After mating
1.Reinforced lock structure with swing lock
A swing-lock structure, featuring our own unique
connection method, reinforces the lock structure of
the electric cable side, with a structure resistant to
tough electric cable routing and disengagement of
cables under load.
In addition, the connection surface has a guide
insertion to facilitate insertability (patented)
2.Header lock improves plug retention
When connecting, the header connector secures the
molded-lance. Play of molded lance is prevented for
added strength. (patented)

3.Highly reliable contact structure
Despite the low-profile design, with a stacking height
of 1.4mm, an effective mating length of 0.42mm is
achieved. The structure features two-point contact
terminal geometry with high contact reliability.
4.Insert guide key prevents misalignment
Insert guide key guides the crimp socket to the
correct mating position and prevents misalignment,
which improves mating operation and prevents
possible connector breakage with incorrect mating.

Incorrect Positioning
Insert Guide Key
The integral molding eliminates any gap between the
terminals and case to prevent solder wicking.
Reinforcing hardware (metal fittings) are integrated in
the molding, which help prevent the case from
disengaging with the terminals due to tough electric
cable routing and load.
Positive Lock
Insert guide key touches to
the header prior to the
positive lock, which guides
the socket to the correct
mating position.

Starts mating after the socket is aligned to
the correct position
7.Cost effective
Terminals and metal fittings are collectively integrated
into the molding to reduce assembly cost.

In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.

into multiple circuits, current ratings may go above the stated current ratings. Please consult Hirose for specific details
before doing this.
Note 2 : Includes the temperature rise of power lines.
Note 3 : The connector should be completely dry. (no condensation present)
Note 4 : The term “storage” refers to the long-term storage condition of unused products before PCB mounting. The operating
temperature and humidity ranges are applied while in a non-energized state, while in transport or after PCB mounting.

6.Precautions
Maximum of 0.02mm at the connector center, with both ends of the connector as reference points.
Cleaning is not recommended. When cleaning, please evaluate as if can deteriorate the
performance including mechanical operation and environmental resistance.
■When inserting crimp-type (solderless) terminals to crimping (solderless) sockets, to maintain
reliable performance, please do not insert obliquely.
■DO NOT mate/un-mate non-terminated plugs with non-mounted receptacles.
This may lead to damage or deformation of the contacts.
■Removal of the holding electric cable may cause damage so please be careful.
■DO NOT apply flux to the contact terminals when hand soldering the receptacle to the board.
Wicking of the flux into the electrical contact areas may lead to connection failures.
■Slight discoloration on the insulating materials will not affect form, fit or function of the
connectors.
■Please refer to the documents "DF57 Series Cable assembly Procedure ETAD-H0421", "Crimp
condition" and "DF57-****SCF(A)(**) Crimp quality standards ATAD-H0404" for the cable
assembly procedures.
■Please refer to the "DF57H Series Mating/Unmating Operation Instruction Manual (ETAD-H0652)"
for the connector operation.
