QMS-104-05.75-L-D-RF2 Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) Application Field and Working Principle

QMS-104-05.75-L-D-RF2 is a high-performance rectangular board-to-board connector from the corporation, designed for implementation in mission-critical, high-speed systems where design optimization and space constraints are of the essence. It falls under the category of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) connectors, and is aimed to provide a reliable, robust connection between two PCBs or between a PCB and a backplane.

This edge-connector system offers high performance, enhanced data rate, and is optimized for a wide range of applications, from industrial, consumer to automotive, where signal integrity and high-speed transmission with lowest possible cross talk between differential lines need to be taken into account.

The connector is constructed of four different parts – the plastic housing, which features a glass-filled PPS assembly that provides high-density and in-service functionality with superior retention force and easy assembly of the board-to-board connection, the male and female contacts which provide high-speed, high-density signal wire-to-board connection, and the metalized shield that prevents electromagnetic interference.

The board-to-board design features two arrays of five pins each, making the overall number of contacts effective 10, with 5 differential pairs each of which further supplemented by a ground connection, so that total number of physical connections in the mated stack reaches up to 12. The high-speed differential lines are arranged in offset rows, and the distance between them is 0.5mm, boasting improved robustness and enhanced electrical performance in high-speed operation.

The QMS-104-05.75-L-D-RF2 connector is very easy to use, and utilizes a latch locking system which is easy to assemble and intuitive to use. The boards press together until the latch clicks, registering the connection and providing a reliable electrical connection as well as mechanical strength. This eliminates the need for dust covers or other protection.

The QMS-104-05.75-L-D-RF2 connector boasts a support of up to 1.3A operating current and VDD=5V, making it suitable for most digital applications with 4GHz frequency range. It is also rated to withstand up to 5G vibrations of axial force, providing excellent and reliable performance in highly stressful and rugged environments.

Colour-coding of the pins and the receptacles makes the connector intuitively easy to use, and the QMS-104-05.75-L-D-RF2 connector is designed to withstand the harsh conditions and handle the EMI and vibration issues that might arise in a wide range of applications.
