AXK(3/4)S
NARROW-PITCH
CONNECTORS FOR
BOARD-TO-BOARD
CONNECTION
FEATURES
1. Bellows-type contacts
Bellows-type contacts resist mating stress
and offer high contact reliability.
Socket and header are mated
Round corner
makes contact.
The bellows type
contacts are fabricated
by bending thin sheet
metal. They offer reliable
contact since a rounded
corner, instead of a
sharp edge, is used for
tuning fork type contact.
NARROW PITCH
(0.6 mm) CONNECTORS
P6 SERIES — P6S —
APPLICATIONS
1. Small portable equipment, personal
computers, word processors, video
equipment, radio communication
equipment
2. This is ideal in applications involving
information devices such as notebook
computers, where connections are
required between a backplane and a
CPU board or another type of multi-
wiring expansion board.
Socket
2. Mating length 1.1mm
The effective mating length has been
extended to ensure that there is some
latitude in the mating.
A longer effective mating
length means that normal
electrical connection can
be maintained even if the
connectors are not
perfectly coupled.

Notes) 1. Please add following suffix at * marked positions.
J: Inner carton (1 reel) 1,500 pcs. (Outer carton: 3,000 pcs.)
P: Inner carton (1 reel) 1,000 pcs. (Outer carton: 2,000 pcs.)
As for the part No. P is suffixed, only 1,000 pcs. reel is available.
2. Regarding ordering units: During production: Please make orders in 1 reel units.
Samples for mounting confirmation: Please consult us. (See “Regarding sample orders to confirm proper mounting” on page 9.)
Samples: Small lot orders are possible. Change the suffix “J” to the suffix “P,” or place a “P” where the “*” is located.
3. The standard type comes with no positioning bosses. Connectors with positioning bosses are available for on-demand production.
For this type of connector, 9th digit of the part no. changes from 3 to 4 e.g. AXK3S20045P.
