Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQT-120-02-F-D-430 connectors are among the most popular rectangular connectors for a variety of electronic applications. These connectors provide reliable and cost-effective connection solutions in many industries, including aviation, automotive, medical, military, and telecom. Understanding the application field and working principle of these connectors can make it easier to select the right ones for different needs.

Application Field

The ESQT-120-02-F-D-430 connectors are most often used in applications where electrical connections must be made and held securely. This could be in electrical systems such as fuel injection, engine management, airbag control, and alternator control systems; high-end telecom and LAN applications; aerospace and medical equipment; and power supply systems. These connectors are also used in applications where vibration, shock, and high temperature can occur – such as machine tools, robotic and packaging equipment, air conditioners, and other machinery.

The unique design of these connectors provides maximum flexibility, allowing for the use of four- and five-conductor wires. These include standard round wires, as well as flat and multi-conductor shielded wires for communication. The wide range of materials makes it possible to design connectors for a variety of applications, such as power lines and automotive applications.

Working Principle

The ESQT-120-02-F-D-430 connectors have two separate parts – the header and receptacle. The header is the male connector, which carries the power signal and data. The receptacle is the female connector which connects the header with other components. The two parts lock together using a locking mechanism, such as a thumb screw, snap, latch, or twist lock. The header is typically designed to fit into a specific receptacle, and is designed to be removable.

The connector also features built-in circuitry, which includes a serration skirt, contact springs, metal plates, and a crimp collar. The skirt ensures the contacts stay in the correct position, while the contact springs serve as the connection between the contacts. The metal plates are the electrical connections, and the crimp collar holds the connector in place. It is also designed to hold the connector in the desired location.

Once the connection is made, the contacts on the connector make an electrical circuit. This allows for power signals to be transmitted and received, and data to be sent and received. The connector is designed to remain secure after the connection is made, allowing for secure and long-lasting communication between two components. The flexibility of the design also allows for multiple connections to be made, giving multiple devices the same type of communication.

Conclusion

The ESQT-120-02-F-D-430 is an extremely versatile and reliable type of rectangular connector. Its wide application field makes it ideal for many different types of electronic and telecom applications. Additionally, its built-in circuitry and secure locking mechanism allow for reliable communication between two components. With its flexible design, the ESQT-120-02-F-D-430 connector can be used in many different applications where reliable connections are required.
