DIN 41612 is a series of backplane connectors designed for connecting PCB boards in all types of industrial and commercial applications. DIN 41612 connectors, also known as DIN-style connectors, are characterized by their shape and the distance between the contacts. They feature a two-piece design, with each piece having two rows of contacts, one row on each side of the backplane.

The DIN 41612 is designed for board-to-board applications, offering a reliable connection between two printed circuit boards. It has two levels of connections, which correspond to two levels of signal integrity. The upper level is designed for signals that require high speed and low noise, such as clock lines and analog signals. The lower level is designed for slower signals or power lines. The connector also includes several common features such as a grounding strip, keyed mating, and robust polarization.

The DIN 41612 connector is available in a variety of sizes, including single and double row, as well as various pin counts from 10 pins to 60 pins. The contacts are generally rated for up to 5 amps, making the connector well suited for power applications. The standard materials used for the contacts are brass or phosphor bronze, and the PCB pads are typically made from tin-plated copper.

The main benefits of DIN 41612 are its ability to provide robust board-to-board connections and its interchangeability with most other backplane connectors. It is also notable for its small size, which makes it ideal for applications where space is a concern. Additionally, the connector has low insertion and extraction forces, allowing for easy and reliable mating and unmating.

The working principle of DIN 41612 is relatively simple. The plug and socket halves of the connector are mated together, with the contacts from one sitting in the recesses of the other. The contacts are then secured by the connector’s clamping system, which typically uses a screw to ensure the contacts are firmly held in place. The result is a secure connection that withstands a wide range of environments and vibration levels.

DIN 41612 connectors are widely used in industrial and commercial applications, particularly where board-to-board connections are required. They are also used in the medical industry for high-quality, reliable connections, as well as in the telecommunications and automotive industries. DIN 41612 offers a reliable connection that is strong enough to withstand vibrations and other environmental factors, making it an ideal choice for applications where dependability is paramount.
