Backplane connectors are an essential component in electronic devices that require high-speed data transfer and reliable power distribution. These connectors are used to connect printed circuit boards (PCBs) to backplanes, which are large circuit boards that provide a common interface for multiple PCBs. Backplane connectors are designed to provide a high-density, high-speed, and reliable connection between the PCBs and the backplane. In this article, we will discuss the popular backplane connector contact models that are widely used in the industry.

1. DIN 41612 Connectors

DIN 41612 connectors are widely used in industrial applications due to their high reliability and robustness. These connectors are available in different sizes and configurations, ranging from 32 to 96 contacts. The contacts are arranged in a grid pattern, which allows for easy mating and unmating of the connectors. DIN 41612 connectors are designed to handle high-speed data transfer and provide reliable power distribution. They are commonly used in applications such as industrial automation, telecommunications, and data centers.

2. Hard Metric Connectors

Hard metric connectors are a type of backplane connector that is designed to provide a high-density, high-speed, and reliable connection between PCBs and backplanes. These connectors are commonly used in applications such as telecommunications, data centers, and high-performance computing. Hard metric connectors are available in different sizes and configurations, ranging from 60 to 400 contacts. The contacts are arranged in a grid pattern, which allows for easy mating and unmating of the connectors. Hard metric connectors are designed to handle high-speed data transfer and provide reliable power distribution.

3. CompactPCI Connectors

CompactPCI connectors are a type of backplane connector that is designed to provide a high-density, high-speed, and reliable connection between PCBs and backplanes. These connectors are commonly used in applications such as telecommunications, data centers, and industrial automation. CompactPCI connectors are available in different sizes and configurations, ranging from 32 to 144 contacts. The contacts are arranged in a grid pattern, which allows for easy mating and unmating of the connectors. CompactPCI connectors are designed to handle high-speed data transfer and provide reliable power distribution.

4. VME Connectors

VME connectors are a type of backplane connector that is designed to provide a high-density, high-speed, and reliable connection between PCBs and backplanes. These connectors are commonly used in applications such as military and aerospace, telecommunications, and data centers. VME connectors are available in different sizes and configurations, ranging from 32 to 160 contacts. The contacts are arranged in a grid pattern, which allows for easy mating and unmating of the connectors. VME connectors are designed to handle high-speed data transfer and provide reliable power distribution.

5. PC/104 Connectors

PC/104 connectors are a type of backplane connector that is designed to provide a high-density, high-speed, and reliable connection between PCBs and backplanes. These connectors are commonly used in applications such as industrial automation, military and aerospace, and telecommunications. PC/104 connectors are available in different sizes and configurations, ranging from 16 to 120 contacts. The contacts are arranged in a grid pattern, which allows for easy mating and unmating of the connectors. PC/104 connectors are designed to handle high-speed data transfer and provide reliable power distribution.

Conclusion

Backplane connectors are an essential component in electronic devices that require high-speed data transfer and reliable power distribution. There are several popular backplane connector contact models that are widely used in the industry, including DIN 41612 connectors, hard metric connectors, CompactPCI connectors, VME connectors, and PC/104 connectors.
