Rectangular Connectors - Headers, Receptacles, Female Sockets are important components in various electronic systems, providing electrical connections between circuits and wiring. The ESQT-127-02-FM-S-309 is an example of a rectangular connector used in high-speed applications. This article will discuss the application field and working principle of the connector.

Application Field

The ESQT-127-02-FM-S-309 is a type of board-to-board connector that is used in high speed applications. It is designed for use in a variety of industries, such as medical, automotive, imaging, networking and communication. These connectors feature a 2 mm pitch, dual-row arrangement, with a total of 128 contacts. The contacts are gold plated, which helps increase the connection reliability and conductivity of the connector. Additionally, the connectors are designed to be pluggable, allowing quick and easy connection and disconnection.

Working Principle

The ESQT-127-02-FM-S-309 utilizes a contact technology called Edge-Wise®. This technology utilizes individual spring probes that are designed to penetrate the board by 1-2 mm and establish a reliable connection with the board’s traces. The probes make contact with the board’s traces via a compression spring inserted into each contact. This spring ensures that electrical current can flow easily and evenly from the connector to the board.

The contact interface of the connector is formed by separate horizontally-aligned contact fingers. The fingers are designed to provide a surface area for mating contact and have contact surfaces made from a single metal material. This contact surface greatly reduces the chance of deformation or damage, and contributes to a more reliable connection.

Conclusion

The ESQT-127-02-FM-S-309 is a high speed board-to-board rectangular connector designed for use in a variety of industries. It utilizes an Edge-Wise® contact technology that is reliable and efficient. Additionally, the contact interface of this connector is designed to provide a large surface area for mating contact and have contact surfaces made from a single metal material. This ensures a reliable connection and helps to minimize any possible damage or deformation.
