D-sub connectors, also known as D-subminiature or D-sub connectors, are a series of electrical connectors. DEMY9PK87 is a type of connector in the D-sub family. This type of connector is widely used for the transmission of Ethernet signals and in signal processing systems. This article will explain the application field and working principles of the DEMY9PK87 connector.

The DEMY9PK87 connector consists of a shell, two contacts, and two insulators. The shell is designed to provide mechanical support and environmental protection. The contacts are crimped into the connector\'s shell and are usually made out of copper or gold. The insulators are typically made out of polyethylene and they provide electrical insulation. The connector is designed to mate with a complementary connector that has the same shape to ensure a secure connection.

One of the most common applications of the DEMY9PK87 connector is in Ethernet networks. This type of connector is used to connect Ethernet cables to network equipment, such as routers or switches. The connector also has the capability to transmit power, which makes it suitable for applications such as PoE (Power over Ethernet).

Apart from Ethernet applications, the DEMY9PK87 connector can also be used to carry signals for various other applications, such as serial data and video. Since the connector is designed to carry power, it is suitable for applications such as powering cameras or other peripherals. The connector is also commonly used in industrial automation systems, where it can be used to connect sensors, actuators, and control systems.

The DEMY9PK87 connector\'s working principle is quite simple. The contacts on the connector create a mechanical connection with the complementary connector when plugged into it. The contacts then form an electrical connection, allowing signals to be transmitted. The physical shape of the connector also helps to ensure that the two connectors are mated up correctly, so that the electrical connection is maintained.

In summary, the DEMY9PK87 is a type of connector used in D-sub connectors. It is commonly used for Ethernet networks and industrial automation systems, and can also be used for other applications such as video or serial data. The connector consists of a shell, two contacts, and two insulators, and its working principle relies on the mechanical and electrical connection between the mated connectors.
