Backplane connectors, due to its variety of design possibilities and physical solutions, have enabled versatile connections and communications between different devices and components. In particular, 646956-1 backplane connector is a specialized type of backplane connectors that offer various advanced features and functionalities that have made them a popular choice in many applications. This article will provide an overview of the application field and working principle of this connector type, as well as the factors to consider while selecting them.

646956-1 backplane connectors are widely used in applications including medical, aerospace, avionics, airborne, and military. They are suitable for board-to-board connections and provide a variety of mating options such as screwdriver mating, direct interfacing of multiple components, and more. In addition to its high connection reliability, these connectors are also resistant to shock, vibration, and other mechanical and environmental stresses. Such features provide a wide range of applications and usages, both for commercial as well as industrial purposes.

The working principle of 646956-1 connectors are based on the 9mm pitch surface mount technology. It works on the concept of ‘insulation displacement contact’ (IDC) by inserting insulation-displaced conductors into the corresponding terminals in a ‘direct plug-in’ fashion. This unique design and feature allows for easier and faster connections, which increases productivity. The contact resistance in this type of backplane connectors is improved by making contact in the mid-wire, reducing the potential of contact resistance problems.

The selection of any backplane connector should be based on the requirements of the application. 646956-1 connectors are appropriate for highly reliable and efficient data transmission. When selecting these connectors, several factors should be considered: pitch size, number of contacts, number of rows and columns, and height. Pitch size, which is the pitch distance of the contact pins or sockets, is important to ensure the correct distance between the pins/sockets. The number of contacts that the connector can handle and its capacity to provide row and columns, is essential for data transmission in complex systems. And finally, the size of the connector\'s height (also referred to as ‘stack height’) should be considered for accommodating more layers and connections in a compact space.

In conclusion, 646956-1 backplane connectors offer a wide array of applications due to its features and functionalities. The advantages such as higher connection reliability, shock/vibration resistance, and faster and easier connections, have made these connectors an ideal choice for many applications. While selecting them, several factors such as pitch size, number of contacts, number of rows and columns, and height should be taken into consideration.
