Backplane connectors provide efficient connections between devices such as computers, boards, cables, and other machinery. Connectors of this type are commonly used in applications such as: server storage systems, computer workstations, test and measurement equipment, storage systems, automated assembly systems, telecommunications, industrial control, medical equipment and consumer electronics, among others. DIN 41612 connectors are suitable for data transmission speeds from DC up to 10 Gbps. They have been designed to be suitable for high density applications by providing high performance and reliable connectivity.

The DIN 41612 standard, also known as "Connectors for electronic equipment with a symmetrical arrangement of connecting contacts", is a European standard dealing with backplane connectors. It defines the socket type connectors with a symmetrical arrangement of 2 or 4 contact rows. The size of the socket type connectors range from 6 positions to 108 positions, with 2 to 32 contact rows that can be fitted with standard rectangle, edge or "h" pin type. The connectors meet the highest requirements for sealing, durability and vibration resistance as well as temperature and current rating strength.

The DIN 41612 backplane connectors provide very high signal integrity in the form of low insertion/extraction forces, high mechanical resistance, reliable customer contact and secure contact retention. They are designed to meet the most stringent requirements by providing superior moisture resistive seals and full signal portability to minimize signal crosstalk and distortion. They have low mating forces that enable easy and effortless connection and disengagement.

These connectors are available in two distinct designs. The first is a two-row connector design with either 0.3mm or 0.5mm pitch. The second design is a four-row connector design with 0.4mm pitch. Both of these designs feature high density connections and provide very low crosstalk and insertion loss. Additionally, both are designed to provide extremely low interconnectivity noise and high reliability in harsh environments.

The DIN 41612 backplane connectors are commonly used in Ethernet compliant communications systems, military applications, telecommunications systems, servers, storage systems, printers and fixtures. Some of the benefits of using this type of connector include: improved signal integrity, rugged design for harsh environments, superior board and cable strain relief, swing action mating that enables easy insertion and extraction, and improved EMI for high-frequency signals.

The working principle of this type of connector is based on the simple principle of electrical connection by means of a contact. When a connection is made, an electrical current passing between the two parts creates a physical connection. As the connection is made and the current passes, the contact maintains a secure and reliable electrical connection.

In order to ensure that the connection is secure and reliable, the DIN 41612 connectors feature a kinematic locking system. This system ensures that the two parts are securely fastened together when in contact. This locking system also prevents accidental disconnection and provides reliable operation in the presence of shock or vibration. Additionally, this locking system on the socket contacts maintains contact resistance by providing a wide contact surface between the two opposing surfaces.

The increased demand for smaller size and higher transmission speeds has led to the development of high-speed DIN 41612 connectors. High speed DIN 41612 connectors provide up to 10 Gbps data transfer rates, depending on the configuration. These connectors feature a low contact resistance that enables improved transmission of high-speed signals with fewer errors. They also feature a robust metal shell for increased durability in harsh environments.

In summary, the DIN 41612 backplane connectors are suitable for a variety of high-speed data transmission applications, as they provide a secure connection, high performance, reliable customer contact, low insertion/extraction forces, ruggedness and durability. The locking system on the socket contact maintained contact resistance, and the high-speed versions provide up to 10 Gbps data transfer rates. The wide range of sizes and contact arrangements provides great flexibility and compatibility for a host of applications.
