Introduction

A backplane connector is an electrical component used in the wiring of electronics systems. Backplane connectors provide a means to connect a main circuit board, such as a motherboard, to additional circuits, such as a daughter card or daughter boards. This is commonly used in computer technology, engineering, embedded electronic systems, and other applications.Backplane Connectors - Specialized, are a subset of backplane connectors, and refer to some specific types of backplane connectors. In this article, we will introduce one of the backplane connectors - 70228-112LF. We will discuss its application field and working principle.

Application Fields

The 70228-112LF is a PCIe-based backplane connector mainly used in server, industrial, data storage, and communications applications. It delivers data rates up to 16 Gbps. It is low profile, having 1mm pitch, and has a robust latch. It is suitable for applications in hot-swappable system applications, as well as being used in many data center applications.

Working Principle

The 70228-112LF provides a high speed, low profile contact array for interfacing boards and backplanes. It provides a robust locking mechanism with a simple yet effective latch enabling hot-swapping features. It is fully assembled in a two-piece construction, allowing the contact pins to move freely.The contact pins in this connector are gold plated allowing for superior electrical performance. They also have a small contact area providing a high current rating. This also helps reduce cross-talk between adjacent contacts. The pins provide an impedance-controlled electrical pathway preventing signal degradation.The 70228-112LF also provides a robust EMI/RFI shielding. The shield is designed to minimize destructive RF and EMI interference. It also provides strain relief to the cables and prevents loosening due to vibration.

Features

The 70228-112LF is a low profile PCIe backplane connector that is suitable for high speed data transfer applications. It has a 1mm pitch and is designed to provide superior electrical performance and robust EMI/RFI shielding. The contact pins of this connector are gold plated to provide superior electrical performance and a low contact area in order to provide a high current rating. The pins also provide an impedance-controlled electrical path preventing signal degradation.The robust latch of the 70228-112LF ensures a secure connection with a positive locking action. This provides a robust connection while also allowing hot-swapping features.The EMI/RFI shielding of the 70228-112LF helps prevent data interference and provides strain relief for the cables.

Conclusion

In conclusion, the 70228-112LF is a low profile PCIe backplane connector that offers robust data transferring capabilities and superior electrical performance. It has a 1mm pitch and provides a impedance-controlled electrical pathway. The robust latch and EMI/RFI shielding provide a secure connection and helps prevent data interference. This makes the 70228-112LF an ideal choice for server, industrial, data storage, and communications applications.
