DIN 41612 is a standard from the European Committee for Standardization covering the characteristics of power backplane connectors and boards used to provide electrical signals for data communication. It defines the physical and electrical characteristics including mating, pinning, and other features that are necessary for interference-free interoperability.

The 535091-5 extension type connection, also known as the "DA 9", is one of the most common and widely used backplane connectors, employed in many mission-critical applications. As the 9th variant of the 535091 series, it is especially well-suited for applications requiring a cost-effective, lightweight backplane connection capable of multi-directional and extended insertion-and-release operations.

With 0.8mm pin pitches, a 5-row design, and 90 pins, this connector is especially well-suited for a variety of applications including LED lighting systems, medical imaging systems, industrial automation systems, automotive systems, and communications devices. Its primary features include highly reliable connection and mating, a compact and slim form factor, and a secure locking system.

The 535091-5 system is based on a three-part mechanism. A shielded female or male-pin contact system comprising two rows of pins connects the mating connectors. An outer casing provides a second connection and ensures proper alignment between the mating connectors. The final component is a latching system made up of two or more latches, which hold the mating connectors securely together.

The main purpose of this connector is to provide a secure, interference-free connection between multiple backplane boards. To achieve this, the connector must act as a shorting device between adjacent pins, preventing interference from other components. The contact system helps to ensure a secure connection between the pins, while the outer casing provides a stable platform for proper alignment and stress relief. Finally, the latching system ensures that the connectors remain firmly locked together until released.

In conclusion, the 535091-5 backplane connector is an excellent solution for many applications ranging from LED lighting systems to automotive systems. Its features provide a secure and interference-free connection between multiple boards, making it an ideal choice for mission-critical applications. Thanks to its easy assembly, cost-effective design, and reliable performance, this connector is increasingly gaining popularity in many industrial and medical applications.
