Memory Connectors - PC Card Sockets are a type of electrical connector which allow for the transfer of data and power between the computer and an external device. The PC Card Socket is an important part of the PC-to- PCB (printed circuit board) interface and is used for connecting a variety of peripheral devices.

The PC Card Socket is composed of a female connector attached to the back of the device, such as a mobile phone, and a male connector mounted on the device\'s printed circuit board (PCB). The male connection is typically soldered along the sides of the PCB while the female connection is soldered to the circuit board directly.

55640-20201 PC Card socket is a type of memory connector designed for use in a range of electronic devices. It is a two-piece design sold in modules with two 0.64mm pitch female-female card edges. The one-piece design offers increased durability and usability over traditional memory connectors.

The socket is designed to be low profile and have a low profile card edge allowing it to be used in situations where space is at a premium. It has a retention force of 3N and contact click sound to ensure correct insertion and contact between the connector and card, respectively. The contact areas are gold plated to enhance electrical, chemical, and thermal continuity in different applications.

It is suitable for use in applications such as industrial and machine-to-machine communication, medical equipment, smart cards, automotive, and banking and security systems. It allows for easy connection to various peripherals such as SD cards, SIM cards, and T-Flash cards.

The working principle of the 55640-20201 PC Card socket is simple. It starts when a memory device is inserted into the socket. Upon insertion, the contact points in the socket make contact with the contact points on the device, thereby allowing the device to communicate with the PC. The socket then transfers data to the PC, either by serial communication or by direct connection, depending on its design.

The socket also allows power to be transferred through the connection, which is used to power the device connected to the PC. This is done by connecting the power pins on the device and the PC together, allowing the device to draw power from the PC.

The 55640-20201 PC Card socket is a reliable and efficient way of connecting external memory devices to a PC. It is a versatile solution that can be used in a variety of applications, from machine-to-machine communication, to medical equipment, and automotive. With its simple design and easy installation process, it is sure to become a popular choice for connecting peripherals to PCs.
