QMS-026-05.75-H-D-RF1-TR Rectangular Connectors – Arrays, Edge Type, Mezzanine (Board to Board)

QMS-026-05.75-H-D-RF1-TR rectangular connectors, belonging to the group of arrays, edge type, mezzanine (board to board) connectors, are specifically designed for high speed data transmission applications. They can be used as board-to board or card-to-board connectors, offering multiple contacts, multiple rows, and signals for high-speed multi-lane data rates up to 20Gbps from different sides.

Application Field

QMS-026-05.75-H-D-RF1-TR rectangular connectors are mainly used in industrial, medical, automotive, avionics and telecommunication applications, such as 5G cellular infrastructure, enterprise wireless LAN, Wi-fi 802.11, Ethernet, USB3.1, and LVDS. They are also commonly used in board-to-board, mezzanine, and motherboard applications requiring signal and power transfer in tight spaces thanks to their high density and higher number of contact positions.

Design & Construction

QMS-026-05.75-H-D-RF1-TR are available in the SMT ‘C’ type with a total of 26 rows, with a pitch of 0.75 mm and a maximum height of 5.75 mm, featuring a horizontal format with double-sided contacts. These connectors are constructed with an insulating base so will require a mounting hole in the PCB for each contact, and separate mounting holes for the positioning mount. The double-sided contacts are designed with a tear-drop shaped contact feature to ensure reliable mating and low contact resistance.

Electrical Performance

QMS-026-05.75-H-D-RF1-TR are designed for high-speed data transmission applications, with a maximum interface speed of 20Gbps, and contact resistance of 0.3mΩ max. The rated current is 1Amp, with a recommended insertion and withdrawal force of 9.8N and 2N respectively, welding current of 0.4Amp, and operating temperature range of -40 to +85℃.

Other Features

QMS-026-05.75-H-D-RF1-TR offer a high level of performance and reliability to ensure successful operation in even the harshest environment. This includes shielding features to ensure EMI protection, coupled with low insertion and withdrawal forces which provide for easy docking and undocking. The connectors are designed with anti-mismating features to ensure the correct mating of the connector to the mating components. Additionally they are lead-free components, and feature phosphor bronze contacts with gold plating for good conductivity and corrosion resistance.

Conclusion

QMS-026-05.75-H-D-RF1-TR are a perfect choice for a wide range of industrial, medical, automotive, avionics and telecommunication applications. The reliable performance, high speed data transmission, good conductivity and corrosion resistance make these connectors an ideal choice for tight spaces and harsh environments.
