Greenconn Open Card Edge Board-to-Board Connector for Compact PCB Applications

With the ongoing trend toward miniaturization and modularization of electronic systems, the demand for high-density interconnects between PCBs continues to increase. In applications such as smart buildings, industrial control, sensor modules, and linear lighting systems, connectors are required not only to ensure stable power and signal transmission, but also to meet stricter requirements for compact design, assembly precision, and routing flexibility.

Such as elevator sensor systems, where continuous operation is exposed to vibration, frequent start-stop cycles, and long-term mechanical stress, interconnection solutions must deliver higher levels of reliability, space efficiency, and modular design capability. In compact PCB layouts in particular, achieving higher contact density while maintaining stable and reliable connections has become a key focus in connector design.

Greenconn CBFA201: Open Card Edge BTB Connector in Compact PCB Modules

Open-Ended Card Edge Design for High-Density PCB Interconnects

To address the requirements of high-density PCB module interconnection, Greenconn introduces the CBFA201 open-ended card edge BTB connector series.

The CBFA201 series features a 2.0mm pitch design and a dual-sided contact structure, enabling increased contact density within a limited footprint while maintaining stable electrical performance. The open-ended structure further helps reduce overall connector length, making it well-suited for compact electronic designs.

A central polarizing rib is integrated into the connector design to support PCB pre-alignment during mating, improving assembly accuracy and connection reliability. In addition, the design supports mixed power and signal routing, offering greater flexibility for diverse system architectures.

Key Design Features

· Miniaturized design: contact length as low as 1.0mm for compact PCB layouts

· Dual-sided contact structure: increased interconnect density for standard 1.6mm PCBs

· High current capability: up to 3A per pin for 4/6-position configurations

· Precise mating alignment: central polarization design improves assembly stability

· Flexible expansion: supports coplanar and extended card edge configurations

· Mixed routing capability: supports combined power and signal transmission
