557715-2 Application Field and Working Principle

The 557715-2 is a type of memory connector commonly referred to as a PC card socket. It is specially designed to accept, connect, and provide power to a wide range of PC cards. It is a low-profile card socket with 28-pin contact layout that is designed to be shock resistant and reliable for a wide range of applications.

The type of card connector offers robust features like a spring-loaded dynamic contact design to ensure reliable connections and power delivery while meeting both mechanical and electrical requirements. Its low profile enables high-density board packing for integrating multiple cards into a single board. It also offers industry-standard retention force and picking force that meets all the safety and protection standards.

In terms of application fields, the 557715-2 is most widely used in designs that require storage solutions with high current loadings, such as laptops and handhelds. It is a popular choice for applications where robustness and reliability are of the utmost importance, such as automotive and industrial environments. It is also becoming increasingly popular in consumer electronics products such as digital cameras and camcorders, owing to its high durability and dependable performance.

As for the working principle, the 557715-2 features an advanced contact technology that utilizes spring-loaded contacts housed inside the card pocket. The contacts react to the insertion and withdrawal of the corresponding card, and automatically adjust the position as per the card’s size. This ensures that the card is appropriately secured without any manual intervention. Moreover, the integrated contact design guarantees reliable interfacing with the PC card and ensures a secure connection. Additionally, its roll-in-place surface connection technology further simplifies the connection between the PC card and the socket.

The 557715-2 also features dynamic contact, a contact technology which helps the card socket to automatically adjust its contact position and contact force according to the size of the card. This ensures the best possible connection without any manual intervention. Moreover, it prevents potential inadvertent connections during card insertion and removal.

The 557715-2 also offers thermal protection through its innovative design, thus preventing any kind of PCB overheating or misalignment of components due to thermal expansion.

In addition to its aforementioned features, the 557715-2 is also RoHS compliant, thus ensuring that its components contain only the minimum amount of hazardous material. This helps its users to reduce the potential risks associated with hazardous materials.
