The QMS-078-01-H-D-EM2-PC8 is a rectangular connector, designed for array, edge type, mezzanine application (board to board for PC and peripheral equipment). Its main use is for the connection of pc boards and provides a cost-effective and reliable solution for large-scale circuit interconnects. It can be used in a variety of applications and its construction will vary depending on the requirements of the product being connected.

This modern edge-type mezzanine connector incorporates advanced mechanical fastening features with positive latching termination to ensure tight connections. It features a low profile zinc alloy alloy body, contact pins and design for maximum strength and long life. The upper contacts have an increased number of mating cycles and the mounting screw surface ensures a secure connection with no movement. Contact retention force is also increased compared to traditional pin and socket designs.

The QMS-078-01-H-D-EM2-PC8 is fully equivalent to Berthold EC2 type connectors. It is UL recognized, CSA approved and RoHS compliant. It has a current rating of 1.5 A, voltage rating of 250 V and operating temperature up to 80°C for standard versions. It is designed for mezzanine board-to-board, edge card and array connections.

The working principle of the QMS-078-01-H-D-EM2-PC8Rectangular Connector is simple yet strong. It features a positive latching reception which is ideal for making reliable connections between two boards. The upper contact pins are inserted into the female mounting hole on one board, while the lower contact pins are inserted into the corresponding hole on the other board. This essentially forms a tight connection with no movement. The connection is then secured with the surface screw which provides additional retention for ensuring that the contact is not loosened.

The typical applications for QMS-078-01-H-D-EM2-PC8 include industrial machinery, audio and video equipment, telecom infrastructure wiring, and medical electronics. It is suitable for a variety of products, including motherboards, daughter cards, and other board-to-board designs. It can also be used in automotive applications, such as in engine control units or in audio systems.

In conclusion, the QMS-078-01-H-D-EM2-PC8 is a reliable, robust and cost-efficient mezzanine connector suitable for a variety of applications. Its positive latching reception technology and surface screw offers a secure connection, allowing it to be used in both high-duty and low-duty applications. It is RoHS compliant, UL recognized, and CSA approved, offering superior performance and long life.
