Cleaning
Cleaning is not recommended.
If you clean this product, please evaluate its performance before using it.
(Cleaning may impair the mating/unmating properties and lower resistance to environmental factors.)
Precautions
・Be careful when mating/unmating the connector when it is not mounted on the
PCB as it may cause damage/deformation to contacts.
・Avoid supporting the PCB only with the connectors.
Support it by other means such as bolts, screws, posts, etc.
・Excessive prying during unmating/mating may result in damage.
・In the case of hand soldering, please do not apply any flux which could cause flux wicking.
・This product may have slight color differences due to production lot variability,
but this does not affect the performance.
・Please refer to the following page for handling precautions when inserting and removing.
・Because the product can disengage if dropped
(or other impact), or by FPC routing, it is advised to secure the mated connectors to
the board with housings and cushioning materials.
・Do not use the connector in non-recommended conditions
(i.e., rated current, rated voltage, PCB design and operating environment, etc.).
Such usage could lead to material outgassing, ignition, or short-circuit, etc.
Refer to the specifications and guidelines for board pattern dimensions,
board cautions, and connector treatment.
Please contact Hirose if connector usage in conditions other than those described in the
specifications and the guidelines is being considered.

Precautions for Handling During Use
【 Mating Method of Connector】
When Mating this Item, please do so by hand.
Mating Method
1．Locate the guide port and align. This product has a guide rib on the plug to ensure proper engagement.
Once aligned, the connector engages. You can feel the mated height of the connector lower.
Move the connector forward and backward, left and right to find the guide port.
Apr.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
Finding
Mated height goes down one step.
Finding
2. In the engaged state, the connectors are parallel to each other, and the connectors cannot move forward,
backward, left, or right. Complete mating from this state.
3. Check that mating is completed.
If one side is floating, or if it is mated at a diagonal, remove and re- mate.
【 Handling Precautions for Connector Removal】
1. When removing the connector, it is preferable to pull it out in the upward direction from the connector
mounting surface.
However, when removing the FPC from the circuit board it becomes more difficult to remove it vertically
with higher pin counts and thin FPCs.

ＯＫ

2. If difficult to remove, extract the connector diagonally in the direction of the pitch.
Note that removal from the widthwise side will apply a large load to the contacts.

3. If the FPC does not have sufficient rigidity, solder stripping or connector breakage may occur.
Please use it after checking the repetitive operation with a flexible board in advance, such as during a trial
manufacture run.
Refrain from holding the corner of the flexible board and removing it diagonally as it will result in a large
load to the contacts.

While Taking into Consideration
Specifications mentioned in this catalog are reference values.
When considering to order or use this product, please review the Drawing and Product Specifications sheets.
Use an appropriate cable when using the connector in combination with cables.
If considering usage of a non- specified cable, please contact your sales representative.
If assembly process is done by jigs & tools which are not identified by Hirose, the warranty of the product may be
affected.
If considering usage for below mentioned applications, please contact your sales representative.
In cases where the application will demand a high level of reliability, such as automotive, medical instruments, public
infrastructure, aerospace/ defense etc. Hirose must review before assurance of reliability can be given.

DF40F Series/Small Floating Board-to-Board Connector, 125ºC Heat Resistance for Automotive
Applications
It can be used for in- vehicle applications for front cameras, Rear/ Side Cameras, Millimeter- Wave Radar LiDAR and other
devices that require misalignment absorption of the substrate by small size floating. It can also be used in devices that
require absorption of the substrate misalignment for consumer and industrial equipment.

Cleaning
Cleaning is not recommended.
If you clean this product, please evaluate its performance before using it.
(Cleaning may impair the mating/unmating properties and lower resistance to environmental factors.)
Precautions
・Be careful when mating/unmating the connector when it is not mounted on the
PCB as it may cause damage/deformation to contacts.
・Avoid supporting the PCB only with the connectors.
Support it by other means such as bolts, screws, posts, etc.
・Excessive prying during unmating/mating may result in damage.
・In the case of hand soldering, please do not apply any flux which could cause flux wicking.
・This product may have slight color differences due to production lot variability,
but this does not affect the performance.
・Please refer to the following page for handling precautions when inserting and removing.
・Because the product can disengage if dropped
(or other impact), or by FPC routing, it is advised to secure the mated connectors to
the board with housings and cushioning materials.
・Do not use the connector in non-recommended conditions
(i.e., rated current, rated voltage, PCB design and operating environment, etc.).
Such usage could lead to material outgassing, ignition, or short-circuit, etc.
Refer to the specifications and guidelines for board pattern dimensions,
board cautions, and connector treatment.
Please contact Hirose if connector usage in conditions other than those described in the
specifications and the guidelines is being considered.

● Securing PCBs
This connector can absorb misalignment between PCBs, but not vibration.
If you support PCBs only with the connectors without taking any fixing measures, the load on the connectors will be
excessive and may cause broken or contact failure.
Be sure to secure PCBs except for the connectors as shown below to prevent the board from moving. This connector
connects the board to the board.
When using mounting to FPC, fasten the board and FPC to the case separately.
Fixing PCBs with a Spacer or Case
OK
Do not use the product without fixing PCBs together.
18
DF40F Series/Small Floating Board-to-Board Connector, 125ºC Heat Resistance for Automotive
● Mating Precautions
1. Mating
The alignment dimension is ±0. 3mm in the X and Y directions.
After the start of mating, follow the alignment and mate perpendicularly to the board without applying an overloading to
the connector.
Apr.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
±0.3mm
±0.3mm
2. Misalignment Allowance in Mated Condition ( Floating Range)
Because of floating design, this connector has a ±0. 3mm board misalignment tolerance in the X and Y directions when
mated. However, it is not suitable for absorption when the range of misalignment constantly changes due to vibration,
etc. The number of repetitions of floating movable operations is stipulated to be no more than 10 times.
±0.3mm
±0.3mm
3. Removing
When removing the connector, pull it out in parallel.
If it is removed in an inclined position, connector may deform.
