7-2110400-3

7-2110400-3 is one type of rectangular connector, which is often used in arrays, edge type, and mezzanine (board to board) applications. This type of connector offers a high pin density and for robustness and durability, and allows engineers to make designs in many different configurations, including single and double row versions and mixed density wiring schemes.

The 7-2110400-3 connector comes with an array of gold-plated pins arranged in two arrays, one which is set in the center of the connector and the other which runs along the edges. This provides much higher pin density than with other connectors, making the 7-2110400-3 a popular choice when space is limited. The pins are spaced 1.27mm apart and feature a nominal contact force to ensure reliable connections. In addition, the connector is also designed with embedded actuators, which enable signal transfer between two boards without additional mechanical means. This feature is highly advantageous for system reliability and assembly time.

The working principle of the 7-2110400-3 consists of two components. First is the pin locking mechanism, which is activated when plugging in the connector. The pin locking mechanism is designed to prevent the connector from accidentally disconnecting. Second is the contact force spring. This spring is located between the two arrays of contact pins and applies a consistent pressure on each pin individually. This ensures reliable connections as it prevents contact pins from bending or wobbling during operation.

In terms of applications, the 7-2110400-3 can be used in arrays, edge type, and mezzanine (board to board) designs. It is commonly used in PCBs with high-density layouts, including data storage devices, communication equipment, and industrial controllers. Its small size and pin density make it a great option for these types of products. For edge type applications, the connector can be used for electric vehicles, home automation, and LED lighting. Lastly, for mezzanine (board-to-board) applications, the connector is suitable for boards in medical and digital camera systems, and can be used for transmitting data, power, and even heat.

In conclusion, the 7-2110400-3 rectangular connector is a great choice for arrays, edge type, and mezzanine applications due to its high pin density and pin locking mechanism. It provides robust connections and is designed to be reliable in the toughest environments. The connector is also suited for a wide range of applications, including data storage, communication equipment, medical devices, and LED lighting.
