D-Sub, D-Shaped Connectors - Housings is the broader category that contains the 208743-4 application field and working principle. This popular series of connectors has its basic roots in the 1940s, but started being mass produced in the late 1950s. It was originally designed for military applications, but quickly found its way into the consumer market. Today it is still widely used in a variety of consumer and industrial applications.

The 208743-4 is a standard-size D-Sub connector that uses 2 rows with 25 pins. It is a two-piece design that consists of the housing and the contacts. The lock mechanism uses a knurled thumbscrew with a flat polarizing surface on the outside.

The 208743-4 D-Sub connector housing is constructed of polybutylene terephthalate (PBT) plastic. The contact mating area of the housing is on the underside with the pin/socket arrangement facing outwards. Each contact in the housing has a stamped and formed flat contact and is covered with a plastic insulator/strain relief. This allows for secure, EMI-resistant connections. The contacts are arranged with 5 pins and 5 sockets in a row.

The 208743-4 is suitable for a variety of applications in both consumer and industrial products. It is ideal for high-power applications such as industrial fieldbus networks, computers, and communications systems. Its lockable design makes it an excellent choice for use in harsh, hostile environments, such as inside racks and cabinets in industrial settings. The D-Sub connector is also used in applications such as cameras, motor controls, and robots.

The working principle of the 208743-4 is quite simple. When two compatible 208743-4 connectors are connected, the contacts within the housings come into contact, forming the electrical connection. The flat polarizing surface of the thumbscrew ensures that the two connectors are securely connected and that the contact pins and sockets are correctly aligned. The thumbscrew is then tightened with a small wrench to make the connection secure and to ensure a reliable connection. The secure connection ensures EMI resistance and a long service life for the connector.

The 208743-4 D-Sub connector is a reliable, high-performance, and cost-effective choice for many industrial and consumer applications. Its variety of forms and sizes make it an ideal choice for applications requiring low-level and high-frequency signal transmission. Its robust construction and secure connection ensures long-term operation in even the harshest environments.
