Background of ESQT-125-02-G-D-776

ESQT-125-02-G-D-776 is a rectangular connector system manufactured by ESQT Connector Company. It is a dual row header assembly and part of the family of female header connector systems. The header connector system is available in a variety of sizes and pitches, so it can be matched to the application\'s needs. The ESQT-125-02-G-D-776 header is commonly used in the electronics and medical industry, as well as a variety of other applications.

Application Field of ESQT-125-02-G-D-776

ESQT-125-02-G-D-776 is specifically designed for space-restricted applications, where a higher density of contacts is required. It is a high-density header system designed to provide an efficient interface. It is commonly used for backplane applications in computers where a high-speed interface is necessary. These connectors are also used extensively in the medical field and in general industrial applications such as metering and sensing.

ESQT-125-02-G-D-776 Working Principle

ESQT-125-02-G-D-776 is a high-density header connector system. The connectors have two rows of contacts, each with a 4mm pitch. The contacts are arranged in two rows and are held in place by high retention force. The connectors are sealed on both ends with unique, patented presses which allow the connector to conform to the application environment and keep the contacts secure. The connectivity of the connectors is achieved by using pull-tracks. These allow for an efficient and secure connection by providing a pull-resistant connection between the two boards.

Conclusion

ESQT-125-02-G-D-776 is a dual-row header connector system and is part of the family of female header connector systems. It is a high-density header system designed for space-restricted applications and is commonly used in the electronics and medical industry, as well as a variety of other applications. The contacts are arranged in two rows and are held in place by high retention force. The connectivity of the connector is achieved by using pull-tracks which provide a secure connection between the two boards.
