The ESQT-131-03-S-D-380 is a rectangular connector, belonging to the headers, receptacles, and female sockets family. It offers advanced features that can meet the demands of the most complex application requirements. This document aims to cover the application field and working principle of this connector.The ESQT-131-03-S-D-380 is one of the most popular rectangular connectors in the industry, providing both signal transmission and power delivery solutions for a range of applications. It has been widely used in communication equipment, automation devices, medical equipment, and LED lights. It is also used in instrumentation, automotive and office equipment and other electronic equipment.The connector has a two-piece design which allows it to fit into small spaces that traditional rectangular connectors could not fill. The first piece of the connector is a socket, which is inserted into a printed circuit board, providing an interface to the components inside the board. The second piece is a header and this is connected to the wiring harness of the device, providing a connection to the external power source.The working principle of the ESQT-131-03-S-D-380 is fairly simple. When power is applied to the socket, the current flows into the header, which is connected to the wiring harness of the device. The electricity then transfers through the wiring harness to the external power source, providing power to the device.The ESQT-131-03-S-D-380 is also designed to protect against electrostatic discharge, which is when electrical shock is caused by static buildup when operating equipment. To achieve this, the connector features a double-wall insulation, which is designed to protect the components from damage due to static electricity. The connector also features gold-plated contacts to ensure a reliable connection and prevent corrosion.In conclusion, the ESQT-131-03-S-D-380 is a widely used rectangular connector, used primarily in communication equipment, automation devices, medical equipment, and LED lights. It features a two-piece design to fit into small spaces, and has a basic working principle of providing power from an external source to the device. The connector is also designed to protect against electrostatic discharge, and has gold-plated contacts to ensure a reliable connection.
