FEATURES
1. The lowest profile class among two-
piece connectors in the world (Mated
height: 0.9mm)
Achieved both a 0.4 mm pitch and an
ultra low profile of 0.9 mm high when
mated, contributing to further thickness
reduction of products.
2. Strong resistance to adverse
environments! Utilizes
for high contact reliability.
1) Our own bellows-type double contact
structure provides a high resistance to
twisting and shock, ensuring a high
contact reliability.

Compliance with RoHS Directive
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.

2) Double contact construction makes it
highly resistant to foreign substances
such as dirt and flux.
3) Standard use of Ni barrier plating
The use of Ni barrier plating, which is
highly resistant against solder creeping,
on the socket terminals is standard.
4) Porosity treatment applied for
improved resistance against corrosion.
3. Improved mating strength between
the socket and header
The simple locking structures provided
for the retention fittings and the contact
points improve the mating strength and
provide tactile feedback when locked.
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. Easy to design product circuits
1) An insulating wall provided for the
bottom surface of the connector prevents
contact between the pattern on the PC
board and the metal pins, enabling
pattern wiring under the connector, and
thus contributing to the reduction in size
of PC boards.
2) The usage shown below further
enhances the flexibility of connector
positioning.

between a board and an FPC]
5. Connectors for inspection available
Connectors for inspection are available
that are ideal for modular unit inspection
and inspection in device assembly
processes.
APPLICATIONS
Compact portable devices “Cellular
phones, DVD, DSC, etc”
