QMS-026-05.75-L-D-RF1-TR is a type of rectangular connector that belongs to the Arrays, Edge Type, Mezzanine category. It is designed primarily to be used in interconnecting two printed circuit boards (PCBs) in many different applications. The main feature of this type of connector is that it is low profile, allowing boards to be tightly integrated and maximising space.

Design and Construction

The design of the QMS-026-05.75-L-D-RF1-TR is a combination of both robust and lightweight materials, such as a housing made of aluminium alloy and gold plated copper alloy contact fingers, to ensure the highest levels of efficiency and performance. This results in a robust and durable connection, which is designed to withstand a wide range of vibration and mechanical shock.

The housing contains one row of 26 contacts to provide both power and signal connection, along with a board retention device to ensure the two boards are securely fastened together. The contact fingers have a current rating of 1.5 Amps and a voltage rating of 30 VRMS, allowing them to suit a range of applications and provide reliable yet flexible board interconnection.

Performance Characteristics

The QMS-026-05.75-L-D-RF1-TR is designed to offer reliable high-speed performance, which ensures that boards are securely connected with minimal signal interference. The contact fingers provide low insertion and withdrawal forces and come with a 0.5 mm contact pitch for optimal signal density.

This connector is also designed to meet the reliability and durability requirements of MIL-STD-202F. The contacts are designed to up to 3000 mating cycles, with an operating temperature range of -55°C to 125°C. The gold plating makes the connector resistant to corrosion, making it the perfect solution for harsh and extreme environments.

Application

The QMS-026-05.75-L-D-RF1-TR edge type connector is designed specifically to be used in a range of applications that require a high-speed, reliable and durable connection between two PCBs. It is well-suited to industrial, power, automotive, aerospace and medical applications, and is a great choice for a range of printed circuit board interconnection needs.

Working Principle

The QMS-026-05.75-L-D-RF1-TR connector works by having one board, with the male contacts, inserted into the female contacts on the other board. The contact fingers then fit through the contact openings and make contact with both printed circuit boards providing both power and signal connection.

The board retention device, which is integrated into the housing, then holds the boards securely in place, providing a reliable and durable connection. The use of gold plating on the contact fingers ensures that the contacts will remain corrosion free and reliable during the operating life of the connector.
