The QFS-078-02-H-D-RA-PC8 is a type of rectangular connector that belongs to the arrays, edge type, mezzanine board to board category. It is a single in-line arrangement vertical or right angle polarized connector typically used in board-to-board connections of printed circuit boards. This type of connector features two rows of pins. Each row has 8 pins that are 2 mm apart, and the total width of the connector is 7.8 mm.The QFS-078-02-H-D-RA-PC8 connectors are used in a variety of applications, such as communication systems, computers, medical equipment, and industrial applications, and so on. The connectors are designed with a contact surface that provides excellent retention force for mating printed circuit boards and provides a high-reliability connection that ensures signal integrity and board level reliability. The connector also features reinforced insulation walls, a rear overmold, and a standard operating temperature range of -55°C to +105°C. It is also compliant with lead-free requirements, adding to its appeal.The QFS-078-02-H-D-RA-PC8 working principle is quite simple. Its main components are metal contacts, plastic receptacles, insulation walls, and external support frame. The contacts are usually designed with small metal pins or posts that provide the electrical connection between the two boards. When the two boards are mated together, the pins make contact with the contacts on the opposite board and the electrical connection is established. The connectors are typically designed with a self-disconnecting and locking mechanism that prevents accidental disconnection of the two boards.The QFS-078-02-H-D-RA-PC8\'s features and reliability make it an ideal choice for many applications. Its lack of complicated components, along with its small size and flexible board-to-board connection, make it a great option for space-constrained designs. It also features a reliable contact force which is maintained during mating and unmating which ensures signal integrity and board level reliability. Furthermore, its low profile design and reliable contacts make it an ideal solution for high-density board-to-board connections.In conclusion, the QFS-078-02-H-D-RA-PC8 is an ideal solution for a variety of board-to-board connections, owing to its small size, reliable contact force, and low profile design. The connector is easy to use and provides an effective and reliable electrical connection for many applications.
