Backplane connectors are found in a variety of computing and electronic applications. Used mainly for interconnection between boards, they provide a reliable connection between the different components of a system, allowing safe passage of data and power. Of these connectors, Hard Metric versions are often preferred for their superior durability and high data throughput.Hard Metric connectors support higher data transfer rates than comparable Industry Standard connectors. Also, Hard Metric allows for enhanced functionality within the product. When compared to alternative connectors, Hard Metric generally has lower insertion and withdrawal forces. This type of modular connector has been optimized to offer higher speed, greater bandwidth, and increased signal integrity. The different types of Hard Metric connectors are generally designed to meet stringent requirements for telecom and military applications.

The design of a Hard Metric connector is based on the IEEE 17011512201 standard, which covers physical and electrical characteristics of this kind of modular connector. It is divided into three categories: standard, with 36 contacts, ultra-high-speed, and serial. The standard Hard Metric Connector typically has three rows of 12 pins for a total of 36 contacts. An ultra-high-speed version of the Hard Metric connector has an additional seven pins per row, for a total of 42 contacts per connector. The serial version has three rows of nine pins per row, for a total of 27 contacts per connector. All the contacts within a Hard Metric connector will be of the same type. Hard Metric connectors also feature shielded metal shells, which protect the internal parts of the connection from electrostatic discharge (ESD).

Hard Metric connectors make use of metal latch keys, known as keycodes, to improve the strength and robustness of the connection. Depending on the type of connection, the keycode will be either three- or four-keyed. This allows the connector contacts to be aligned in two or three different orientations, providing a secure, high-performance connection.

When making a Hard Metric connection, the modules themselves must meet certain standards. These include the pitch, type of contact, the density of contact, and the number of positions. Pitch is the distance between the opposing software or hardware pins, and is usually 0.8 mm to 1.27 mm. The type of contact is either coaxial, double row, or right angle. Contact density is measured in double-contact per inch (DPI), and usually ranges from 2 to 16 DPI. Lastly, the number of positions required for a Hard Metric connection can range from six to over two-hundred.

In addition to the physical characteristics, Hard Metric connectors must also meet certain electrical requirements. These include voltage, current, and impedance. Voltage is the operating voltage of the system, and usually ranges from 6 to 20 volts. Current is the amount of current required for the connection, and is usually from 1 to 150 amps. Impedance is the ratio of voltage to current, and is usually from 50 to 200 ohms.

Hard Metric connectors offer enhanced durability, as well as superior data and power transfer capabilities. The physical and electrical design of Hard Metric connectors complies with the demanding requirements for telecom and military applications, making them ideal for achieving high performance in those environments. When compared to other types of connectors, Hard Metric connectors are more reliable, less prone to failure, and provide improved data transfer rates.
