FEATURES
1. Space-saving (3.6 mm widthwise)
The required space is smaller than our
F4 series (40-contact type):
The small size contributes to the
miniaturization of target equipment.
* Clips for preventing the solder joints from being removed
2. Highly reliable
resistance to adverse environments.
1) Our original bellows contact: High
resistance to drop impact and twisting
forces.
Note: If extra resistance to shock caused by dropping

Contacts are formed by
bending a thin metal sheet.
This provides the contact
parts with adequate spring
characteristics ensuring
greater resistance to twisting
forces and drop impacts.

2) V-notch + double contact:
High resistance to the penetration of
foreign matters and flux.
3) Ni barrier: High resistance to solder
creep.
4) Porosity treatment: Resistance to
corrosion.
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.
● Improved in insertion/removal durability
● Improved in resistance to corrosion
● Improved in contact reliability for digital signals
● 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.

● Ni barrier
The exposed nickel-plated portion of the
gold-plated contact prevents solder creep
despite the ultra low profile of the contact.

3. The simple lock structure gives
tactile feedback that ensures a
superior mating/unmating operation
feel.
4. Gull-wing type terminals
The gull-wing type terminals facilitate
automatic mounting inspections.
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, DVC, Digital cameras, etc”
