environments! Utilizes
for high contact reliability.
1) Contacts are highly resistant to shock
caused by dropping and employ our
original bellows contact construction.

• What is meant by “bellows type” contact?
Rather than two broken-out surfaces, the contact is
formed by the surfaces of two rolled plates. This
helps the contact hold up better to repeated
insertions and removals, while at the same time
achieving highly reliable contact.
The roll surfaces
are in contact
with each other,
providing high
contact reliability.

The external
appearance and
PC board pattern
differs for the P5K
and P5KS series.
Since the contact is
formed by bending
thin plate, it has a
spring-like quality.
This construction
helps make it resist-
ant to dropping and
twisting.

Notes
P5KS
2) V notch construction used for excellent
resistance against foreign matters.
(P5KS: Available from Nov. 2005)
3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping.
4) Porosity treatment applied for
improved resistance against 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.
● 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.

Socket side contact
● 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.

Effective mating length
3. Even with the low profile, the
effective mating length has been
extended to ensure that there is some
latitude in the mating.

APPLICATIONS
1. Compact portable devices “Cellular
phones, DVC, Digital cameras, etc”
2. The 160-contacts connector:
This connector is particularly suited to
the motherboard, CPU board, and other
multi-pin expansion boards on notebook
PCs and other info-communications
applications.
