0.5 mm Pitch, 2.55 mm above the board,
Flexible Printed Circuit & Flexible Flat Cable ZIF Connectors
FH28 Series
■Features
1. Precise FFC/FPC positionining
Large angle of the actuator opening and built-in side guides
in the connector allow straight and exact insertion of the
FPC/ FFC.
2. Rotating actuator
Proven rotating actuator system allows easy ZIF connection,
confirming it with a definite tactile feel. The contact securely
holds the actuator in place, providing reliable normal force.
The unique contact configuration assures that the connector
will remain dimensionally stable over the device’s life.
3. Restricted space applications
Space-saving version has lower profile actuator and smaller
front-to-back dimensions.
4. Standard FFC / FPC thickness
Reliable connection with the use of readily available 0.3 mm
thick FFC/FPC.
5.
Available in 40, 50, 55, 60, 64 and 80 contact positions.
Contact HRS for other contact positions.
6. Board placement with automatic equipment
Flat top surface and supplied on tape-and-reel the
connectors can be easily placed on the PCB.
■Applications
LCD, PDP, notebook computers, HDD, video and audio
equipment, digital cameras, OA equipment and other
devices requiring high reliability ZIF connection of FFC/FPC.
Actuator color: Dark brown

■Overview
Continuing market trends demand higher contact count
connectors while maintaining high electrical/mechanical
reliability, exact FPC/FFC positioning and durability.
Secure actuator lock and retention
Easy FPC/FFC insertion

BOperation and Precautions
Operation Precautions
Do not force the actuator to open beyond its fully
open position. Do not use any type of tool to open
the actuator.

1.FPC/FFC insertion procedure.
Connector installed on the board.
Lift up the actuator. Use thumb or index finger
2
3
Fully insert the FPC/FFC in the connector parallel
to mounting surface, with the exposed conductive
traces facing down.
Rotate down the actuator until firmly closed. It is
critical that the inserted FPC/FFC is not moved and
remains fully inserted.
2. FPC/FFC removal
Fully open the actuator.
Carefully withdraw the FPC/FFC exercising caution
not to deform or damage it.
Do not forcefully bend the FFC/FPC upward.
Consult FFC/FPC manufacturer for the
recommended bend radiuses.
