17021254209 Backplane Connectors - Hard Metric, Standard

Backplane connectors are a type of physical connectors that are designed to join electrical circuit boards together. They are available in different configurations varying by thepin locations and contact types. In terms of their application, backplane connectors are widely used in computers, communications, industrial automation and consumer electronics. When it comes to backplane connectors, there are two distinct categories, namely hard metric and standard. This article provides an overview of each type, its benefits and applications.

What are Hard Metric Backplane Connectors?

Hard metric backplane connectors, also commonly referred to as “HM” connectors, are designed according to IEC 61076-4-104 standards. These standards are particularly important when it comes to mounting signal integrity and electrical components in high-density electronic systems.These connectors have a more significant number of connection points compared to standard connectors, ranging from 12 to 60 with the help of an extender. Generally, the pins on a HM connector are divided into power and signal lines, enabling the equipment to get more power and data inputs and outputs.

Benefits of Hard Metric Connectors

By using backplane connectors with higher pin-counts, higher pin densities and better contact materials, the overall measurements of printed circuits, backplanes and system functions become much more accurate. This increases the overall performance and reduces the costs involved in procurement. Apart from this, hard metric connectors are also hot-pluggable, meaning that you can conveniently plug and unplug them without having to worry about damaging the circuit. This means that you can easily add or remove a connector without having to power down the system.

Application of Hard Metric Connectors

Due to their higher pin density and greater flexibility in terms of pins and contact types, hard metric backplane connectors are used for high-end applications that need little space and increased performance. Moreover, they are ideal for situations where crosstalk and radiation need to be minimized.Plus, HM connectors are also widely used in applications such as telecom equipment, I/O modules, aerospace, military and industrial automation systems, and even PC motherboards.

What Are Standard Backplane Connectors?

On the other hand, standard connectors are designed to consolidate multiple devices onto a single printed circuit board. These connectors are manufactured in two distinct categories known as vertical and right-angle connectors. Since they have a smaller number of connection points and pins, these connectors cannot match the measurements and performance of hard metric connectors. In most cases, a single standard backplane connector has 10 to 40 pins on it.

Benefits and Applications of Standard Connectors

Standard backplane connectors are generally easy to install and widely available. This makes them a perfect choice for basic applications that do not require high performance or accuracy. They are mostly used to connect multiple components in order to share power and data between them. This makes them ideal for creating simple internal systems with low cost. Additionally, they are widely used in controlling robotics, power supplies, communications networks, and other electronics.

Conclusion

To sum up, backplane connectors are used to join electrical circuit boards together in various applications. There are two distinct categories of backplane connectors, including hard metric and standard. Hard metric connectors are designed according to IEC 61076-4-104 standards, and feature more connection points as compared to standard connectors. These connectors are ideal for high-end applications where space and performance is of the essence. Standard connectors offer more versatility and availiability as compared to hard metric connectors, and are best suited for basic applications. They are mainly used in robotics, power supplies, communications networks, and other electronics.
