D-Sub Connectors

D-Sub connectors are a type of electrical connector, and are commonly used for computer hardware, such as hard drives, motherboards, and network switches. D-Sub connectors are often used in serial data transmissions, such as in RS-232 or RS-422 communications. The connectors are named after their distinctive D-shaped shell. D-Sub connectors come in a variety of sizes and configurations, with the most common being the DE-9 connector.

DM5P1P1A5NA191K87

The DM5P1P1A5NA191K87 is a 9-pin connector with an industry-standard shell size and contact configuration, making it a common choice for many applications. The connector has a two-piece shell structure which includes an insulator with metal insert and a plastic housing which encloses the pins. The connector is constructed from durable plastic and is capable of providing reliable strain relief for extended applications. The connector is rated to 6.5A at 600VAC and can handle operating temperatures up to 100°C.

Application Field

The DM5P1P1A5NA191K87 connector is designed for low and high current applications, such as communication, audio/video, industrial control, and automation systems. It is suitable for connecting electronic and pneumatically operated devices, motors, relays, and transformers. Additionally, the connector can be used in environments where there is a presence of water, oil, acidic vapors, and dust.

Working Principle

Due to the two-piece shell structure, the DM5P1P1A5NA191K87 connector has two different ports for power and signal. The power is supplied from the back of the connector, through the metal insert, and to the socket contacts on the front of the connector. The signal is then transmitted from the socket contacts to the pins on the front of the connector. The pins have a spring-type contact which allows for a secure connection while also providing flexibility and longevity. Furthermore, the connector is designed to have a locking mechanism in order to prevent accidental disconnection of the connection.
