The ESQT-125-02-G-D-705 is a type of rectangular connector that is specifically designed to meet the needs of medical, avionic, and military industries. This type of connector is seen as a robust way of making a connection since it is made with a higher level of durability in mind.

The name and technical parameters of this connector make it easier to identify and differentiate it from other connectors. Specifically, its ESQT designation means that the connector fits into the ESQT range of rectangular connectors. Additionally, the 125-02-G-D designation of this connector matches with the details that PinMei Electronics lists on its website. As such, this particular connector has an overall width of 125 mm (4.92 in) and consists of two columns, with each column having two rows of contacts.

Additionally, the ‘7.05’ at the end of the designation represents the environmental sealing rating of this connector. It was tested in accordance with NF EN 60529, which is a common standard for measuring the degree of protection from solid and liquid objects. As per point 9.5.2 of the standard, this particular connector has an environmental sealing rating of IP67.

This connector features two headers, one receptacle, and one female socket. While headers are typically used to connect signal wires between two printed circuit boards (PCBs) and are not typically robust enough for high vibration levels, their design and build allow them to be used in conditions where a large amount of vibration might be introduced into the system. Receptacles, on the other hand, are designed to hold plug-in devices such as audio-visual equipment, cameras, and data connections, and usually require a robust connection in order to withstand high vibration levels and/or accidental damage.

Finally, female sockets are typically used to attach the connector to the chassis of a device. They are designed to be robust enough to withstand the effects of shock and vibration in the field, yet are flexible enough to mount easily to the chassis. This is achieved by offering a variety of different mounting styles, such as either conductive or non-conductive, along with a variety of different options in terms of cable dress. These mounting styles coupled with the durable build of the connector allow it to be used in a range of environments, from the toughest marine applications to the gentlest laboratory environment.

In terms of working principles, this type of connector primarily uses a combination of conductive pins housed in a plastic insulator to create an electrical connection. The pins are inserted into a receptacle and the connecting pins of the mating device are then inserted into the header holes. This creates an electrical connection, and the connector is held firmly in place by the friction between the pins and the insulator. Additionally, this connector is made of a conductive material and offers several features such as heat dissipation, environmental protection, and vibration resistance which make it suitable for a wide range of applications.

In conclusion, the ESQT-125-02-G-D-705 is a type of rectangular connector specifically designed for industrial use. It is robust enough to withstand high levels of vibration and shock, yet flexible enough to allow for a variety of mounting options. Additionally, its environmental sealing rating of IP67 makes it suitable for a variety of applications where a higher level of durability and reliability is needed. Finally, the working principle of this type of connector involves the insertion of conductive pins into a receptacle, creating an electrical connection.
