The NANO Line - .025" Contact Spacing
NANO contacts incorporate the highly reliable Twist
Pin concept, which allows continuity in very dense
areas and under severe shock and vibration, requir-
ing low engagement and separation forces. Termi-
nation can consist of uninsulated pigtails or in-
sulated wire all pre-harnessed at our factory to your
specifications.
Due to various industry application requirements,
the NANO line is available in several different
configurations: strip, metal shell and plastic, rec-
tangular or circular configurations with center jack-
screw, a 72 position circular connector with center-
jackscrew, metal shell with combination layout, or
discrete board-to-board stacking contact.
Successful applications for NANO connectors are
many and varied, from the Air Force's AIRS program
to actual human implantations in the medical re-
search field.
