Product Specification
108-2202
The trends in electronic
power supplies require high
current density and lower
cost. In addition, smaller
sized connectors are
needed to provide less
airflow restriction for cooling
the power supplies. The
SEC-II Power connectors
offer an ideal combination
of low-current and high-
current connections in a
single, durable design.
SEC-II Power connectors
are built on an expandable
tooling platform which
allows for a variety of
combinations of power
and signal contacts, all
combined in a single
molded housing. The vertical
press-fit versions are ideal
for high density stacking
of cards into a backplane
or for low air restriction of
blade-style power supply
designs. The straddle
mount style offers a true
co-planar interconnection
with a total height of less
than 4mm from the top
surface of the pcb.
SEC-II Power Connectors
are currently in use in
high-end computer and
data storage equipment.
Extensive testing in expo-
sure to high vibration and
shock has proven these
connectors equally suited
for industrial applications as
well, where low contact
resistance and high current
density is required.
