Introduction

Backplane connectors are one of the most important and widely used components in circuit board assemblies. They are used to provide electrical connections between individual circuit boards, enable data transfer between multiple boards, and even provide power to the system. One type of backplane connector is the hard metric backplane connector, which is the focus of this article.

Description

The hard metric connector, designated 352128-1, is a type of connector based on the standard developed by the European Committee for Electrotechnical Standardization (CENELEC). It was originally developed for use with the European Automatic Military Communications System (EAMCS) but has since become popular and adopted by many other industries.The 352128-1 is a two-part connector with a male (plug) and female (socket) end. The male end has two rows of contacts, while the female end has a single row of contacts. Both sides have removable keys which are used to specify the application. The contacts are spaced 0.8mm apart and are made from brass (for strength). The connector is typically secured with solder and is available in both surface-mount and through-hole versions.

Application Field and Working Principle

The 352128-1 hard metric connector is commonly used in electronic systems that require high reliability and signal integrity. It is often used in data and communication systems, automotive applications, and military systems.The working principle of the connector is relatively simple. When the male and female ends are mated together, the contacts on the male end make contact with the contacts on the female end, forming an electrical path. This allows for the transfer of data and power between the two parts of the system. The keys on both ends prevent the connector from being inserted in the wrong pin orientation, ensuring that the connection is always correct.

Advantages and Disadvantages

The 352128-1 connector has several advantages. It is relatively easy to use, since the contacts are spaced only 0.8mm apart, meaning it takes up less board space. It also has high reliability, as its contacts are made from brass for strength and durability. Finally, it is available in both surface-mount and through-hole versions, making it suitable for a wide variety of applications.However, the 352128-1 connector also has some drawbacks. It is relatively expensive compared to other types of connectors, so it may not be the best choice for low-cost applications. Additionally, its keys are somewhat fragile, so care must be taken when handling and installing the connector.

Conclusion

The 352128-1 hard metric connector is a type of connector based on a standard developed by the CENELEC. It is commonly used in high-reliability electronic systems, and is available in both surface-mount and through-hole versions. It has several advantages, such as high reliability and ease of use, but also some drawbacks such as expense and fragility.
