Features
1.
Highly reliable connection and robust structure
Multi-polarized connectors, reinforced body structure and
high FPC retention produced by the following features:
Reliable connection created by its unique FPC/FFC
positioning mechanism
Prevents accidental disengagement with the design of its
proprietary structure
2. Simplified operations
The flip lock structure makes it easier to engage/disengage
the actuator and reduces the required force needed to
operate. A clear tactile click is delivered upon the
successful completion of the mating process. (Fig.1)
3. Increased FPC/FFC retention force
Vertical retention force for the FPC/FFC is 2.5 times
stronger than our 0.5mm pitch connector the FH12 series.
Horizontal retention force for the FPC/FFC is 2 times
stronger than our 0.5mm pitch connector the FH12 series
*To realize the horizontal retention force values, the use
of the FPC positioning tabs are required. FPC without
the positioning tabs will comply with the specifications
rated on the FH12 series.
4. Accepts standard 0.3mm thick FPC/FFC
It accepts 0.3mm thick products that are easy to
manufacture and have superb insertion performance.
5. Fully molded structure aids PCB layout
The bottom of this connector is enclosed by a fully
molded structure that protects the contacts and
removes any restrictions from PCB patterning and
design.
6.
Supports automatic pick-n-place mounting
Offered in tape and reel packaging that is compatible with
automatic machine mounting. (2,000pcs/reel)
7. Halogen-free
All materials and substances used to produce this product
comply with Halogen-free standards.*Defined according
to IEC61249-2-21. Br : 900ppm maximum, Cl : 900ppm
maximum, Br+Cl : 1,500ppm maximum
8. Multiple packing options
The standard packaging is 2,000pcs/reel, but it is
also offered in a 500pcs/reel. (The outer diameter of
the reel will be Ø330mm in this case.)
0.5mm and 1mm Pitch, 2.55mm Height FPC/FFC Connectors
FH28 Series
1
Robust locking structure
Reinforced fitting provide support and prevent
the actuator from disengaging from the connector.
Each terminal is attached to the actuator,
so the actuator is supported along its entire length.
The FPC positioning mechanism and FPC tabs help to
guide and hold the FPC prior to engaging the actuator
Can also be used with straight sided, non-tabbed
FPC/FFC

BOperation Methods of Connector and Precautions
Operation Methods Precautions for use
1. FPC/FFC insertion method
Rotate the actuator upward to unlock it
The actuator can be easily operated with
the use of a thumb nail or index finger.
1
1
2. Removing the FPC/FFC
Rotate the actuator upward, then angle the
FPC/FFC upward after the actuator has been
released and remove the FPC/FFC straight out.
1
Insert the FPC/FFC with the contact sur-
face facing down. FH28 is a bottom contact
type connector.
Insert FPC/FFC from the diagonally left
side of the connector. Insert the FPC/FFC
at a diagonal angle and lay it into position.
Insert it until the FPC/FFC is securely
hooked on the positioning area. Check to
see if it is retained by pulling lightly on it.
For detail, refer to the next page.
2
Rotate the actuator downward.
3
Insert the FPC/FFC into the insertion slot
as show below. Improper insertion can
lead to damage and ultimately malfunction.
3
4
Do not pull on the FPC/FFC in an upward
direction, doing this can damage the con-
nector as it is not equipped to handle a
large amount of force in this direction.
When dealing with a higher contact count (80 posi-
tions), be sure to use two fingers to close the actuator
on both sides. Using one finger might not close it
completely and leave an incomplete connection.
The actuator on the FH28 series connector is
designed to open to a maximum of 116 degrees, trying
to open it farther than that will lead to damage.

116˚
5
When inserting FPC/FFC, do not rub it hard on the lower sur-
face of the insertion slot of the connector. Otherwise, the con-
tact hits hard on the FPC/FFC, and may cause the deformation
of the contact or conductor separation etc. of the FPC/FFC.
During the insertion of the FPC/FFC, make sure that

BCautions when mating FFFC/FPC with positioning tabs
Operation Methods Precautions for use
1. Position for insertion
2. Cautions during insertion/mating
Insert the cable into the gap ( ) between the side walls
( ) on both sides of the cable insertion port' and the 'guide
walls ( ) on both sides of the inner part of the connector'
putting the tab of the cable on the gap.
Do not insert the FPC/FFC at an skewed angle (as
shown), this type of action may cause the corner of the
cable to get hooked and deform its contacts.
1
Skwed insertion
Recommended mating method
Do not close the actuator until the FPC/FFC has been
placed into its correct position. If it is sitting on the guides
and the actuator closes onto it, it can cause damage and
alter its performance.
In case you accidentally close the lock with the cable sitting
on the guides, do not move the cable around to make it
seat. Open the actuator immediately and reposition the
cable as explained in “1. Position for insertion” noted
above.
2PC/FFC must not over lap
Incorrectly placed onto
the left guide
Incorrectly placed onto
the right guide
Normal insertion
1Insert the cable
straight from the
diagonally left
side.
2Pull the cable lightly to
yourself and check if
the tab is secured.
3Close the actuator.
Do not close the actuator with
the cable sitting on either guide.
Insert the cable straight into the connector opening and
hook the cable tab onto the guide.
Pull the cable towards yourself with a slight force after
insertion, and close the actuator after confirming that the
cable tab is completely secured.
If it cannot be pulled to out, the cable can be determined to
be inserted into the correct position.
