Rectangular Connectors – Headers, Receptacles, Female Sockets are very versatile, being used in a range of industries to provide high-speed connections between components. One of the most common types of rectangular connectors is the ESQT-122-03-F-D-389 connector. In this article we will explore the application of this type of connector and its working principle.

Application

The ESQT-122-03-F-D-389 is three-row rectangular connector used in high-speed interconnections. It is designed to provide reliable, shielded connections in applications such as industrial control systems, medical equipment, automotive electronics, robotics and more. It can also be used in telecommunications, aerospace and military applications, due to its robust and durable design. The advantages of using this type of connector include its high contact mating reliability, low contact resistance, and resistance to temperature, vibration and shock.

The ESQT-122-03-F-D-389 has an operating voltage of 250V AC/DC and an insulation resistance of 1000 MΩ, making it suitable for a range of applications. It is capable of transmitting power and data signals, and is backward compatible with other rectangular connectors in its range, offering users a greater level of flexibility when connecting components. It is also designed to enable customization, with an array of different contact configurations and colors available.

Working Principle

The ESQT-122-03-F-D-389 connector utilizes a plug-and-play connection mechanism. It consists of two connector halves, the receptacle (host) and the plug (source). They both feature three female and three male contact pins which make contact when the two halves are connected. The contact pins are precision manufactured using highly durable and resilient materials, such as brass and copper alloys. They are designed to ensure a secure connection, providing a tight contact grip between the pins.

The connector is designed to be easy to use and provides a secure connection undergoing repeated mating cycles. It is important to ensure that the contact pins are clean and free of debris to ensure the best connection. The connection can be terminated after use by pulling the connector halves apart manually, or it can be released using a special latch mechanism.

In addition to providing a secure connection, the connector is also designed to protect against electromagnetic interference (EMI) and radio frequency interference (RFI). The contact pins are specially designed to minimize signal loss and crosstalk due to EMI and RFI, ensuring a reliable signal transmission. The connector is also designed with EMI suppression devices, such as ferrites, and shielded by an internal metal shell to further improve EMI protection.

Conclusion

The ESQT-122-03-F-D-389 is a versatile, reliable and high-performance connector providing robust connections between components. Its plug-and-play design makes it easy to use and its specialized contact pins and EMI protection features make it suitable for a range of applications, including automated systems, industrial control systems, medical equipment, automotive electronics and more. It is also compatible with other rectangular connectors making it a flexible and customizable solution for application designers.
