Backplane connectors, commonly referred to as DIN 41612 connectors, are a form of electronic connector used to interconnect PCBs stacked in an array. DIN 41612 connectors are typically used in telecommunications and data communication systems.Backplane connectors consist of D-subminiature connectors as well as a pair of edge connectors. The most common types of backplane connectors are Type A and Type B connectors. Type A connectors are typically used for connecting printed circuit boards with a relatively low number of signals while Type B connectors are used for higher signal capacities and larger PCBs with more pins.The DIN 41612 connector uses a “D-shaped” design that consists of an array of contacts in an alternating pattern of male and female section. The pins are soldered to the underlying boards and are arranged in rows and columns. The signals are then routed between the two boards using a simple in/out interface.The working principle of a backplane connector is based on a two-layer connection. The top layer contains the socket and the bottom layer contains the pins. When the board is inserted into the socket, the pins are in contact with the pads of the corresponding layer and establish the connections. The signal connection is then completed when the board is pushed into the socket.The contact arrangement of a DIN 41612 connector varies depending on the application. Typically, connectors with up to 96 contacts are used for telecom applications while those with up to 256 contacts are used for high-speed connections. Connectors with up to 416 contacts are used for high-density applications such as computer cards.The main advantages of using DIN 41612 connectors include their easy installation and high reliability. Additionally, they are available in a wide variety of contact arrangements, allowing for customization for applications that require specific contact designs. Furthermore, they are also UL and CSA certified.Overall, DIN 41612 connectors are a popular choice for a variety of applications, particularly in telecom and computer systems. Their reliable and easy-to-install design make them a versatile and cost-effective way to connect printed circuit boards. Furthermore, the wide range of contact arrangements makes them suitable for various application fields.
