QMS-052-02-L-D-RA-PC4-TR Application Field and Working PrincipleRectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) is a type of connectors used in the embedded electronic industry, which includes edge-type mezzanine connectors and board-to-board connectors. The QMS-052-02-L-D-RA-PC4-TR is a two-position, dual-row array-type mezzanine connector with wires connecting and acting as both the signal lines and the power lines.The main features of QMS-052-02-L-D-RA-PC4-TR are a low-profile footprint, four-position pitch, edge-type mating, Easy-On type retention, and pull-tab locks. The gold-plated contacts ensure a robust connection, and the gold plating also provides superior resistance to corrosion and minimizes impedance. The board-to-board connector utilizes a low-profile headers and sockets, allowing for optimized design space. The Easy-On type retention is simple and secure, with a tab-lock that provides complete keyed securement. The foldback hook design provides secure board retention and ensures stability.QMS-052-02-L-D-RA-PC4-TR connectors are used in a variety of electronic products from power supply modules to aviation and navigation systems. They are typically used in applications requiring high reliability, such as high-definition on-board recording, interconnections, and power-on signal transfer. The working principle of QMS-052-02-L-D-RA-PC4-TR connectors is based on the use of two electrical circuits to send signals from one device to another. Each circuit has a set of electrical contacts that make contact when the connector is inserted. The electrical contacts are held together by a spring-loaded latch, which secures the connectors when the latch is closed.When the connectors are connected, they create an electrical circuit through which current can travel. The current traveling through the circuit can either be for power, data transmission, or both. The current in the circuit is then regulated to ensure it does not exceed a certain level, which can damage both the device being supplied and the device receiving the current.The advantage of using QMS-052-02-L-D-RA-PC4-TR connectors is that they provide a secure fitting that makes it difficult for the connection to become loose or damaged when subjected to vibration or extreme atmospheric conditions. Their low profile design also makes them ideal for applications where space is limited. The four-position pitch provides for improved durability and greater flexibility in the design of the product.The QMS-052-02-L-D-RA-PC4-TR is an excellent choice for a variety of applications from communication systems and medical equipment to circuit boards and data centers. Its easy-on type retention, pull tab locks, gold-plated contacts, and superior resistance to corrosion makes it an ideal solution for applications requiring reliability and longevity.
