Amphenol® Bristle Brush Contact:
Multiple Strands of High Tensile Strength
Wires Bundled Together, Providing Superior
Electrical Connection with Low Mating Force
Amphenol’s Broad Family
of Low Mating Force
Interconnect Products
with Brush Contacts
The Bristle Brush contact has been
proven in military avionics pack-
ages and meets the requirements
of MIL-DTL-55302. It provides high
density in tighter spacing, low mat-
ing/unmating forces, proven durabil-
ity and long contact life. Applications
for Amphenol® Connectors with
Brush contacts include:
• Medical equipment
• IC chip testers
• Telecommunications
• Military and Commercial Aviation
• Military Ground Vehicles
• GPS systems

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.
