Rectangular Connectors, more commonly referred to as Headers, Receptacles, and Female Sockets, are commonly used in a wide array of electronics and systems. While each type of rectangular connector has its own nuances in terms of material type, size, form factor, and other unique features, a detailed focus on the ESW-112-39-G-S-LL (hereafter referred to as ESW-112) will be used to identify the common application field and working principles of rectangular connectors.

At a basic level, ESW-112 is used to connect two different electronic components to one another via a physical, mechanical connection. The ESW-112 can be broken down into three major sections: the header, the receptacle, and the female socket. The header is the male end of the connection, made up of two components: the pin and the receptacle. The pin is a round metal rod, typically made from copper, that is inserted into the larger receptacle portion and held into place by a metal spring.

The receptacle is the female end of the connection, made up of two components: the receptacle housing and the female socket. The receptacle housing is typically made of plastic and accepts the head of the pin. The female socket is inserted into the receptacle housing and contains a series of pin terminals that mate with the metal contacts of the pin. The female socket is typically made from insulation-dispersion material, such as picoflex or various polymers, to ensure that an electrical connection is maintained between the two terminals.

In terms of applications, the ESW-112 is most often used to connect equipment cabinets, computers, and industrial control systems. The connection is typically established via a standard 3.5mm or 5.5mm connector. The higher-end models may also feature a locking mechanism to ensure that the connection is properly made. When the connection is established, the metal contacts of the pin will make contact with the female socket, creating an electrical connection.

In terms of operation, the ESW-112 is an electrically isolated connection, meaning that there is no direct current (DC) travelling between the two components. The connection is established via the signal voltage, which is then applied to a coil that is located within the receptacle housing. When the coil receives the signal voltage, it causes the pin to be pulled into the receptacle, creating an electrical connection between the two components.

The ESW-112 is also capable of providing power to the connected components. In this scenario, a power cord is attached to the back of the header and plugged into an AC outlet. When the power cord is plugged in, the signal voltage will travel through the power cord and into the coil, causing the pin to be pulled into the receptacle, thus providing power to the components connected via the ESW-112.

In summary, the ESW-112 is a rectangular connector that is commonly used to connect two electronic components, such as equipment cabinets, computers, and industrial control systems. The connection is made via a standard 3.5mm or 5.5mm connector, with the higher-end models featuring a locking mechanism for added security. The connection is established through an electrically isolated connection with the pin being pulled into the receptacle via the application of a signal voltage. The ESW-112 is also capable of providing power to connected components, making it an ideal solution for a variety of electronic system applications.
