the B3 Contact Innovation . .
The Amphenol® B3 Contact is an engineered, inno-
vativ e soluti on to prob le ms ca used by the high mat-
ing and unmating forces of conventional pin and
socket contact pairs. B3 stands for Bristle Brush
Bunch, a descriptive name for the multiple strands
of high tensile strength wire that are bundled
together to form the brush-like contact. By inter-
meshing two multi-strand wire bundles, an electrical
connection is made. The B3 contact design results
in low, normal contact site forces and significantly
reduces mating and unmating forces.
The B3 Contact offers:
• low mat ing/un mat in g forces
• superior electrical characteristics
• proven durability and long contact life
• a n ew age of PC design
Applications for Amphenol Connectors with Brush
B3 contacts:
• Medical equipment
• IC chip testers
• Telecommunications
• Military and commercial aviation
• Military ground vehicles
• GPS systems
•Space
• Industrial

with Brush signal contacts in one high
density (hybrid) connector.
• Available with 100 brush signal contacts
with up to 12 size 16 power or coax con-
tacts in a 2 row connector
• Available with 180 brush signal contacts
with up to 12 size 12 power or coax con-
tacts in a 3 row connector
• Use of standard MIL-DTL-38999*, Series
II power and coax contacts
Hybrid configurations can be made available
with fiber optics and Brush contacts in the
same connector.
Amphenol’s superiority and breadth of product offer-
ing is demonstrated in its capability for packaging
fiber termini and the Brush contact in a printed circuit
board rectangular connector. Optical performance,
high speed and secure communication are obtained
with fiber optic interconnects incorporated into the
rectangular housings, along with the low mating force
advantages of the brush contact in the same connec-
tor.
NOTE: Power and coax contacts and fiber optic termini are not
provided with the connector and must be purchased
separately.
Consult Amphenol Aerospace, Sidney, NY for assis-
tance in solving design problems and for part num-
bers that will provide the proper combination of these
hybrid configurations to meet your specific connector
application requirements.

CONTACT REMOVAL - DB SERIES
Contact removal is accomplished from the front or mating
si de of this connec t o r ser ie s w i thout re m ov ing t h e e ntir e c on -
nector from the printed circuit board. Determine which con-
tact is to be removed from the connector and cut tail.
Unsolder cut tail. Solder sucking may be necessary to clear
the printed ci rcuit board of solder and cut tail.
Pull the contact through the front side of the connector with
tweezers. Care must be taken not to damage adjacent con-
tacts. Discard the damaged contact.
CONTACT REPLACEMENT/INSERTION - DB SERIES
Using tweezers or fingers, carefully place the replacement
contact TAIL FIRST into the appropriate contact cavity in the
front of the connector. Before final seating of the contact
mak e pr o vi si on s for pr op er dr e ss in g of t h e c o nta ct, s in c e t he
90° tail of the DB connector must be routed through its nest in
the c onn ecto r bod y mold ing a nd, in tu rn, in to th e prin ted cir-
cuit board hole.
Push the con tact into the cav ity wi th a flat- edged rod of .0 60
to .100 inch diameter until contact seats. Do not push against
bristle wires or bend shroud. It may be necessary to simulta-
neously bend the contact tail during this step. Dress and
resolder contact tail in proper location.
CONTACT REMOVAL - MB, PC SERIES**
Contact removal is accomplished from the front or mating
side of these connector series without removing the entire
connector from the printed circuit board. Determine which
contact is to be removed from the connector and unsolder or
unw rap the cont act t ail as a pplic abl e. T ail c uttin g and/o r sol -
der sucking may be necessary to clear the printed circuit
board.
Inspect the damaged contact to determine if the bristle wires
are bent in a particular direction within the contact cavity. The
slot in the tube end of the 11-10368 Extraction Tool is
designed to acc o mm o da t e th es e bent stran ds .
Ret r ac t th e plunge r of the 11 - 1 03 68 Ext ra c t io n To ol to its fu r-
th est po int o f tra vel, and l ine up th e slo t in th e tu be e nd w ith
any bent bristle wires in the contact cavity. Insert the tool into
contact cavity. A moderate amount of resistance will be
encountered until the contact retention tines are deflected,
and t he n a po si tive stop wil l be fe lt .

each end of the connector. An appropriate length 2–56 UNC-
3A screw, washer, and nut may be used to mount the connec-
tor. Mounting forces should be applied to the bushing toward
the rear of the connector.
2. 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 en d of the c onne ct or and fa st en wi th a sui table was her

test probe kit
In order to insure that contacts are properly wired
within a connector, a Test probe Kit (11-10400-22)*
is needed. This kit is especially 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 assembly.
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 wi re 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
than .062 for MB-PC and not more than .038 for
DB/IO.
AWG 22242628
SEL 5432
Insert stripped wire end into contact wire well.
Strands should be visible in wire well inspection
hole. Bottom contact and wire assembly in posi-
tioner, and close handles of crimp tool to complete
crimp. Handles will not open unless full crimping
cycle has been completed.
