Introduction

QFS-026-01-L-D-RA-K is a rectangular connector - array, edge type, mezzanine (board to board). It is an integrated, multi-purpose assembly that offers a broad range of electronic interfaces, allowing for the interconnection of two or more mezzanine boards. QFS-026-01-L-D-RA-K is designed for use in a variety of high-speed, high-density applications that require smaller amounts of data exchange.

Application Field

QFS-026-01-L-D-RA-K connectors offer an array of features, making them well-suited for a variety of applications. They are low-profile, space-optimized, mechanically secure, and have a mechanically robust and reliable interface. The connectors allow for high-speed, high-density data transfer, making them well-suited for a wide range of applications such as industrial control, consumer electronics, and automotive. Due to their small, low-profile size, QFS-026-01-L-D-RA-K connectors are also suitable for miniaturized applications requiring up to 14 front-panel contacts.

Working Principle

QFS-026-01-L-D-RA-K connectors employ a cellular matrix array of contact pins, which is able to provide a consistent electrical performance over many insertion cycles. The connectors are designed to be mated together via a mechanical snap-in locking mechanism. Each connector contains two pairs of polarization keys and a retaining key to prevent mismating. The polarization keys only allow the connector to be mated in the correct orientation. The terminals of the QFS-026-01-L-D-RA-K connectors are composed of a gas-tight and durable copper alloy. The contact surfaces are plated with gold, nickel, or tin over palladium, providing superior electrical performance and enhanced durability. The connector shells are UL94V-0 rated and are designed to secure against EMI leakage.

Conclusion

QFS-026-01-L-D-RA-K connectors are dependable, high-performance connectors that are ideal for a variety of mezzanine board-to-board applications. With their low-profile, space-optimized design, superior electrical performance, and secure mechanical interface, these connectors are well-suited for the high-speed, high-density data transfer requirements of today’s industrial, automotive, and consumer electronics devices.
