Introduction

The QMS-032-05.75-L-D Rectangular Connector is a type of Arrays, Edge Type, Mezzanine (Board to Board) connector that is widely used in the interconnection of boards or modules. This article outlines the application field, working principle, and features of this connector.

Application Field

The QMS-032-05.75-L-D connector is suitable for industrial applications including factory automation, home appliances, sensing applications, and medical applications. It is also a viable choice for mass production since its repeatable connections are designed to be handled quickly.The slender design of the QMS-032-05.75-L-D connector enables it to save space in enclosure cabinets. It is also suitable for high packing density applications since it offers multiple configuration options such as 0.8mm, 1.27mm, 2.54mm, 3.96mm, 6.9mm, 9.5mm, 10.7mm, 19.1mm, and 25.4mm pitch sizes.

Working Principle

The QMS-032-05.75-L-D connector is designed with pins and openings that are mounted on a board, with its body placed within the module, traditionally behind the PCB surface. The pin of the QMS-032-05.75-L-D connector is made up of a dielectric material that prevents stray currents from traveling between the pins.The contact points of the QMS-032-05.75-L-D connector feature stamped and formed metal contacts. The pin is designed to be inserted into the socket with a latch or collar in the form of a bar for ease of operation, and a solder termination for mating connection.The grounding and shielding of the QMS-032-05.75-L-D connector is also provided through the use of strain reliefs, such as screws, nuts, and washers, to reduce interference. It is further sealed with a rubber boot that is placed in between the connector and the mating board to prevent water and dust from entering into the system.

Features

The features of the QMS-032-05.75-L-D connector include:• Compact design that enables it to be used in high density applications.• Ratio of current carrying capacity and voltage holding capabilities.• Low profile and wide array of pitch sizes make it suitable for a variety of interconnection requirements.• Robust design is able to withstand high pressures and vibration without compromising its electrical integrity.• Multiple locking mechanisms available for secure board to board connection.• Stamped metal contacts for quick and reliable mating and connection.• Sealing boot provides additional shielding and water/dust protection.• Easy to install with no additional assembly required.

Conclusion

The QMS-032-05.75-L-D connector is an ideal interconnect solution for many industrial and home use applications due to its small size, robust design, and multiple locking mechanisms. Its various pitch sizes and wide range of current carrying capacity and voltage holding capabilities make it suitable for many high density applications. The ability to seal it with a rubber boot also makes it resistant to dust and water damage.
