Backplane connectors are used in various industries as a means of connecting nodes within a system. The MMA21-0201K1 Backplane Connector is a specialized connector designed for applications that require a high degree of vibration and shock tolerance. The main components and working principle of the MMA21-0201K1 Backplane Connector are discussed in this article.

The MMA21-0201K1 Backplane Connector is a two-piece mezzanine style connector that is designed to fit in 1mm, 2mm and 3mm board thicknesses. It has an electroplated gold plated brass housing and accepts printed circuit board (PCB) mounting holes as small as 0.0625” (1.59mm). The contact area consists of 16 contacts on a 0.050” (1.27mm) pitch. The contacts have a floating design, with two gold plated floating pins at each contact point which helps maintain stable contact even under conditions of vibration or shock. The contact area is surrounded by a molded elastomeric insulator to further reduce the effects of variance in contact pressure or vibration.

The MMA21-0201K1 Backplane Connector utilizes the traditional two-piece backplane format, in which the module is mated to the board via two connectors. The module connector is inserted into the board connector from the back side of the board, allowing for direct contact with the board. The flexible contact design allows for both a secure and reliable connection, no matter how much movement is occurring. After insertion, a pushing force is applied to the board to establish firm contact between the module connector and the board connector.

The MMA21-0201K1 Backplane Connector is mainly used in the fields of industrial automation, sensor networks, communication networks, and embedded systems. It is also used in many medical applications due to its high reliability and shock and vibration tolerance. The connector is especially designed to withstand harsh environments, such as explosive atmospheres, where regular connectors may fail due to the effects of the environment on their contacts. The presence of the floating two pins at each contact point, as well as the elastomer insulation around the contact area, make the MMA21-0201K1 Backplane Connector an ideal connector for such locations.
