FEATURES
1. The connector is a two-piece
structure and 0.5mm pitch.
The product lineup consists of the mated
height of 1.5mm, 2.0mm and 2.5mm.
2. Strong resistance to adverse
environments! Utilizes
for high contact reliability.
1) The socket and header has the same
dropping shock and torsion resistant
construction as the bellows-type contact.
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.

Socket
Since the contact is formed
by bending thin plate, it
has a spring-like quality.
This construction helps
make it resistant to
dropping and twisting.

construction
3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping. (Available from Oct. 2005)
4) Porosity treatment applied for
improved resistance against corrosion.
3. Simple locking structure
Superior mating operation with click
feel to indicate that mating is
complete.
4. Mating length 0.55mm
While achieving a low profile of 1.5mm
between PCBs, the effective mating
length has been extended to ensure that
there is some latitude in the mating.
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.

5. 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.
6. Automatic mounting inspection is
facilitated by the gull-wing terminal
shape which makes mounting
verification easy.
7. 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, DVC, Digital cameras, etc”
Ideal for Board-to-FPC connections

Connector bottom: Create any thru-hole and pattern wiring.
The simple lock
mechanism ensures
that the connector
clicks into position
when it is inserted for
reliable single-action
insertion on the PCB.

This enables the number of pins to
be doubled white the size remains
the same as that for existing FPC
connectors. This, in turn, contributes
to making products and equipment
more compact.
