DIN 41612 is a standard for backplane connectors used to create connections between printed circuit boards (PCBs) and devices within a larger system. Developed by Deutsche Industries Normen (DIN), the standard defines the dimensions, shape and performance characteristics of the connectors used to make these connections.

The DIN 41612 backplane connectors are characterized by their ruggedness and high flexibility. These standard connections can withstand shocks, vibrations, extreme temperatures, and other harsh environmental conditions. The DIN 41612 connectors are used in a variety of applications, ranging from testing and manufacturing to telecommunications and aerospace.

The DIN 41612 connector is typically comprised of an external housing that contains several major components and connections. These components, such as a female board pattern, a grounding lug, and mating pins, allow a variety of electrical and mechanical connections to be made. The housing also contains sealing components, such as gaskets and seals, to protect the connections from contact with external moisture and debris.

The connectors are designed with a two-part contact arrangement. The contacts are made up of size-specific pins that penetrate through the external housing and make contact with the mating pins or the female board pattern on the opposite side. The pins can be moved, allowing them to make better contact with both the female board pattern as well as the mating pins. The different pin sizes, as defined by DIN, are 9, 12, 15,17, 21, and 40. Each size refers to the length of the pins when connected with a mating connection.

The primary connections that the DIN 41612 connector enables are male-to-female, male-to-male, female-to-female, male latching and female end-on connections. Additionally, the connectors can be used to create blind mating connections, which allow pins to be inserted from opposite sides of the connector body. This design also allows pins to be connected to the female board pattern without being seen from the outside, allowing for increased wiring flexibility and user safety.

The applications for DIN 41612 backplane connectors are as diverse as the devices they connect. For example, the connectors are used in testing and manufacturing, audio/visual, telecommunications, computing, medical and industrial equipment, and aviation and aerospace. The robust construction and flexibility of these connectors make them well suited to a variety of challenging applications.

In summary, DIN 41612 connectors are used to create robust electrical connections between printed circuit boards (PCBs) and devices within a larger system. The connectors enable a variety of connections, such as male-to-female, male-to-male, female-to-female, male latching, and female end-on connections. The connectors are typically comprised of an external housing that contains several major components and connections to ensure secure electrical contact and protection from external moisture and debris. The DIN 41612 connectors are used in a variety of applications, ranging from testing and manufacturing to telecommunications and aerospace, due to their ruggedness and high flexibility.
