■Features
1. Enhanced contact reliability and lock structure
The unique locking structure reinforces the
engagement between the wire side portion and
the header. This prevents the wire side from
becoming misaligned due to stress from poorly
routed wiring. (Fig.1) (Patented)
2. Vertical mating provides superior handling
The use of ver tical mating style reduces
assembly time and maximizes precious board
space which gives designers more freedom
when designing other components on the PCB.
(Fig.2)
3. Highly reliable contact structure
The two point contact structure provides optimum
reliability, a low mated height of 1.8mm and an
effective mating length of 0.35mm.
4. Increased cable retention
The header is designed to press the terminal
lance down during the mating operation; this
prevents the lance from moving and enhances
its strength.
And snap back in when
mating is complete.
A click feeling will be felt!

Vertical mating provides superior
operability and maximizes board space.
Vertical mating type
Side view of the PCB
Vertical mating style allows other parts to be mounted.
(Enhances freedom in designing PCB)
5. High current of MAX 4A (24 AWG)
By utilizing highly conductive material for the
female terminals and suppressing the contact
resistance, the DF65 series can handle a
maximum of 4A with 24 AWG wire.
6. Solder wicking prevention
Molding is done in a way that removes the gap
between the contacts and the housing to prevent
wicking.
7. Prevents Accidental unmating
The mating face is easy to see,
resulting in proper insertion.
Horizontal mating type
Unused, open area
The molded structure is designed to prevent
accidental unmating due to poorly routed wiring
and harsh loads.
8. UL and C-UL Certified
The mating face can be hard to see,
which can lead to awkward insertion.
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

Precautionary notes
1. Recommended Soldering
Profile
(Compatible with lead-free
soldering)
[Applicable Conditions]
1. Peak temperature : MAX 250ç
2. Heating Area : 220ç or above, within 60sec .

* Measurement is conducted at the contact lead part
Please check the mounting conditions before use, conditions such as
solder paste types, manufacturer, PCB size and any other soldering
materials may alter the performance of such materials.
(Note 1) This temperature profile is a recommended value only ; please
contact your Hirose Sales Rep for more information
2. R e c o m m e n d e d h a n d
soldering conditions
Temperature of soldering iron : 350±10ç, soldering time : no more than 3
seconds
3. R e c o m m e n d e d s c r e e n
thickness, aperture ratio
(pattern surface ratio)
Thickness : 0.1mm, aperture opening ratio : 100%
4. Warping of PC Board
A maximum of 0.02mm at the center of connector, as measured from either
end of the connector
5. Cleaning Conditions
IPA cleaning is allowed. (Cleaning is not recommended because
cleaning may change the push/pull feeling etc. Please contact your local
Hirose representative prior to the use of any cleaning agents.)
6. Precautions
■ When inserting the crimp contact into the crimp socket, do not insert it at a
slanted angle to maintain the reliability of its performance.
■ Please use caution when mating/unmating this connector if it has not been
mounted onto the PCB, doing so could deform or damage the contacts.
■ Do not pull on the wires of this connector as this may cause damage to the
connector.
■ During the hand soldering process, make sure to not apply too much flux.
Doing so may cause a solder wicking problem.
■ This product may experience some differences in color from one production
lot to another. This color difference does not influence the performance of
the connector.
■ For handling precautions to be used during the insertion/removal process,
please refer to the “DF65 Push-pull procedure” (ETAD-H0803).
■ For the assembly procedure and the instruction manual, please refer to the
“DF65 Cable Assembly Procedure” (ETAD-H0736).
