ESQT-106-02-G-S-450 Application Field and Working Principle

Rectangular connectors, also known as headers, receptacles, and female sockets, are among the most popular graphic connectors ever invented. ESQT-106-02-G-S-450 is one of such products, which has found its application in many areas, from consumer electronics to industrial machinery. This article will summarise some of its features, applications, and working principle.

Features

ESQT-106-02-G-S-450 belongs to the ESQT series of electrical connectors manufactured by NKK. It has a size of 10.6 mm x 2 mm, and a guaranteed retention force of 450N. The body material is brass, while for the contacts, both phosphor bronze and stainless steel are available. Contact finishes include normal, high-temperature, and gold-plating, while its insulation is polyamide. Furthermore, the current rating is 5A and voltage rating is 125V.

Applications

This type of connector is used in a wide range of fields, from automotive to communication systems. Due to its simple and compact design, it is often used in equipment with limited space, such as laptops, tablets, and mobile phones. It is also an economical solution for industrial automation, particularly in applications where plugging and unplugging connectors is frequently needed. Electrical signals can quickly be transmitted with this type of connector, making it suitable for digital onboard networks and CAN buses.

Working Principle

An electrical connection is established when two connectors are inserted and pressed together. This is accomplished by two contact springs inside the connectors which form a mechanical and electrical bond. As one connector slides into the other, the contact spring expands outward and creates an electrical connection between the two connectors. When the connectors are removed, the contact springs return to their original shape, thus breaking the electrical connection.

Conclusion

ESQT-106-02-G-S-450 has found its applications in many different areas due to its versatile features, affordability, and easy connection capability. By understanding its working principle, we can better identify its use cases and make the most of its simple and compact design.
