxial, face-to-face
surface area engagement.

HIGH SPEED LRM GIGASTAK AND DIGASTAK
INSERTS
More and more speed is needed in today’s interconnec-
tion products. Amphenol has recently developed a new
family of high speed LRM connectors that are capable of
achieving data rates in excess of 6.25 Gbps via 100 ohm
matched impedance differential pairs. Each insert
arrangement has been optimized through strategic place-
ment of signal and ground contacts for the perfect
balance of impedance control and cross talk mitigation
for a given data rate. As an enhancement over the
standard LRM, this new series offers a unique solderless
termination to module cards via Amphenol Intercon’s
cStack technology.
