3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping.
G
What is Ni barrier construction?
By providing an exposed nickel part on the
gold (Au) plated contact, solder creeping is
prevented despite the ultra low profile.

• Without retention fitting: 18 contacts or
less
• With retention fitting: 22 contacts or less
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.

Note: Construction makes solder creeping difficult

4) Porosity treatment applied for
improved resistance against corrosion.

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
construction
for high contact reliability.
1) Contacts are highly resistant to shock
caused by dropping and employ our
original bellows contact construction.
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.
This treatment consists of coating the
surface with a very thin film to seal pinholes
in the gold plating. This porosity treatment
technology ensures the same contact
reliability for thin gold plating as that of thick
gold plating.

mechanism.

to indicate that mated is complete.

2) V notch construction used for excellent
resistance against foreign matters.
G
What is V notch construction?
By using the edge for the contacting part
and increasing contact pressure per unit
area, the effectiveness in removing flux
and contaminants is increased compared
to its predecessor. This is also effective in
preventing the trapping of contaminants.

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.
Note: The following numbers of contacts are not
supported due to suction surface factors.
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. Compliance with RoHS Directive
Environmentally friendly, the connectors
comply with Europe’s RoHS Directive.
Cadmium, lead, mercury, hexavalent
chromium, PBB and PBDE are not used.
7. Connectors for inspection available
Connectors for inspection are available
that are ideal for modular unit inspection
and inspection in device assembly
processes.
