■Features
High contact reliability - effective mating length 0.45mm
1. High density mounting
H]dX`VWhdgei^dcg^Wh
In addition to its space saving design, several stack
heights are available and add versatility to any
application. Stack heights : 1.5mm, 2.0mm, 2.5mm,
3.0mm, 3.5mm, and 4.0mm.
%#)*bb
2. Multiple stack height options
&#*∼)#%bb
Space saving design that has a minimum connector
width, yet still retains a sufficient vacuum area for
easy pick-and-place mounting
Minimum width : 3.38mm
3. High contact reliability
4. Excellent self-aligning range
The use of guide ribs allows 0.33mm of selfalignment on this connector.
5. Reinforced structure with shock absorbing ribs
Both sides of the connector have been reinforced
with the addition of shock absorbing ribs.
6. Solder wicking prevention
Nickel-plated barriers were added to protect the
contact areas from potential solder wicking.
7. Contamination resistant design
When mated, the connector’s design covers the
contacts which help to keep dust and other debris away
from the contacts. The SMT leads are kept very close
to the connector housing which also helps to prevent
shorts caused by debris on the exposed contacts.
8. RoHS compliant
Environment friendly and does not use RoHS
specified prohibited materials.
All materials and substances used to produce these
parts comply with the RoHS standards.
9. High speed signal with noise prevention

No. of Contacts
Despite its small stature and low profile, the contacts
deliver strong contact forces and an effective mating
length of 0.45mm on the 1.5mm stacking height.
This connector utilizes a locking system that prevents
accidental unmating issues and emits a clear tactile
click to ensure that mating has been completed.

5. Washing
Cleaning/washing is not recommended for this connector. Cleaning agents can
deteriorate the mechanical operation and the environmental resistance of this
connector.
6. Precautions
■ Do not mate or unmate these connectors until they are mounted, failure to follow
this precaution can lead to deformation or damage to these connectors.
■ Provide another form of support to the PCB, this connector was not designed to
be the main form of support.
■ Mating and unmating with excessive force can cause damage.
■ Do not apply excessive amounts of flux as it may cause excess solder and flux
wicking.
■ There may be a slight variance in the color of the molding between production
lots, this variance will not affect the performance of the connector.
■ Refer to the next page for the handling precautions when mating and unmating
the connectors.
■ If the connector becomes disconnected due to impact, a fall or a counterforce to
the FPC, it may be necessary to hold the connector in place with an addition to
the device’s case or other cushioning material to hold the connector in place.

Prior to mating, locate the guidance ribs and
align the header.
Do not apply excess force to the connector
during mating. Doing so can lead to contact
damage.
Make sure that the connector is parallel to
the other side, it then will drop down slightly.
Continue to press it down until it is fully mated
while maintaining the angle. Do not apply
excessive force as it may damage the contacts.

To unmate this connector, lift evenly across
the header, making sure that each side stays
parallel to each other.
If circumstances prevent the connectors from
staying parallel to each other, then one side
may be lifted as shown in the diagram. This
method is only approved if the connector is
mounted onto an extremely rigid circuit board.
If the board were to warp during this process
it may result in damage to the connector or its
solder joints.
Pitch direction
Corner direction
Do not try to disconnect these connectors by
pulling on one side or a corner, or unmate it
while it is securely mounted onto a rigid FPC.
These actions may lead to deformities and
ultimately a damaged connector.
As shown in the figure to the left, do not unmate
it from the width direction (front to back), it may
damage contacts.

The contact may peel away if there is
not enough rigidity in FPC.
Receptacle
FPC
When mounting the receptacle side to FPC
which does not have enough rigidity, the contact
may peel away soldered connection.

Header
We recommended to mount the header side to
the FPC.
Header
FPC
We have conducted evaluations on the
requirements needed for FPC rigidity. If you
need to mount the receptacle to the FPC,
contact your local Hirose Rep for this data.
Receptacle
Even when mounting the header side to FPC,
if the rigidity of FPC is low, the connector may
break as shown in the left figure. Please check
the strength and durability of FPC before using.
For the evaluation results of each item and FPC
rigidity, please contact us.
