Backplane Connectors - Hard Metric, Standard

Backplane connectors can be divided into several categories. This article will focus on two of them: hard metric and standard.

Hard Metric

Hard metric backplane connectors are used in high-speed and high-performance digital systems. They are designed for data rates up to 10Gbps and are available in 4 to 24 positions. They are extremely reliable and offer a robust connection with minimal signal loss. The contacts are soldered or crimped to the printed circuit board (PCB).

The hard metric connectors consist of a mono-blocking header and a housing. The contacts are preloaded and soldered in place. The contact spacing is 2mm, which enables high-speed signal transmissions. They also feature an asymmetrical shield interface, which shields against noise sources.

These connectors are ideal for aerospace, defense, and electronic products where high-speed, reliable transmission is essential. They are also increasingly being used in consumer electronics, such as medical devices, network routers, and CPUs.

Standard

Standard backplane connectors are the most common type and are used in a wide range of applications. They are designed for data rates up to 622Mbit/s and typically consist of a signal only or power-only connector. These connectors are easier to use than hard metric connectors and offer a more economical solution.

Standard connectors consist of a polarized header and a corresponding PCB housing. The contacts are either soldered or crimped to the PCB. They feature an asymmetric shield interface, which helps reduce EMI/RFI interference. They are also designed to withstand high levels of shock and vibration and are suitable for a range of applications including medical, industrial, and automotive.

In conclusion, hard metric and standard backplane connectors are both reliable and versatile. Hard metric connectors are ideal for high-performance applications and standard connectors are better for low-frequency applications. Both types offer a secure and reliable connection and are designed for a range of applications.
