QMS-078-02-L-D-RA-PC8 belongs to the rectangular connectors - arrays, edge type, mezzanine (board to board) series. This model has two rows of eight contacts with 0.1” contact spacing and opens to accept termination on one side while the other side seats mate with another connector. The connector is made of LAN FR-4 based material with gold-plated contact surface. It supports RoHS, UL1977 and UL/CSA C-UL-US compatibility.This connector has an overall low profile and a wide range of applications. It is often used in flat panel displays, aviation, computer systems, alphanumeric displays, rail systems and other signal power applications. High-end panel connector applications usually require a high degree of insertion/withdrawal force accuracy, linearity and solid contacts. QMS-078-02-L-D-RA-PC8 features screw milled contacts to support high-speed twisted pairs, which can ensure excellent contact reliability and long life.In terms of its working principle, the QMS-078-02-L-D-RA-PC8 adopts a "close-ended press-fit pin" method. To ensure its reliable connection, the assembly uses a combination of a press fit pin and a nut screw connection. First, the pin press fit into the contact hole, locking it in place, and then the pin is soldered to ensure stable connection. This combination helps to reduce installation time while ensuring electrical connections are reliable and secure.The cost-efficient press fit connection also ensures excellent electrical and mechanical performance. It can tolerate tolerances in the hole diameter up to +/- 0.2mm, and larger tolerances of up to +/- 0.5mm on the soldering pin. Furthermore, this structure can handle temperatures up to 125ºC, ensuring long-term reliability in the field.In addition, the QMS-078-02-L-D-RA-PC8 also has two on-board screw torque settings. One is a preload torque setting for the press-fit pins, and the other one is for the nut screws. This combination allows users to fine-tune the insertion/withdrawal force linearity as well as preload the press-fit pin. The torque settings, in combination with the high-precision hardware, make QMS-078-02-L-D-RA-PC8 a highly advanced and reliable connection solution.To sum up, QMS-078-02-L-D-RA-PC8 is a versatile rectangular connector in the arrays, edge type, mezzanine (board to board) series. It is cost-efficient, and has high insertion/withdrawal force accuracy, excellent mechanical and electrical performances. It is widely used in various industries as a reliable connector solution.The specific data is subject to PDF, and the above content is for reference
