Backplane Connectors - DIN 41612

DIN 41612 connectors are a type of Backplane Connectors used in electronics systems to facilitate the connection between components mounted on Printed Circuit Boards (PCBs). The DIN 41612 is a three-row male connector, with low-profile and blind or thru-hole mountings, that provides a solid and reliable connection between multiple boards or cards. The connectors feature polarization guides, as well as combination pins and blind-mate contacts, for edge card, ribbon card and light strip applications. Unlike other backplane connectors, the DIN 41612 utilizes a keying feature to ensure proper mateability.

Application Field

DIN 41612 backplane connectors are primarily used for in-rack applications such as computers, video displays, communication equipment, and server-based systems. In these applications, the connectors are largely used as the intermediaries between the backplane and other functional units. This type of connector can also be found in industrial control systems such as test equipment, as well as in consumer electronics like microwave ovens and audio equipment.

Working Principle

The DIN 41612 backplane connector is a two-part system which consists of the backplane plug and the female socket. The socket is a three-row female connector with comb contacts, and the plug is a three-row male connector with a combination of both standard and insulation holders. The plug is inserted into the socket and a latch mechanism holds it in place. The combination pins on the plug are then mated with the respective contacts on the female socket. The insulated holders prevent shorting and provide EMI/RFI protection.

The DIN 41612 backplane connector features several keying options, such as male-female, female-female and top-bottom keying. This allows for a secure connection that eliminates the possibility of improper mating. Additionally, the mating sequence can be set to meet the needs of the particular application, allowing more flexibility. The insulators are also designed to provide EMI/RFI protection, thus shielding the connected components from harmful interference. Overall, the DIN 41612 backplane connector is an efficient and versatile solution for connecting components in a variety of rack mount applications.
