Introduction

The ESQT-128-03-G-S-375 is a rectangular connector that comes in various shapes, sizes, and termination styles. This particular connector is designed for applications where space is limited and is typically used in a wide range of electronic and machine assemblies. As the name suggests, this connector consists of a header, a receptacle, and a female socket.

Header

The header is the stationary part of the connector that mates with the receptacle or female socket. It contains the contact pins that make electrical contact with their counterparts in the receptacle or female socket. The header is made up of two components: an electrically insulated base with mounting hardware, and a metal cover containing the contact pins. The pins may be arranged in various combinations, depending on the number of signals to be transmitted.

Receptacle

The receptacle is the movable part of the connector that mates with the header. It contains contact pins that mate with their counterparts in the header when the receptacle is inserted into the header. The receptacle is usually mounted on the part of the device that needs to be connected to the rest of the system. The receptacle may also contain a hood to protect it from dust and dirt.

Female Socket

The female socket is the other movable part of the connector and is used to connect the system to an external component, such as a computer or a printer. It contains a set of contact pins that mate with their counterparts in the header when the female socket is inserted into the header. The female socket may also contain a hood to protect it from dust and dirt.

Application Field

The ESQT-128-03-G-S-375 connector is designed to be used in a wide range of applications, such as automotive, industrial, and telecommunications. It is most commonly used in applications where space is limited and multiple signals need to be transmitted. Additionally, the connector can be used in applications that require high speed signal transmission and are exposed to harsh environments.

Working Principle

The working principle of the ESQT-128-03-G-S-375 connector is quite simple. When the header is mated with either the receptacle or the female socket, the contact pins in each component make electrical contact with their counterparts in the other component. This allows signals to be transmitted between the two components. The connection is secure and reliable due to the locking mechanism built into the connector.

Conclusion

The ESQT-128-03-G-S-375 is a rectangular connector that is ideal for use in applications where space is limited and multiple signals need to be transmitted. It consists of a header, a receptacle, and a female socket, which are designed to mate with each other securely and reliably. The connector is suitable for a wide range of applications, including automotive, industrial, and telecommunications. It is also capable of high speed signal transmission and is designed to withstand harsh environments.
