The QTH-030-03-L-D-A-K edge connector is part of a range of rectangular connectors designed to meet an array of needs in industrial, commercial, military and other special applications. This particular model is designed for edge and mezzanine types of applications, including board-to-board, wire-to-board, and wire-to-wire connectors. It is constructed using stamped and formed contacts and has a range of contacts configured in a single-row, dual-row, or even triple-row style. This range of contacts allows the user to select the best configuration for their needs.

The name ‘QTH-030-03-L-D-A-K’ represents a number of configuration parameters including the number of rows required (030 for three rows), the number of contacts (03, 003 for three contacts), the contacts’ length (L for Long, which is 1.2mm), the contact’s diameter (D for 0.3mm diameter), and the contact arrangement (A for array). The final option (K) is the contact type, which in this case is Kinked for improved contact retention in high vibration applications.

The connector’s primary application is in board-to-board interconnects, where it offers greater connectivity when compared to other edge or mezzanine connectors. It is commonly used for printed circuit boards, chasses, or backplanes. Its mezzanine design offers a number of advantages, not least of which is the ability to stack multiple boards side by side, creating a more compact design. The connector’s kinked contacts also offer improved retention, providing additional support for the board-to-board connection.

QTH-030-03-L-D-A-K’s mode of operation is relatively simple. The contacts, which are constructed from high-grade plated copper alloy, are fixed to the edge of the board. When the mating board is inserted, the contacts make contact with the mating contacts on the board and an electrical path is established. The connection is held securely in place by a simple clip mechanism, which holds the mating boards together, while allowing them to be easily disconnected if required.

In summary, the QTH-030-03-L-D-A-K connector is an ideal solution for board-level interconnects in the edge and mezzanine application arena. Its triple-row design is suitable for high-density interconnect applications, while its kinked contacts increase its vibration resistance, improving its ability to maintain a reliable connection in harsh environments. With its simple mode of operation and robust contacts, this is an ideal addition to many industrial, commercial, and military electronics applications.
