Edge type mezzanine connectors are designed to make the connection between two boards or components in an electronic device. These connectors have evolved over time, as higher numbers of terminals and contacts have been designed for more intricate circuits and better performance. The QMS-052-05.75-L-D-RF1 rectangular connector is an example of an edge type mezzanine connector, and is suitable for a broad range of applications.

Application Field

The QMS-052-05.75-L-D-RF1 is a response to a market demand for increased contact density and higher reliability. Designed for applications in LED displays, automotive, medical, aviation, and other industrial and professional applications, the edge type mezzanine connectors has a 5.75mm centerline spacing and 52 terminals. The robust construction of this connector allows it to meet the stringent requirements in these developed applications. It is capable of withstanding temperatures ranging from -55°C to 125°C, and has a rated current of 1A per contact.

Working Principle

The basic design of the edge type mezzanine connector consists of two connector halves. The mating half of the connector is usually mounted to the edge of the PCB, while the other half is connected to a cable. Each connector half has an array of terminals which, when the two halves are mated, interlock to make electrical connection between the two boards. The terminals are then soldered, or crimped, or otherwise secured in place to complete the connection. This type of connector is most commonly used in two board applications, as it provides a secure interconnect solution with relatively low profile.

Features & Benefits

The QMS-052-05.75-L-D-RF1 is a compact connector, designed to provide a secure connection for a plethora of applications. The connector has numerous features and design advantages, including:

• Low profile: due to the internal design, the overall height of the connector is lowered to provide a more compact design.
• Contact retention: ensures secure contact connection and ensures reliable operation.
• Terminal to terminal spacing: the terminals are spaced to provide increased current carrying capabilities.
• Mating retention: once mated, the connectors ensure secure retention, while still allowing for easy unmating.
• Rugged constructions: the contacts and shells are designed for increased robustness, making them suitable for harsh environments.

Conclusion

The QMS-052-05.75-L-D-RF1 edge type mezzanine connector is a robust and reliable solution for applications in LED displays, automotive, medical, aviation, and other industrial and professional applications. Its low profile, contact retention, molded insert, terminal to terminal spacing, and other features provide reliability and security. In addition, its rugged construction ensures that it can withstand temperatures ranging from -55°C to 125°C and has a rated current of 1A per contact, making this connector suitable for a variety of applications.
