Introduction

The ESQT-111-03-G-D-320 is a type of rectangular connector from the headers, receptacles, and female sockets family. Like most rectangular connectors, this unique component is designed for providing secure, reliable connections between circuits in electrical systems and devices. In this article, we will discuss the ESQT-111-03-G-D-320’s application field and its working principle.

Application Field

The ESQT-111-03-G-D-320 is typically used in applications such as computer and communication equipment, medical appliances, automobile systems, industrial electronics, security systems, etc. It is designed to be reliable even in the most demanding applications such as under high vibration, frequent operation, exposure to harsh environments, and much more. This connector is also cost-effective and easy to install, which makes it an ideal choice for many different applications.

Working Principle

The ESQT-111-03-G-D-320 is a three-pin connector rated for 250V rated voltage, 10A rated current, and 500V insulation voltage. It can handle up to 20W of power dissipation. This connector is also UL rated and is rated according to CSA C22.2 number 8.2. The connector is made from carbon-fiber reinforced plastic and has a standard 0.1” spacing between the pins.The working principle of the ESQT-111-03-G-D-320 connector is simple. When plugged in, the pins make contact with their corresponding pin on the receiving connector. This contact allows an electrical connection to be established between the two pins, allowing the transfer of electrical signals from one circuit to another. The connection is secure and reliable due to the spring action of the pins, which ensures that they remain in contact even during rapid movement or vibration.

Conclusion

The ESQT-111-03-G-D-320 is a rectangular connector from the headers, receptacles, and female sockets family. It is typically used in applications such as computer and communication equipment, medical appliances, automobile systems, etc. It has a three-pin design, is rated for 250V, 10A, and 500V insulation voltage, and can handle up to 20W of power dissipation. Its secure, reliable connection is established between two pins via the spring action of the pins, allowing for electrical signals to be transferred.
