D-Sub connectors are one of the oldest types of connectors used in many different electronic devices. The most popular models today are the DBE-25P-K87 series. These connectors are designed to be used in applications where fast and reliable connections are vital, such as in computers, network connections and power supplies.

The DBE-25P-K87 is a 25-pin, 8-row female connector with a shell size of 22mm. It has a maximum wire gauge of 17AWG and a voltage rating of 250VAC. It is designed to accommodate small diameter wires with a minimum pin length of 0.15mm and a maximum pin length of 1.05mm. Each connector is equipped with two backshells, which provide additional protection against electromagnetic interference (EMI) and radio frequency interference (RFI).

The DBE-25P-K87 utilizes a variety of contact types to ensure reliable and secure connections. These can be crimped-on or soldered-on contacts, depending on the needs of the installation. The contacts used are typically made of nickel-plated brass or aluminum. They feature a delicate c-shaped design that offers superior connection quality. Additionally, these connectors are designed to meet IP67 waterproofing requirements, ensuring their use in even the toughest environments.

The DBE-25P-K87 connectors are mainly used in data transmission applications. One of the most common applications is for computer networks, where several devices need to be interconnected in order to exchange information. USB ports and other computer-related peripherals often rely on the use of these connectors as well.

The working principle of these connectors is quite simple. When two connectors are mated, the contact pins form an electrical connection. This allows for the exchange of signals and power between the two devices. The two backshells provide additional protection against EMI and RFI. Additionally, the connector\'s design also ensures that the connection remains secure and reliable.

In conclusion, the DBE-25P-K87 series of connectors are designed to provide a reliable and secure interconnection solution. They are ideal for use in data transmission applications, particularly in computer networks. The connectors are designed to meet IP67 waterproofing requirements, ensuring their use in even the harshest of environments.
