Hirose : FH52 FPC/FFC connectors robust enough for use in automotive applications


FH52 series: withstands horizontal pull force of 30N


Hirose has introduced the FH52 series, a family of Flat Flexible Cable/Flat Printed Circuit (FFC/FPC) connectors which meet the stringent requirements of automotive applications.

The connector housing incorporates a robust locking structure which ensures that the actuator cannot be removed even under rough operating conditions. The rotating actuator is supported by the tips of the contacts to form a strong hinge point rather than relying on the walls of the housing.

In addition, two metal fittings provide additional support to the actuator from underneath. As a result of these features, the connector can withstand a high pull force of 30N in the horizontal direction when using a ten-position tabbed FPC with a thickness of 0.3mm.

Insertion of the FPC/FFC into the connector is easy because of the wide 110° opening of the actuator.

Special cavities on each side of the connector, known as ‘side catchers’, are provided to hold a tabbed FPC/FFC in place: this retains the connector temporarily, helping the assembler to guide it accurately into place. A firm and clear tactile click confirms that correct locking of the FPC/FFC has been achieved, ensuring the user makes a stable and reliable connection.

Two different types of metal fittings are available. The L-shape type extends from the edge of the housing to allow visual inspection of the soldering process from the top.

In addition, an enhanced PCB retention force of 90N can be achieved.

The I-shape metal fitting is lower in profile and does not extend to the side, saving board space and allowing the connectors to be mounted side-by-side. Its retention force is approximately 50N.
