Backplane Connectors, also known as serial backplane connectors, is a type of electrical connector designed to enable the transmission of data between devices on a backplane board. The 352901-1 series is one of these backplane connectors and is classified as belonging to the Hard Metric, Standard category. This series uses up to 128 contacts and consists of three distinctive parts; the contact, the housing, and the hardware. This article will discuss the application field and working principle of the 352901-1 series.

Application Field

The 352901-1 series backplane connectors are typically used in applications requiring high speed or low-loss signal transmission with a tight package size. Because of their robust construction, these backplane connectors can be used in environments where shock and vibration are significant factors. This series has been especially designed for high performance embedded backplane systems in telecom equipment, PC servers, or medical power systems.

The contact design of the 352901-1 series is optimized for signals with fast-rise times, so it prevents crosstalk and attenuation of signal integrity from anoughly conustrcted mating. Therefore, these backplane connectors are suitable for sophisticated designs, providing the highest signal integrity.

Working Principle

The 352901-1 series is based on a symmetrical design, providing four points of signal contact per row and allowing for a common ground return. This arrangement eliminates the need for return paths via the mounting hardware, resulting in better signal integrity and improved performance.

The contact design of these backplane connectors utilizes a patented axial wiping contact. This ensures that both contact points are wiped simultaneously while mating, providing excellent electrical connection and reliable, long-term performance in high-speed applications.

The housing of the 352901-1 series is designed with support rails integrating it with the mounting hardware. The support rails help to protect the mating connectors from shock and vibration, while also reducing the number of mating cycles before failure. The housing is also designed with cut-outs, allowing for extra flexibility in the configuration.

The hardware of 352901-1 is responsible for securing the connectors to the PCB and providing a positive lock to prevent any movement. This helps to protect the signal integrity of the connection and prevents any physical interruption of the connection.

Conclusion

The 352901-1 series backplane connectors are a sturdy, reliable, and high-performance option for applications requiring high speed or low-loss signal transmission. The contact design, housing and hardware of these backplane connectors offer superior performance and reliability, with features such as a patented axial wiping contact and support rails for improved shock and vibration protection.
