Memory Connectors - PC Card SocketsPC card sockets, also known as memory connectors, provide a secure connection of electronic circuits and are used in many applications requiring memory storage or high frequency signal transfer. The MI21A-50PD-SF-EJL memory connector family is a series of high performance, high quality connectors designed for use in both consumer and industrial applications.The MI21A-50PD-SF-EJL family of memory connectors offer up to 70 pins with a 0.8 mm pitch, providing a reliable connection between two printed circuit boards (PCB). These connectors offer a female type contact that is gold plated for more improved compatibility. The connectors also feature an arrow shaft locking system to ensure a secure connection is maintained during operation.The MI21A-50PD-SF-EJL memory connector series is designed for use in a variety of applications requiring memory storage or high frequency signal transfer. The connectors are typically used in a variety of industrial and consumer products including data and cellular communications, personal computing devices, gaming consoles, automotive electronics, modems, and digital cameras. The MI21A-50PD-SF-EJL memory connectors have a wide range of features including high heat resistance, electrical performance, and corrosion resistance. The connectors also feature a low profile design that helps reduce the overall size of the connector and the installation space required on the PCB. The connectors are also designed to provide increased durability and reliability in demanding environmental conditions. Working PrincipleThe working principle of the MI21A-50PD-SF-EJL memory connector family is based on a two-point connection between two boards. This connection is achieved by a series of pins located on the connector body which are connected to the PCBs on either side. The female contact is typically the side that is connected to the board, while the male contact is connected to a cable or other signal transferring device.Once connected, the two sides of the connector come into contact with each other, creating a secure connection that allows for data and signal transfer between the two boards. The electrical signals that are sent between the boards are transferred through the contacts, creating a reliable connection.In addition to the two-point connection of the MI21A-50PD-SF-EJL family of connectors, the connector also features an arrow shaft locking system. This feature helps to reduce the risk of unintentional disconnection during use and ensures that the connector remains in place and secure when handling. The connector is also IP68 rated, meaning it can withstand water and dust ingress and is therefore suitable for use in more demanding environments.ConclusionThe MI21A-50PD-SF-EJL memory connector is a versatile and reliable option for a range of applications requiring memory storage or high frequency signal transfer. Its features, including high-temperature resistance, electrical performance, corrosion resistance, and arrow shaft locking system, make it suited to industrial and consumer applications, particularly those in demanding environments. Its low profile and two-point connection also make it ideal for a range of smaller applications where space is at a premium.
