Memory Connectors - PC Card Sockets

PC Card sockets are a type of connection system designed to be used with portable devices that use non-volatile memory such as USB thumb drives and SD cards. These sockets are used in laptop computers, digital cameras, tablet devices, and other consumer electronics. They are designed to be resilient and robust, withstanding impacts and temperatures extremes. PC card sockets are small, but contain multiple contacts that enable a wide range of functionality.

2057184-2 Application Field and Working Principle

The 2057184-2 PC Card socket is a small form factor type designed for use in tight spaces, such as inside notebook computers. It is designed to accommodate a CDMA/EVDO card, smart cards, and other types of memory cards. The socket has a compact design and utilizes a latch to secure the card in place. The socket\'s contact pads, which are gold-plated for precise connection, enable communication between the device and the card.

The contact pads are arranged such that data is transferred via up-stream and down-stream lanes. The up-stream lane is designed for parallel terminal operations while the down-stream key supports SDR transfer modes. Data is physically transferred through the socket utilizing high-speed data rate protocols such as 8/16/32-bit direct memory access (DMA).

The 2057184-2 PC Card socket is designed to be low power, consuming only 0.5 amps at 3.3 volts. Its high-temperature plastic housing allows it to function in extreme temperatures, up to +100° C. The socket is mechanically robust and impact-resistant, able to withstand shocks and temperature variations. The contact pad\'s gold-plating allows for reliable, corrosion-free connections and provides a low-resistance path for data transfer.

Conclusion

The 2057184-2 PC Card sockets are designed for use in a wide range of applications. Its small form factor, reliable connections, and low power consumption make it ideal for portable electronics. With its high-temperature exposure rating and ability to withstand impacts, it can be used in many extreme environments. The PC Card socket\'s contact pads enable communication between devices and memory cards and allow data transfer at high data rates.
