As smart hardware and precision electronics evolve toward miniaturization and higher integration, connector design has also become increasingly refined. The KH-FG0.5-H2.0-21PIN, developed by Kinghelm, is a high-performance FPC connector engineered specifically for ultra-thin devices and high-density PCB layouts. With its superior mechanical design, electrical performance, and assembly efficiency, this model meets the stringent requirements of modern lightweight, high-functionality devices, offering engineers more flexible layout options and becoming a preferred solution across the industry.

This model features an SMD surface-mount structure with an ultra-fine 0.5mm pitch, allowing for compact, high-pin-count cable arrangements. As component density continues to increase, the 0.5mm high-density design significantly improves PCB space utilization, making it ideal for more compact and lightweight motherboard configurations. The 21-pin configuration provides ample interfaces for high-speed signal transmission, data collection, and multifunctional module interconnection. It is widely used in smartphones, tablets, smart bands, industrial terminals, and portable medical devices.

One of the product’s standout features is its flip-lock design, which—combined with precision-molded housing—ensures easy insertion and secure fastening of flexible flat cables. Once the flip-lock is closed, it firmly presses the contact pads, enhancing connection strength and vibration resistance. This reduces risks of disconnection and signal loss caused by poor contact, meeting the demands of long-term, high-intensity operation. The bottom-contact structure optimizes the signal path to reduce EMI and signal reflections, thereby improving overall communication quality.

In terms of mounting, the KH-FG0.5-H2.0-21PIN FPC connector uses a horizontal mount layout with a 2.0mm profile height, aligning with the industry's strict thickness control standards for slim devices. It supports 0.3mm-thick FPC cables, ensuring compatibility with mainstream FPC standards. The tape-and-reel packaging improves safety in transport and storage, and is fully compatible with modern SMT automatic assembly lines—reducing manual handling, boosting throughput, and improving production yield.

This model operates reliably across a temperature range of -25°C to +85°C, making it suitable for diverse environmental conditions—from outdoor terminals in freezing regions to industrial automation modules in high-temperature settings. Its broad temperature tolerance allows it to serve both consumer electronics and industrial applications where performance stability is critical.

In real-world applications, the KH-FG0.5-H2.0-21PIN FPC connector is commonly integrated into smartphone front camera modules, TWS earbud charging cases, drone image transmission modules, automotive infotainment displays, and sensor cabling in wearable devices. It ensures high-frequency, high-speed transmission while reducing device size, contributing to more competitive end products.

With years of expertise in the connector industry and ongoing investment in R&D, Kinghelm is committed to delivering high-precision, high-reliability connectivity solutions. The KH-FG0.5-H2.0-21PIN is another standout product in its FPC connector lineup. Its refined construction, dense pin layout, and excellent compatibility make it ideal for next-generation smart device designs—enabling product innovations in lightweighting, high-speed performance, and modular integration.
