Molex Sentrality Flexible Printed Circuit (FPC) assembly with connectors on both ends.

Sentrality Flexible Printed Circuits (FPCs)

Enabling efficient and flexible power transfer without requiring a traditional board-to-board connection, Sentrality Flexible Printed Circuits (FPCs) are fully terminated FPC cable assemblies with Sentrality power connectors at both ends. These off-the-shelf FPCs weigh less than busbars or conventional cables and support up to 140.0A of current in a durable assembly that is ideal for tight spaces, miniaturized devices, and harsh environments subject to high temperatures and vibration.

Molex flexible printed circuit (FPC) assembly with Sentrality connector termination for board-to-board applications.

Features and Benefits


Miniaturization is driving the need to pack more functionality into less space across a variety of industries and applications. A particular challenge is power transfer in space-constrained packages where confined routing and dense architectures make busbars or traditional wiring difficult to install. Tight bends, heat and vibration can also pose reliability risks for traditional wiring harnesses.

FPCs are ideal for connections in tight spaces. Using high-power connectors and robust materials, FPCs enable designers to achieve efficient, compact power transfer in harsh environments without relying on heavier, bulkier and more complex traditional solutions.

Sentrality FPCs from Molex combine the flexibility of FPCs and the robust, high-current capacity of Sentrality power connectors to provide versatile power delivery in space-constrained applications. These assemblies use flex circuits to carry up to 140.0A in a lighter-weight, more compact format than traditional wires or busbars. Sentrality connectors ensure rugged, thermally stable connections with built-in self-alignment and secure screw hold-downs to deliver reliable performance. The fully terminated assemblies reduce component counts, streamline assembly and simplify system integration.

Compact Power Routing Without Traditional Wire Harnesses or Busbars

Sentrality FPC assemblies weigh less and require less space than busbars or conventional cable harnesses, making high-current power delivery easier in tight spaces, miniaturized devices and applications with routing constraints.

Frequently Asked Questions


What are Sentrality Flexible Printed Circuits?

Sentrality Flexible Printed Circuits are fully terminated FPC cable assemblies with Sentrality power connectors on both ends. A Sentrality FPC is a complete interconnect solution and not just raw flex material. This is the first standard, off-the-shelf FPC interconnect available in this format.

How can Sentrality FPCs help with my design?

Sentrality FPCs help improve designs by replacing heavier, bulkier cable assemblies or rigid busbars with flexible, lighter-weight solutions. These FPCs are ideal for miniaturized devices and space-constrained packages, enabling flexible routing and durable construction that minimizes discrete components, labor and potential failure points. Incorporating Sentrality FPCs enhances design freedom and enables more compact, versatile and reliable architectures.

What is the advantage of a Sentrality FPC over traditional wiring?

Sentrality FPCs improve on traditional wiring by providing a lighter-weight, easier-to-assembly connectivity solution. Better bending/flexing capability and a compact footprint make these solutions ideal for ensuring consistent electrical performance in space-constrained and dynamic applications.
