QFS-052-02-S-D-RA-PC4

Introduction

QFS-052-02-S-D-RA-PC4 is a rectangular connector array, edge type, mezzanine (or board-to-board) conenctor. It has 4 single row of 2x2.50mm sq. shrouded contacts which are suitable for computer applications.

Application Field

QFS-052-02-S-D-RA-PC4 is typically used in embedded and computer applications. It particular, it is very useful in situations where a thin profile is needed, such as 1U rack-mount applications. It is also suitable for the harsh environment found in industrial computing, networking and automation, especially in areas which require tight space constraints.

Working Principle

QFS-052-02-S-D-RA-PC4 works on a simple principle; the contacts that make up the connector are inserted into mating slots on the board, otherwise called pins. These pins and protrusions make contact when a mating force is applied. The four-row, shrouded design of the QFS-052-02-S-D-RA-PC4 allows for a better distribution of impedance across the pins and provides EMI shielding for improved performance.

Connector Design

The QFS-052-02-S-D-RA-PC4 has a molded-in retention feature on the header with four rows of contacts inside of two push-in slots. Each contact consists of two signal terminals. The contacts are surrounded by a thin wall plastic shroud that helps secure the connector in place and prevent it from coming loose. Furthermore, they are designed into a two-piece housing which helps to reduce crosstalk and provides protection against electromagnetic interference (EMI).

Advantages

QFS-052-02-S-D-RA-PC4 offers many advantages, including:

• High reliability and durability
• Low height profile
• Four rows of contacts provide better contact distribution
• EMI protection
• Molded-in retention feature
• Tin plated for superior solderability

Conclusion

In conclusion, the QFS-052-02-S-D-RA-PC4 is a reliable, durable, and low-height profile rectangular connector array, edge type, mezzanine connector. It offers EMI protection, high contact reliability and a molded-in housing retention feature for enhanced performance and reliability. It is suitable for use in harsh environment, such as industrial computer, networking and automation, and is also suitable for 1U racking application.
