The QSH-120-01-C-D is a rectangular connector array of the edge type, used for mezzanine board-to-board applications. They belong to a family of components known as edge connectors, which are designed to fit the shape of a circuit board\'s edge with their beveled-edge surface, allowing it to make contact with contact areas of the same shape on another card when mated.

This connector is designed with two rows of multi-pin inserts on one side, with multiple arrays on the opposite side. It features industry-standard pitch of 2.00mm, and contacts which are rated up to 10A. Its plastic housing has been UL94V-0 approved, and is available in three shell sizes, although the QSH-120-01-C-D comes as a 120-pin version. Operating temperatures range from -55℃ to 125℃, and it is tested to frequencies up to 8GHz.

The main application field of this connector is programmable logic and mixed-signal boards. With its high pin count and high contact density, this terminal is well suited for high speed board-to-board interconnections, allowing fast interfacing between electronics designs.

The device is designed to make and break connection using two sets of spring contacts. The spring contacts are arranged in duplication on opposite sides of the contact\'s neutral position, in between the two opposing edges of the component. The pins can be inserted and withdrawn from the socket without much force, however when fully inserted, they are also held securely in place against a natural spring action which lightly presses them both inward and outward. Once mated with the contact area on the other board, the two opposing sides form a continuous current pathway. In this way, a basic bridging connection is established, which helps transfer both electrical power and signals between two different boards.

When properly connected, the QSH-120-01-C-D provides a robust and reliable connection. It can be used to support both low and high-speed signals, and offers good shielding between the two boards due to its aluminum plated copper alloy construction. In addition, this connector can also be used in medium-power signals, making it a good choice for a wide variety of electronics applications.

Overall, the QSH-120-01-C-D is a versatile edge connector which is designed to provide reliable connections for mezzanine board-to-board applications. With its high pin count and contact density, this device is able to support both low and high-speed signals, and also offers robust shielding and reliable data transmission.
