Other Brush Contact Rectangular Connectors
HDB
tighter (.070 in. X .060 in.) staggered grid spacing
HDB
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 HDB
nectors utilize the same durable and reliable B
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.
HDB
board, input/output and a stacker style.
