The DF40JC-24DP-0.4V(53) rectangular connector belongs to the Arrays, Edge Type, Mezzanine (Board-to-Board) class of connectors. As its name suggests, it is an array edge type mezzanine with 24 dual-row pins arranged in a 0.4 inch pitch. The DF40JC-24DP-0.4V(53) connector is used in applications such as servers, digital video, and aerospace systems, where requirements such as mechanical stability, temperature cycling, and vibration are stringent. The connector is suitable for both high-speed and low-speed data rates. The rated current of the connector is 4 Amps and the operating temperature range is from -25°C to 85°C.

The DF40JC-24DP-0.4V(53) connector features two primary parts: a housing and a contact. The housing is composed of an insulating dielectric made from a high temperature polymer, which is designed to withstand extreme temperature variations and provide an excellent electrical insulation. A latch is included in the housing to ensure that the connector is properly mated. The contacts of the connector have gold-plated flat spring contacts which ensure reliable contact during mating and unmating and provide a low contact resistance. The contacts are soldered into the board using a through-hole type soldering technique.

The working principle of the DF40JC-24DP-0.4V(53) connector is based on the concept of electrical continuity. When the connector is inserted into its mating receptacle, the flat spring contacts are compressed, creating a conductive path between the two circuits and allowing electrical signals to be transmitted across the interface. The compression of the contacts allows the spring to return to its original shape after the connector is unplugged, thus ensuring a solid connection.

In order to ensure a reliable connection, the DF40JC-24DP-0.4V(53) connector is designed with two keying options: a single-position key and a double-position key. The single-position key ensures the correct insertion of the connector into the mating receptacle, while the double-position key ensures that the contact is properly seated in the double-row configuration. The connector also features multiple mounting options, including a rear-mounted, front-mounted, and surface-mounted configurations.

In conclusion, the DF40JC-24DP-0.4V(53) connector provides a reliable electrical interface in high-speed and low-speed data applications. It has two keying options and multiple mounting options, making it suitable for a variety of applications. The connector is robust and durable, making it an ideal choice for long-term use in a wide range of harsh environments.
