Application Field and Working Principle of ESQT-145-02-S-Q-309 Rectangular Connectors

Rectangular Connectors, also known as edge connectors, are an essential component of electronic techniques and found in many devices such as computers, automotive, medical, and communication. They are mainly made from plastic and have two opposite side metals for making electrical connections between devices.The ESQT-145-02-S-Q-309 is a specialized rectangular connector of the headers, receptacles, female sockets family. This particular connector allows making connections between two devices without cables, or using cables to extend the connection. It consists of a female socket and a header side. Depending on the application, one or two receptacles can be connected to the female socket. The header side of the connector is generally soldered to the printed circuit board of the device. The ESQT-145-02-S-Q-309 can be used in a wide variety of applications. It is typically found in electronic devices such as home appliances, consumer electronics, communication devices, automotive components, healthcare products, and industrial automation products.The ESQT-145-02-S-Q-309 is designed for reliable use in harsh environmental conditions. The connector is IPx6 rated, which means it is dust-tight and also waterproof. It is also resistant to extreme temperatures and vibrations. The female socket can be securely locked while the male header is made of tough polycarbonate material which can withstand high temperatures without any damage.The working principle of the ESQT-145-02-S-Q-309 is quite simple. A gap between the male and the female contacts allow electrical connection. When the male header is connected to the female socket, the contact fingers make contact and form a connection. The contact length and depth determines the contact force so that the connection is strong and secure.The ESQT-145-02-S-Q-309 is designed to an international standard that offers great scalability and flexibility. The standardized connector size and pitch allows users to interchange components easily. It complies with ROHS and REACH standards and provides millions of connection cycles for a reliable connection. Furthermore, this connector is highly reliable and provides superior conductivity and insulation for long-term use.The ESQT-145-02-S-Q-309 is a versatile and reliable rectangular connector that enables easy connection of two devices and is widely used in various fields. It is designed to provide high reliability and excellent performance in the most demanding environments.
