Rectangular connectors, such as DF12D(3.5)-20DP-0.5V(81), are widely used in electronics and other industries. These connectors have many applications in various fields. In this article, we will discuss the application field and working principle of the DF12D(3.5)-20DP-0.5V(81) connector.

DF12D(3.5)-20DP-0.5V(81) connectors are used in mezzanine (board to board) applications. Mezzanine connectors are typically used to enable two circuit boards to be stacked together. The DF12D(3.5)-20DP-0.5V(81) connector is designed to provide high-density connection between multiple boards, and it is compatible with a wide range of applications. It provides reliable electrical connection with a 0.5V voltage rating for improved performance and reliability. The connector supports up to 20 board-to-board contacts and features a robust shell to protect against environmental stresses.

The DF12D(3.5)-20DP-0.5V(81) connector’s working principle is based on the principles of edge connectors. Edge connectors are constructed with a printed circuit board (PCB). The edge connector has two strips, each called an edge plane, which run along the edge of the PCB. The DF12D(3.5)-20DP-0.5V(81) provides a robust connection between the two boards through the edge plane with the aid of two springs.

The contact of DF12D(3.5)-20DP-0.5V(81) connector consists of two blades or contacts. The first blade is the primary contact or "fixed" contact, which is permanently attached to the board. The second blade is the secondary or "floating" contact, which is supported by the mechanism of two leaf springs.

The edge connector is connected by placing the primary contact of the board in the cavity of the connector. The secondary contact is then moved into the cavity and secured to the board using two small screws. Once the secondary contact is secured, the edge connector is able to provide a reliable electrical connection to the board.

The DF12D(3.5)-20DP-0.5V(81) connector is a highly reliable and cost-effective solution for a wide range of applications. It provides a high-density, reliable connection with a 0.5V voltage rating for improved performance and reliability. The robust shell and robust contacts make it resistant to environmental stresses, making it an ideal choice for many applications.
