Introduction

QMS-052-01-S-D-RA-PC4-K is a rectangular connector array edge type mezzanine (board to board). Mezzanine connectors provide a small form factor for interconnecting boards. These high-density connectors are cost effective, reliable, and have a wide range of applications.

Application Field

QMS-052-01-S-D-RA-PC4-K rectangular connectors are widely used in embedded products, communications, medical, instrumentation, and industrial control applications. They can be used as board-to-board or board-to-cable connections. They offer an efficient way of providing reliable and cost effective connections.

Design Features

QMS-052-01-S-D-RA-PC4-K connectors have a 2 x 50 position array that is ideal for higher density in applications. It has a low profile guaranteeing minimum space, and a wealth of design options including both straight and right angled versions, various stack heights, and JEDEC 2.0, 2.1, 3.0, 3.1, 4.2 profiles as well as custom profiles. The contact housings feature molded-in locking portion, with the contact position assurance (CPA) feature ensuring that the contact can only be inserted when mated correctly. The dual-leaf conduit contacts are designed to ensure reliable interconnects even in the most demanding applications.

Materials and Finish

QMS-052-01-S-D-RA-PC4-K rectangular connectors feature a black UL94V-0 thermoset base. Contacts are made of high-conductivity copper alloy with plating. The contact’s mating interface also features a gold plating which provides superior durability as well as corrosion and vibration resistance.

Working Principle

QMS-052-01-S-D-RA-PC4-K rectangular connectors feature a pin and socket contact design. The pin contacts are inserted into the mating contacts and are held securely in place by a spring clamping mechanism. This ensures a reliable electrical connection between the two boards or cable and board.

Conclusion

QMS-052-01-S-D-RA-PC4-K rectangular connectors are ideal for a wide range of embedded, medical, instrumentation, and industrial control applications. Their low profile design provides high-density connections, and their superior material and finish quality ensure reliable and cost-effective interconnections.
