Product Overview and Key Features

The KH-FPC0.5-H2.0SMT-50P-QCHF is a surface-mount FPC connector designed for high-density signal transmission. It features a 0.5mm pitch and supports 50 contact positions, enabling efficient signal routing within limited PCB space. The product is delivered in tape-and-reel packaging, making it suitable for automated assembly processes and consistent placement during production.

The connector adopts a horizontal mounting (right-angle SMT) configuration, which helps reduce vertical space usage and supports compact PCB layouts. With a board height of 2mm, it is well suited for slim electronic devices where internal space is constrained.

Flip-Lock Mechanism for Secure Connection

This model utilizes a flip-lock (hinged) locking structure. The flip cover allows easy insertion of the flexible flat cable (FPC) and provides a clear mechanical feedback during operation. Once closed, the structure applies uniform pressure on the cable, helping maintain stable contact and reducing the risk of loosening during use.

The design also supports repeated insertion and removal, making it suitable for applications that may require maintenance or cable replacement over time.

Dual-Side Contact Design for High-Density Transmission

A key structural feature of this connector is its dual-side contact configuration, also known as top and bottom contact. This design allows both sides of the FPC cable to engage with the connector contacts, effectively increasing signal density within the same footprint.

By accommodating 50 signal lines in a compact interface, the connector supports complex circuit connections and helps maintain signal integrity in high-frequency transmission scenarios. The multi-point contact structure contributes to stable electrical performance by reducing variations in contact resistance.

Material and Electrical Characteristics

The contacts are made of phosphor bronze, offering a balance of mechanical elasticity and electrical conductivity. This ensures consistent contact force even after multiple mating cycles. The contact surface is gold-plated, which helps reduce oxidation and supports long-term connection stability.

The connector is rated for 50V and 500mA, making it suitable for low-voltage signal transmission in a wide range of electronic systems. It is compatible with 0.3mm thick FPC cables, aligning with commonly used flexible cable specifications.

Thermal Performance and Environmental Adaptability

The operating temperature range of this connector is from -40°C to +85°C. This range allows the product to function in both low-temperature startup conditions and elevated temperature environments during operation.

Such thermal tolerance makes it applicable in devices exposed to varying environmental conditions, including outdoor equipment and enclosed electronic systems with heat accumulation.

Application Scenarios Across Industries

The KH-FPC0.5-H2.0SMT-50P-QCHF is designed for applications that require compact structure and multi-signal connectivity. In security and surveillance systems, such as HD camera gimbals, it supports multiple signal paths within limited space.

In automotive electronics, including central control displays and instrument modules, the connector fits designs that demand stable connections and efficient space utilization. In consumer electronics, such as gaming controllers and advanced drones, it enables lightweight and compact internal layouts while maintaining reliable signal connections.

Conclusion and Future Outlook

As 5G communication and IoT devices continue to evolve, internal electronic architectures are becoming more integrated and space-sensitive. Connectors must adapt to these trends by offering higher pin counts, smaller sizes, and stable performance.

Kinghelm continues to expand its FPC connector lineup with variations in pitch, pin count, and locking structures. Future developments will focus on supporting diverse application needs while maintaining consistent electrical and mechanical characteristics in compact designs.
