QMS-078-06.75-H-D is a type of rectangular array type connector. The part number is made up of three major components:QMS, 078 and 06.75-H-D. QMS stands for rugged many-around-multi-strip (RAMS) connectors, 078 stands for the number of contacts in the array and 06.75-H-D is the type of contact used.

The QMS-078-06.75-H-D rectangular array type connector is comprised of an array containing 78 high retention contacts. These contacts are housed within a rugged RAMS interconnect system, which consists of multiple rows of 78 contacts in an array. The contacts are mounted within a ruggedized body design for superior retention and improved board to board and board to backplane connection.

The contact material used in the QMS-078-06.75-H-D connectors is typically copper or brass, with gold plating for superior conductivity. The contacts are configured in a 2.75mm centerline pattern and are rated at 10 - 13A per contact. The contact termination is by dip solder, and the connectors are also compatible with both press fit and conformal coating connection technologies.

The primary application field of QMS-078-06.75-H-D connectors is in industrial and commercial boards. These connectors are used for interconnecting a variety of electronic devices, such as industrial and specialized computers, control systems, and communications networks. The connectors are designed to be used in harsh environments, such as those found in industrial automation and hazardous locations. The connectors are also used in automotive, medical, and military applications.

The working principle of the QMS-078-06.75-H-D connectors lies in the contact design. The contacts are designed to provide superior retention for maximum connection reliability. The contact structure is also designed to reduce crosstalk between pins and boards. Additionally, the contacts are designed to be tolerant to shock and vibration, as well as to provide improved electrical characteristics, such as low operating voltages, current capabilities, and inductance.

Ultimately, QMS-078-06.75-H-D connectors are designed for reliable and cost-effective connections in harsh environments. The rugged construction and the reliable contact design make them highly suitable for a wide range of applications, from large-scale industrial installations to small-scale medical devices.
