The Centi Line - .075" Contact Spacing
ITT Cannon Centi connectors are especially suitable
for commercial applications such as computers,
instrumentation, model airplane R/C equipment,
calculators, communications and audio equipment.
They are available in D subminiature size metal
shell rectangular, plastic shell rectangular and strip
configurations.
All Centi connectors use the reliable twist pin
cotact design in a 5 amp version terminated on
.075 (1.91) and .100 (2.54) centers. This larger
contact is crimp removable, so Centi Series connec-
tors are available in connector kits and as bulk parts
for customer assembly. Standard crimp and as-
sembly tools are available.
The twist pin contact is recessed within the in-
sulator housing while the rugged cylindrical socket
is exposed. When the connector halves are mated,
the chamfered sockets guide the pins into positive
alignment. The Centipin™ contact, now under com-
pression, forms a multi-point contact with the
Centisocket™ to provide a high degree of reliability.
