Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQT-112-03-L-D-374 is a rectangular connector, designed for the purpose of making fast and efficient connections between lines, be it either for power, control, ground, data signals or a combination of these.

Application Field

The ESQT-112-03-L-D-374 is mainly used as a connector in communications and interconnect systems for various industrial applications. Such applications include computer networks, data centers, medical systems, military systems, aerospace applications, automotive assemblies, and much more.

The ESQT-112-03-L-D-374’s design allows it to be used reliably in a wide range of temperatures, starting from -20°C and reaching up to +105°C, and even exceeding those temperatures with a temperature range of -20 up to +150°C. This makes it especially suited for usage in outdoor applications and harsh environments.

Working Principle

The working principle of the ESQT-112-03-L-D-374 connector revolves around its design and construction. The main body, or insulator, of the connector consists of high-temperature thermoplastic material, making up the walls and frame of the unit. The walls and frame act like an enclosure for a number of pins which are inserted into it and then locked in place, by means of a screw.

The inserted pins are then surrounded by a shield, usually made of metal, which serves to protect the pin from external influences and ensure the reliable transfer of signals. The shield is then covered with a metal casing, again for the purpose of protecting the connection from mechanical damage and dirt. Lastly, the metal casing is positioned in a metal sleeve, which serves for the purpose of fixing the connection in place.

The combination of all these elements ensures a reliable transfer of signals with minimum losses, since all the parts fit snugly together, increasing the consistency of signal and power quality even at high level of frequency.
