FEATURES
1. 0.4 mm pitch and support for mated
heights of up to 1.5 mm, 2.0 mm, 2.5
mm, 3.0 mm, 3.5 mm, and 4.0 mm.
2. Strong resistance to adverse
environments! Utilizes
for high contact reliability.
1) Contacts are highly resistant to shock
caused by dropping and employ our
original bellows contact construction.
2) V notch construction used for excellent
resistance against foreign matters.

Compliance with RoHS Directive
● V-notch
By making contact with the edges and thus
increasing the contact pressure, this pro-
duct can eliminate flux and other foreign
matters more effectively than conventional
products, which also helps to prevent for-
eign matters from obstructing the contact.

<Product without a notch>
Contacts are formed by
bending a thin metal sheet,
which provides the contact
parts with adequate spring
characteristics ensuring
greater resistance to prying
forces and drop impacts.

3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping.
4) Porosity treatment applied for
improved resistance against corrosion.
3. It is constructed with impact
dispersion keys inside the body to
disperse shocks when dropped.
A high level of shock resistance is
ensured by dispersing impact over the
four locations where the socket
indentations and header protrusions are
mated together.

FOR BOARD-TO-BOARD AND
Porosity treatment
This treatment consists in coating the sur-
face with a very thin film to seal pinholes in
the gold plating. We have developed this
porosity treatment technology, which en-
sures contact reliability for thin gold plating
comparable to that of thick gold plating.
● Improvement in insertion/removal durability
● Improvement in resistance to corrosion
● Improvement in contact reliability for digital signals
● Ni barrier
The exposed nickel-plated portion of the
gold-plated contact prevents solder creep
despite the ultra low profile of the contact.

4. Construction makes designing
devices easier.
1) The lower connector bottom surface
construction prevents contact and shorts
between the PCB and metal terminals.
This enables freedom in pattern wiring,
helping to make PCB’s smaller.
2) Guides are provided to take up any
position shift and facilitate insertion.
3) The connector has a simple lock
mechanism.
Superior mated operation with click feel
to indicate that mated is complete.
5. Design makes efficient mounting.
Features a terminal flatness of 0.08 mm,
construction resistant to creeping flux,
and design that facilitates visual
inspection of the soldered part.
6. Connectors for inspection available
Connectors for inspection are available
that are ideal for modular unit inspection
and inspection in device assembly
processes.
