Rectangular Connectors, most commonly referred to as Headers, Receptacles, and Female Sockets, are a range of electrical connectors used mainly in electronic devices. The most common of these are the ESQT-116-02-M-D-689 type of Rectangular Connectors. This type of connector is one of the most commonly used in today’s equipment.

The ESQT-116-02-M-D-689 is a single row type that covers a broad range of electronic devices where space and connection requirements are not extreme. This connector type is usually manufactured in two variants – surface mount (SMD) and through hole (THD). In either version, the design is comprised of four conductor sockets (two columns, two rows) and a small center contact plate to accommodate a single wire connection. The contacts are generally made of tin-plated steel and come with a gold option for increased wear and corrosion resistance.The key feature of the ESQT-116-02-M-D-689 style connector is the use of two gold fingers, which act as separate shields for each row of contacts. This provides additional protection by keeping the contacts in a confined space and minimizing the risk of short circuits.

The ESQT-116-02-M-D-689 is typically used in applications such as low power or signal distribution and conditioning in the form of wires, cables, resistors, transistors, integrated circuits, etc. It is also used in medical, automotive, and aerospace equipment. This connector is suitable for use in harsh environments, such as high-voltage installations, or in high-vibration applications. The connector also boasts a very low contact resistance, making it ideal for use in high-frequency applications.

The working principle of the ESQT-116-02-M-D-689 connector is quite simple. To make a connection, two mating parts are fitted together. Pressure is applied at the mating edges which engages the two gold fingers. When correctly applied, these gold fingers create a hermetic seal, ensuring a secure and reliable connection. The solid state gold contacts provide excellent electrical performance. They are also designed in such a way that they can withstand considerable vibration, providing optimal service in even the most extreme conditions. At the same time, the ESQT-116-02-M-D-689 connectors provide a very low insertion force, ensuring that the contact is securely held and ready for use.

In conclusion, the ESQT-116-02-M-D-689 Rectangular Connector is a robust and reliable solution for making secure electrical connections. It is very easy to use, boasting low contact resistance and a hermetic seal. It provides exceptional electrical performance and very low insertion force. It is ideal for use in a wide range of applications, including high vibration and high voltage installations. The ESQT-116-02-M-D-689 is suitable for use in any environment, making it one of the most versatile and reliable connectors on the market.
