Product Data Sheet
Amphenol® HDB3 Series High Density
Mother Board & Daughter Board Connectors
No. 201-3
Rectangular Interconnects with
.070” X .060” Grid Spacing
HDB 3 Mother Board
Connector
This new connector series incorporates a higher
density contact pattern and lower mated height
than Amphenol’s original Low Mating Force rectan-
gular connectors while utilizing the same durable
and reliable B3 contact.
The B3 brush (bristle brush bunch) contact is
comprised of multiple strands of high tensile wire
that intermesh to create an electrical connection.
