A DF18E-50DP-0.4V(52) rectangular connector is a type of mezzanine, or board-to-board connector. It is mainly used to connect two printed circuit boards (PCBs), providing power, signal, and mechanical connection. It belongs to the array, edge type, mezzanine family of connectors that are engineered by companies like 3M or Molex.

The DF18 designation stands for the total number of copper contacts within the connector. In this case, the number 18 denotes that the connector has 18 signal contacts (4 rows of 4 each), as well as one power (50D) contact and two grounds (four contacts in each ground). The 0.4V indicates the voltage the connector is rated to handle, while the (52) suggests that the connector is made from a polyamide blend of the type 3600-02, a UL-certified Nylon 66.

Array connectors like the DF18E are designed to stack together, helping save board space but also allowing the device to interconnect with multiple application boards. The connectors are also designed to reject foreign objects, with each contact covered by a slide-in protection plate.

The DF18E-50DP-0.4V(52) connectors feature a square top panel, which provides greater bracing strength. This allows the stacked connector to support heavier board arrangements without compromising electrical performance or connector integrity. To prevent accidental contact and possible short circuiting, the power contact, signal contacts, and ground contacts remain insulated from each other.

The DF18E-50DP-0.4V(52) connector utilizes a ‘snap-in’ design, meaning users can easily connect and disconnect the connector without any additional tools or hardware. The snap-in design ensures that the connector remains secure even after multiple connections and disconnections. For added assurance, the connector can be secured with an optional screw. This creates a strength and security similar to a threaded connection.

The DF18E-50DP-0.4V(52) connector is easy to install, and the connections will remain secure as long as the design is properly specified and implemented. This makes it a popular connector for a variety of applications, including industrial electronics, automotive, medical, and other applications.

In summary, the DF18E-50DP-0.4V(52) rectangular connector is a type of array, edge type, mezzanine connector designed and manufactured by 3M and Molex. It is primarily used to connect two printed circuit boards, providing power, signal, and mechanical connection. The connector features a snap-in design, allowing easy connectivity without special tools or hardware. The connector is also designed to reject foreign objects, while its top panel design provides additional strength and stability to the stacked connector.
