ESQT-143-02-H-Q-309 Rectangular Connectors - Headers, Receptacles, Female Sockets

ESQT-143-02-H-Q-309 rectangular connectors are a type of power connector and are classified within the Headers, Receptacles, Female Sockets group. These specialized connectors are designed to be resistant to a wide range of environmental factors and vibration levels. ESQT-143-02-H-Q-309 rectangular connectors are designed for applications such as industrial control, robotics, and communications in more demanding environments. Operating temperatures are usually in the range of -25ºC to +85ºC to prevent premature failure due to extreme temperature cycling. In addition, they can also be used in more sensitive applications, such as medical and aerospace, where vibration and shock protection are required. The connectors in this category use a multi-pin design to provide power and signal connections safely and reliably in high-density circuits. They feature a robust housing design, which allows multiple components to be connected in close proximity, providing greater design flexibility and cost savings. Some examples of connectors found in this family are the ESQT-143-02-H-Q-309 and the ESQT-141-17-H-H-601. The components in the ESQT-143-02-H-Q-309 family are available in various sizes, from a 4-pin to a 64-pin configuration. They are typically available in both through-hole and surface-mount versions, as well as in various current ratings. The contact retention force is also designed to meet the requirements of the application and address complicated mating issues. The single or multi-row design options allow for a more flexible layout of the printed wiring boards, another advantage of these connectors. In addition, ESQT-143-02-H-Q-309 rectangular connectors have a wide selection of contact types including manufactured (stamped-and-formed), machined (bent), and press fit contacts. These contact options provide design engineers with the flexibility to create a connector suited to the specific needs of their application. The contacts are designed to provide secure electrical and mechanical connections without compromising on performance. The working principle of ESQT-143-02-H-Q-309 rectangular connectors revolves around the mating of the pin and socket contacts. The pressure bar contacts are pierced in order to form the contact between the male and female connector. This ensures a reliable and secure connection. The pressure bar contacts also provide high current carrying capacity and have low contact resistance. Once the pin and socket contacts have been mated, they can be un-mated easily and safely. ESQT-143-02-H-Q-309 rectangular connectors are designed for a variety of applications in demanding environments, offering high-performance and reliability. Their robust design, contact types, and wide range of configurations make them a great choice for many applications. With a variety of features and a wide selection of contact types and current ratings, these connectors are suitable for a wide variety of applications.
