NARROW-PITCH
CONNECTORS FOR
BOARD-TO-BOARD
AND BOARD-TO-FPC
CONNECTION
NARROW PITCH
(0.4mm) CONNECTORS
P4 SERIES
FEATURES
1. 0.4 mm pitch and support for mated
heights of up to 1.5 mm, 2.0 mm, 2.5
mm, 3.0 mm, 3.5 mm, and 4.0 mm.
2. High impact-resistant construction.
1) Adoption of bellows-type contact
structure.
2) Guides are provided to take up any
position shift and facilitate insertion.

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 resistant to
dropping and twisting.
3) The connector has a simple lock
mechanism.
2) It is constructed with impact dispersion
keys inside the body to disperse shocks
when dropped.
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.

Note: Construction makes solder creeping difficult
because header side is formed at the same time.
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.

A high level of shock resistance is
ensured by dispersing impact over the
four locations where the socket
indentations and header protrusions are
mated together.
Note: The following numbers of contacts
are not supported due to suction surface
factors.
• No retention fitting: 18 contacts or less
• With retention fitting: 22 contacts or less
3. Construction makes designing
devices easier.
1) 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.
4. Design makes efficient mounting.
Features a terminal flatness of 0.08 mm,
construction resistant to creeping flux,
and design that facilitates visual
inspection of the soldered part.
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.
6. Connectors for inspection available
Connectors for inspection are available
that are ideal for modular unit inspection
and inspection in device assembly
processes.
APPLICATIONS

phones, DVC, Digital cameras, etc”
Ideal for Board-to-FPC connections

The simple lock mechanism
ensures that the connector
clicks into position when it is
inserted for reliable singleaction 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.
