Introduction

ESQT-145-02-H-D-309 is a rectangular connector tailored to a variety of applications, and it is classified as a header, receptacle, and female socket. As with all connectors that belong to the same family, the ESQT-145-02-H-D-309 is designed to be used for electrical signal applications. Made from an electrolytic copper alloy, this connector provides excellent electrical and mechanical characteristics.

Application Field

The ESQT-145-02-H-D-309 is suitable for all kinds of industries which require secure electrical connections. It is especially designed to be used in specific industrial applications, such as automotive, telecommunications, industrial, computer, consumer electronics, medical, and aerospace. It works efficiently in digital and analogue signals applications, withstanding temperatures up to 100°C.Finally, its high-frequency rate make the ESQT-145-02-H-D-309 suitable to carry high-frequncy signals as well as DC voltage, which works as a great solution for high-speed connections in the previously mentioned industrial applications.

Working Principle

The typical working mechanism of the ESQT-145-02-H-D-309 female connector includes a connector sleeve with two guide pins, a friction knob, a crimp band, and an insulator sheet. This is the general design applied for rectangular connectors, albeit it is slightly modified for each specific model.The two guide pins ensure that the connector is properly inserted into its female counterpart. The friction knob is activated when the connector is completely inserted and it provides a secure attachment. The crimp band and the insulator sheet are made from a polyatomic material that provides both insulation and secure connection.Usually, the ESQT-145-02-H-D-309 connector is used in combination with a male connector (the opposite type) that is attached directly to the cable\'s conductor. This way, the male connector is linked tightly to the female connector, providing a secure electrical connection.

Conclusion

The ESQT-145-02-H-D-309 is a versatile rectangular connector specification that belongs to the headers, receptacles, and female sockets family. Designed for industrial applications, it is capable of transmitting digital and analog signals, in addition to its ability to handle high-speed data transmissions with its high-frequency rate.Finally, the ESQT-145-02-H-D-309 is specifically designed with a connector sleeve, two guide pins, a friction knob, a crimp band, and an insulator sheet to ensure secure and reliable electrical connections.
