17 TW SERIES
Amphenol’s 17TW series hybrid
D-Subminiature connectors are
available with power, coax, high
voltage and signal contacts
assembled in the same connector
body. These connectors are
supplied with screw-machined
contacts which are xed in the
insulator.
The board-mount product
offering includes straight and
right-angle terminations. The
cable connectors are available in
crimp and solder terminations.
These connectors are compatible
with the infra-red reow
soldering process. The 17TW
series offers eighteen housing
congurations in ve shell sizes.
