Rectangular connectors are a popular choice for many electronic and industrial applications, especially for those requiring higher temperature ratings and/or high potential voltages. The ESQT-105-02-M-Q-309 is a type of rectangular connector that has a variety of applications and working principles. It is used in a variety of industries including aerospace, automotive, and telecommunications.

The ESQT-105-02-M-Q-309 is a high temperature, high voltage, and high density connector that supports up to 105 contacts in a single connection. It is based on the MIL-C-24308-1 nominal 12.5mm size with two rows of contacts and a 1.27mm/0.050” x 2.54mm/10.16” spacing between contacts.

The ESQT-105-02-M-Q-309 is a right Angle PCB Mount (RA) header and receptacle that can be configured with options to accommodate an array of industry requirements. It is designed to mate with compliant RA receptacles from numerous partner companies. Its right angle design enables the user to mount the connector at angles closer to the PCB surface and optimize PCB space. The ESQT-105-02-M-Q-309 is rated for temperatures from -55°C to +125°C and its unique design provides high contact retention force with low insertion and extraction efforts.

The ESQT-105-02-M-Q-309 uses a box header-type contact typically manufactured from brass and plated with gold or tin. The design of the connector includes self-aligning male and female cavities that match the pins on both the box and receptacle. The self-aligning mechanism ensures that the connector mates accurately even with misalignments. The connector has a locking mechanism that ensures the connector mates securely.

The working principle of the ESQT-105-02-M-Q-309 is relatively simple. The contact spring in the header provides high contact forces when it is inserted into the receptacle, resulting in high contact performance and reliability. There is also a closed side shield that provides a low-reflection environment, and the shielding element makes sure that all electromagnetic interference is kept inside the connector. The connector uses a blind mating system that allows the connections to be made without being visible, resulting in a clean design.

The ESQT-105-02-M-Q-309 is a versatile connector suitable for various types of industrial applications. It can be used for both in-cabinet and board-to-board interconnects, as well as feed-throughs. Its right angle design makes it suitable for a variety of application topologies and enables it to be used in tight spaces. The wide range of mating options gives users flexibility in selecting the appropriate connector for their application. In addition, the unique design of the contact spring provides high contact forces, resulting in superior signal integrity and reliability. The closed side shield also contributes to low EMI emissions. The ESQT-105-02-M-Q-309 is an excellent choice for any demanding application where superior signal integrity and reliable connectivity are required.
