The D-Sub Connectors family is one of the oldest and most common connector families around. They are reliable and economical, and they can be used in a wide variety of applications. One such connector is the L77TWC21WA4S connector. This article will cover the application field and working principle of this connector.

A L77TWC21WA4S connector is a double row, low profile, screw-mounted D-Sub Connector with 9 pins. It is primarily used in Ethernet applications due to its low profile and reliable connection. The L77TWC21WA4S can be found in consumer and industrial products such as modems, routers, and industrial control systems. The L77TWC21WA4S connector is also used in audio and video applications, as well as USB and RS-485 applications.

The L77TWC21WA4S connector is made up of two parts: the body and the terminals. The body is made up of a metal shell that houses the terminals, which are usually made of copper. The terminals are connected to the device’s cable via the screwmount feature and a grounding clip. The terminal contacts are then inserted into the body of the connector and the screws are tightened to ensure a secure connection.

The working principle of the L77TWC21WA4S connector is based on the same principles as all D-Sub connectors. It involves the insertion of the connector’s terminals into the connector’s body and the application of a tension force to ensure a secure connection. Once the terminals have been inserted and the force is applied, the pins establish an electrical connection with the device’s cable, allowing data to be transferred between the two. The contact points of the connector also provide reliable long-term contact that helps protect against vibration and corrosion.

In summary, the L77TWC21WA4S connector is a double row, low profile, screw-mounted D-Sub Connector with 9 pins. It is primarily used in Ethernet applications, but can also be found in consumer and industrial products such as modems, routers, and industrial control systems. Its working principle is based on the same principles as all other D-Sub connectors, involving the insertion of the connector’s terminals into its body and the application of a tension force to ensure a secure connection.
