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. Ultra low profile, but high contact
reliability
Our own bellows-type double contact
structure provides a high resistance to
twisting and shock, ensuring a high
contact reliability.
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.
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. 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.
