Backplane connectors are an important type of electrical connector used to provide data and/or power connections between boards in a wide variety of applications. DIN 41612 is a specific type of specialized backplane connector that is widely used in industrial and embedded applications. This article provides an overview of the DIN 41612 backplane connector, its application field and working principle.

Overview of DIN 41612

The DIN 41612 connector is a popular alternative to other types of backplane connectors. It was developed by the German standards committee DIN (Deutsches Institut für Normung). The DIN 41612 backplane connectors are compatible with the power connector systems designed for the earlier European standards, and are also used in military and medical applications. The connector series includes a wide range of sizes and types, including through-hole, surface mount, and shroudedheaders. The standard supports both 3 and 2 row horizontal versions, with up to 7 columns per row.

The physical interface of the DIN 41612 connector system is identical to the connector system used in the earlier European standards, but with improved EMC shielding in order to meet demanding military and medical applications. The connectors are also equipped with a locking device such as a screw, to ensure secure connection between the two mating sides. The contacts in the connectors can handle up to 8A/50V per contact, and are designed to meet safety and reliability requirements. The connectors are available in both through-hole and surface mount versions, with the former being the main application areas.

Application Field of DIN 41612

The DIN 41612 connector is widely used in many industrial applications such as robotics, transportation, telecommunications, medical equipment and consumer electronics. The connector is also used in many embedded applications including embedded computers, military and aerospace applications. It is commonly used to provide power and data connections between multiple boards, and is often used as part of a control panel or backplane system to connect components of the system.

The use of backplane connectors like the DIN 41612 is increasing in industrial applications. This is due to the increasing number of components and the need for more efficient ways to connect them. Backplane connectors provide a reliable connection between multiple components and boards, making them ideal for use in applications such as automotive control systems, industrial and medical equipment and more.

Working Principle of DIN 41612

The DIN 41612 connector is a spring-loaded, card-edge connector that provides a secure electrical connection between the edges of two PCBs. The female side of the connector consists of contact strips that are soldered directly onto the PCB. The male side of the connector is made up of contact pins attached to the edge of the board. When the board is inserted into the female side of the connector, the contact pins make contact with the contact strips and provide an electrical connection. The connection is secured by a locking mechanism such as a screw, which keeps the boards firmly connected. The contact pins are also insulated to prevent any damage to the surrounding circuitry.

To ensure secure connection between multiple boards, the electrical contact is activated when the board is inserted and the contact strips are fully engaged. The spring-loaded mechanism makes sure that the contact pins are always making contact with the contact strips. To prevent accidental disconnection, the locking mechanism also provides a secure connection between the two boards. The DIN 41612 is designed for easy installation and maintenance, making it suitable for use in a range of applications.

In summary, the DIN 41612 backplane connectors are a popular type of connector used in many industrial applications. They are used to provide reliable data and power connections between boards, and can be used in a range of applications including embedded computers, industrial control systems, medical equipment and consumer electronics. The connectors provide a secure connection with a spring-loaded, card-edge connection and a locking mechanism, and are available in through-hole and surface mount versions. With their strong contact pins and flexible design, the DIN 41612 backplane connectors are an ideal choice for many industrial applications.
