ESQT-145-02-H-S-309 is one of the most popular rectangular connectors within the Headers, Receptacles and Female Sockets category of electronic components and is known for its durable yet reliable performance and efficient design. Essentially, its design consists of two pieces that form a single, rectangular module that can be used in different types of electronic connectors.The most common application of the ESQT-145-02-H-S-309 is for board-to-board connectors, where two separate connectors can be soldered, secured or glued together to create a single, rigid connection. Additionally, another common application is its use as an interface or port for connecting various forms of circuitry and systems.To better understand the ESQT-145-02-H-S-309’s working principle, it is best to imagine it as a series of electrical contacts arranged in rows and columns. The male header side of the connector consists of a series of contacts that are arranged in rows and columns bisecting one another.The female receptacle side of the connector also consists of a series of contacts arranged symmetrically beneath the male contacts. When the male and female pieces are mated together, the contacts form an electrical connection. The connection is made by the pressure driven fit between the two pieces, which is held together by precision machining, ensuring the contacts do not form any air gaps.The ESQT-145-02-H-S- 309 is a rather versatile device, as it can be installed and used in a number of different ways, such as wire-to-wire, wire-to-board, or board-to-board configurations. Additionally, its pins and rows can still be used even when mounted in custom form factor board configurations.The ESQT-145-02-H-S-309 is also known for its durability and reliable performance in different operating environments. Its built-in contact protection is designed to help guard against electrostatic discharge, and the male /female connector is rated for up to 3 Amps of current. Although it is not the most lightweight device on the market, it is suitable for different rugged environments that have exposure to a variety of environmental conditions.Finally, the ESQT-145-02-H-S-309 is also known for its relatively cost-efficient production costs. The device itself is relatively simple to manufacture, plus its lower current rating adds to its cost-effectiveness without compromising its performance. All-in-all, the ESQT-145-02-H-S-309 is an efficient, robust and durable rectangular connector that can serve numerous application scenarios.
