3. Even with the low profile, the
effective mating length has been
extended to ensure that there is some
latitude in the mating.
With long effective
mating lengths, even
if the connection is
not perfect, the
electrical connection
is more than enough
for normal operations.
G
What is V notch construction?
By using the edge for the contacting part
and increasing contact pressure per unit
area, the effectiveness in removing flux
and contaminants is increased compared
to its predecessor. This is also effective in
preventing the trapping of contaminants.

3) Use of Ni barrier construction is
standard. Highly effective against solder
creeping.
(P5KS: Available from Nov. 2005)
G
What is Ni barrier construction?
By providing an exposed nickel part on the
gold (Au) plated contact, solder creeping is
prevented despite the ultra low profile.

5. Compliance with RoHS’ Directive
Environmentally friendly, the connectors’
comply with Europe’s RoHS’ Directive.
Cadmium, lead, mercury, hexavalent,
chromium, PBB and PBDE are not used.
APPLICATIONS
1. Mobile phones, PHS, mobile info-
communications terminals, and other
small portable devices
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.
Note: Construction makes solder creeping difficult
because header side is formed at the same time.
4) Porosity treatment applied for
improved resistance against corrosion.
What is porosity treatment?
This treatment consists of coating the
surface with a very thin film to seal pinholes
in the gold plating. This porosity treatment
technology ensures the same contact
reliability for thin gold plating as that of thick
gold plating.

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.
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: 1. Models with mating directionality to prevent reverse insertion have over 100 contacts. Models without mating directionality to prevent
reverse insertion have less than 100 contacts.
2. The plating on the solder terminal portion has changed from SnPb to Au plating from the production lot of December, 2002,
in order to eliminate lead.
3. Only “J” and “P” are supported as packaging specifications for models without Ni barrier. The packaging specification for Ni barrier
models is “G” only.
Models possible for “J” are as follows:
Sockets: Mated heights 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, and 6.5 mm
