Backplane Connectors - Hard Metric, Standard are a type of electrical connector specially designed for use in connecting multiple circuit boards together within a computer system, server, or telecommunications equipment. These connectors ensure a reliable and stable connection between the backplane, which is the large circuit board containing the main system buses, and the individual daughterboards that slide into slots on the backplane. The 'hard metric' designation refers to their measurement and sizing standards, which are based on the metric system, ensuring precise and uniform dimensions for compatibility and interchangeability. The primary function of these connectors is to facilitate high-speed data and signal transmission across different boards within the system while supporting the infrastructure that maintains the physical integrity of the electronic assembly.
Main uses of Hard Metric, Standard Backplane Connectors include applications in data center servers, communication systems, industrial computers, and medical equipment where a high density of connections and robust performance is required. These connectors typically feature multiple rows and columns of pins or sockets, high pin-count configurations, and are built to withstand the rigors of frequent mating cycles and harsh operating environments. Characteristics that define these connectors include their durability, excellent signal integrity, and compliance with international standards like IEC and IEEE for electronic interconnects. Common manufacturers of these connectors are TE Connectivity, Amphenol, Molex, Harting, and ERNI, among others.
