The QFS-078-04.25-H-D-PT4-P is a rectangular connector array, edge type, mezzanine, which is a board-to-board, high-density connector system. It consists of male and female pins and sockets on both sides of printed circuit boards (PCBs). It is particularly designed for applications in the medical and consumer electronics industries, where the higher number of connections required necessitates a denser connection grid.The QFS-078-04.25-H-D-PT4-P is a highly reliable contact mating system with stable mechanical and electrical performance. The male and female pins are precision tapered brass with gold plating for maximum durability and performance. The precision mating allows for accurate and consistent connection and provides optimal electrical continuity.This connector system incorporates contact-sensitive active latches that provide a high level of flexibility and secure connection. The active latch ensures strong yet easy insertion and removal without the use of cables or applications of external forces. Additionally, the contacts include built-in resistors and ground clips, for the connection of multiple grounding points and providing a more secure connection.The QFS-078-04.25-H-D-PT4-P connector array is also designed with the highest mechanical and environmental protection in mind. It incorporates an in-line mounting technique, which enables it to withstand shock and vibration and be used in a wide variety of environments. The pressure contacts have two tabs to protect against reverse insertion, and the contacts are surrounded by a high density rubber boot and overmolding which helps to maintain a fixed contact gap and protects the contact from dust and moisture.Additionally, the QFS-078-04.25-H-D-PT4-P connector has a designed voltage rating of 250V per the UL standard, which ensures safe and secure wiring and reduces the risk of electric shocks. The male and female pins are fully compliant with the UL2603 standard, providing additional safety and reliability.Overall, the QFS-078-04.25-H-D-PT4-P is a high-density connector system perfect for applications in the medical and consumer electronics industries. Its precision-mated gold-plated pins provide consistent and reliable electrical performance, while its reliable active latching and multi-point grounding ensures safe and secure connections. Furthermore, it incorporates an in-line mounting technique, UL voltage-rated compliance, and an IP68 rating for dust and moisture protection, ensuring it will perform in the most demanding environments.
